The Best Travel Water Filters & Purifiers for Every Budget – Tested & Ranked

By Author Steph Dyson

Posted on Last updated: 6th October 2023

If you’re preparing for an international trip abroad, then a travel water filter or purifier bottle should be at the top of your list of essential packing items. 

Not only will you want to avoid getting ill from polluted water sources, but you’re probably also concerned about your environmental impact. A carefully selected water filter can help to solve both of these problems.

But what should you be looking for in a portable water filter and which are the best options on the market? 

I’ve personally trialed multiple portable water filtration and purification systems over the past five years of travel in South America and other parts of the world.

As a result, I’ve been able to identify which are the best for international travel and therefore make an excellent investment for your next trip abroad.

Why do you need a travel water filter or purifier? 

Who doesn’t have a story of getting violently ill traveling abroad?

More often than not, it’s the result of untreated water, particularly as waterborne microorganisms are a real problem in developing countries, where poor sanitation can lead to untreated sewage entering drinking water supplies. 

Diseases such as diarrhea , cholera, dysentery, and typhoid can be transmitted through contaminated water and thus make you very, very sick. 

Diarrhea is the most common illness associated with drinking unpurified water. Luckily, there’s an easy solution: bring a portable water purifier with you on your travels, which quickly and easily filters out dirty water, leaving it safe for you to drink.

What previous clients have said:

“Steph’s itinerary exceeded all expectations. She provided off-the-beaten-path hikes, great restaurants and accommodations, and very helpful local contacts. Due to the weather we had to deviate from our original plan, however Steph quickly responded to our email during the trip with further recommendations. Her service took all the guesswork out of planning our vacation and led to the most fun and unforgettable trip we have ever had!”

The problem with single-use plastic water bottles

What’s more, relying on bottled water – which is always safe to drink – presents its own problems. Reuters produced graphics to illustrate the scale of the problem , showing how every minute, one million single-use plastic bottles are purchased around the world.

This works out to 1.3 billion bottles per day or 481.6 billion bottles per year.  

Many single-use plastic bottles are widely recyclable. Unfortunately, most aren’t, and instead end up in landfill where they will take at least 450 years to degrade . Yes, seriously. 

Imagine you’re on a one-week international trip and you drink the recommended two liters per day. Each day, you purchase two single-use plastic bottles containing one liter of water; by the end of the week, you’ll have used 14 single-use plastic bottles.

But what if you’re on a two-week trip? Or a month? Or a year? Your environmental impact starts to build up – and so does the cost. 

Why travel water purifiers are a sensible economic choice

If you can expect to spend around $2 USD per day on bottled water, many of the purifiers listed in this guide will see you break even after just a two-week trip or one week if you’re traveling in a pair.

What’s more, your water purifier can be used on every trip you take in the future, making them an environmentally- and budget-conscious piece of travel equipment.

What is the difference between water purifiers and water filters?

Both “purifier” and “filter” are thrown around a lot, but did you know they actually have a crucial difference? 

Water filters – such as those like Brita filters you might find in your home – can remove impurities such as small particles and unpleasant odors such as chlorine (which is often used to kill micro-organisms in the water to ensure that it’s safe to drink in the first place). 

This type of system removes waterborne protozoa (parasites such as Giardia and cryptosporidium oocysts ) and bacteria (single-celled organisms such as E. Coli and salmonella). 

However, water filters are unable to remove some of the most dangerous impurities in the water: viruses.  

According to the Centers for Disease Control and Prevention, viruses such as rotavirus and norovirus are the smallest of all waterborne disease-causing microorganisms and can pass through filters with pore sizes of between 0.1 and 0.4.

Therefore, if a purifier has a membrane larger than this, viruses are not caught by the filter and instead pass right through with the water itself.

Water purification , on the other hand, removes all three of these classes of microbes and therefore provides complete protection to the drinker – thus stopping you from getting ill. 

Which type of travel water purifier do you need? 

It can feel like a herculean task when faced with the variety of travel water purifiers on the market to identify which is best for you and the type of international travel that you do. 

Add into the mix the range of prices, sizes, and exactly what they safely remove from the water, and you can be left feeling completely perplexed. 

To make things simple, water purification systems can be broken down into the following types of products:

Which water purifiers for international travel exist on the market?

There’s a wide range of different options available at different price points and for different styles of travel. 

I have personally trialed all of the water purifiers listed – except for two as indicated – and vouch for their effectiveness based upon this. 

UV water purifiers: Steripen Adventurer

Trialed by me: yes

The only portable UV water purifier on this list, the Steripen Adventurer kills all bacteria, viruses, and parasites found in water and does so almost in the blink of an eye. Seriously. 

It looks a bit like a pen that you dip into a bottle full of untreated water. At the click of a button, you begin to “stir” the water using the Steripen and in just 90 seconds, you’ve purified a liter of water.

A light on the body of the device lets you know exactly when to stop stirring and whether the water has been successfully purified or not. 

To use the Steripen Adventurer, you need to buy your own wide-mouthed water bottle to use with the purifier (I’ve found the Nalgene water bottle to be an ideal size for this), meaning you can ensure that you have enough water for a day’s hike or drive if you fill up a couple of water bottles. 

It’s also handy if you’re sightseeing around a city and don’t want to purify loads of water in one go; just purify a small amount, ask for your bottle to be filled up from the tap in a restaurant, and purify the water you need. 

It’s also the lightest portable water purification system on this list, weighing in at only 70g – although you will need to have your own water bottle at hand. 

Some reviewers have claimed issues with the battery and that it has failed at crucial moments; I have not personally faced any such issues during my four years of ownership. 

Things to consider about the Steripen Adventurer

The main negative about the Steripen Adventurer is the fact that the batteries it requires are really, really weird (like seriously, I’ve never seen them before) and saw me buying a large box of them from Amazon (and of which I’ve used about four because the batteries do seem to last forever). 

Secondly, it is a delicate piece of kit with the UV light easy enough to break if you don’t take care of it – although this isn’t an issue that I have faced.

Thirdly, you cannot use the Steripen for murky water as suspended soil particles in the water can shield microorganisms from the UV light, thus preventing them from being killed in the process. 

Therefore, if you plan on backpacking a lot on your trip or taking water from backcountry water sources that could have been contaminated by humans, this isn’t a great option for you. 

Finally, it’s also one of the most expensive of the water purification systems available (coming in a tiny bit cheaper than the Grayl). However, in my experience, you get what you pay for. 

Check out my full review here: Why the Steripen Adventurer is the best backpacking water purifier .

I’ve personally used the Steripen Adventurer for close to five years and find it the most convenient and easy-to-use travel water filter for travel on the market.

90 seconds is all you need to purify a one-liter bottle of water and remove protozoa, bacteria, and viruses, leaving water that is perfectly safe for you to drink immediately. 

It’s ideal for using with contaminated tap water in developing countries but not a great choice for backcountry hiking because it can’t filter out sediment.

Independent tests have also shown that the quality of the water that is filtered is not as good as the Grayl Geopress.

Bottle water purifiers: LifeStraw Go

Trialed by me: no

The LifeStraw Go is often touted by backpackers as the best water filter for traveling abroad because of its ease of use and accessible cost.

This is a bottle water purifier, which means that you fill the bottle up, re-insert the straw filter, and then suck through it. The water is purified as it travels up and into your mouth. 

The process is therefore instantaneous, requiring no time, planning, or effort on your part. 

Inside the filter cartridge itself, activated carbon removes unpleasant chlorine or other odors from the water.

It also comes with a carabiner clip so that you can easily attach it to your bag while out sightseeing in a city or to your rucksack when you’re on the trail. 

Things to consider about the LifeStraw Go

However, there’s a big but for any travelers. 

The LifeStraw Go doesn’t remove viruses from the water. While the company doesn’t actually claim it will, I honestly didn’t know this vital piece of information until I started researching this article. 

As a water filter bottle so regularly recommended to backpackers, this is a crucial bit of information that lots of people seem to have missed. 

Tap water in developing countries (and all across South America where I’ve traveled) is rife with viruses; throughout this continent and the world in general, 1 in 3 people (that’s 2.2 million people) don’t have access to safe, clean drinking water according to the World Health Organisation and UNICEF . 

Therefore, the LifeStraw Go leaves you open to stomach upsets and other serious illnesses.  

What’s more, you will need to replace the cartridge in this purifier on a regular basis if you plan to use it long-term on a trip.

The manufacturers recommend every three months – and you’ll know when it’s time to replace the bottle as it’ll start becoming increasingly more difficult to suck water through the straw.

This is costly (effectively the price of buying a brand new LifeStraw Go), so is definitely something to consider. 

A friend of mine who reviewed this product for me also mentioned how the filter is prone to leak when placed in direct sunlight or when it’s at altitude.

On the place she had an incident where the bottle leaked, leaving her seat wet for the entirety of her flight, which isn’t exactly ideal. 

The LifeStraw Go doesn’t remove viruses so isn’t safe for day-to-day travel use in developing countries where tap water isn’t safe to drink. 

A lot of people ask which is better, the Grayl or the Lifestraw Go, but it’s not even a fair contest as they’re aimed at different things (read my Grayl Geopress review below to learn more).

Instead, this is a great water filter bottle for hiking in backcountry destinations where the river water is unlikely to have been tampered with. It’s affordable and easy to use. 

Buy the Lifestraw Go on REI or Amazon

Bottle water purifiers: Water to Go

The Water to Go is another water purifier bottle.

When I first came across this brand, I was really impressed with the price of their products. This is a top water purifier as it’s one of the cheapest models on the market and can filter all of the nasties that you don’t want to have in the water: bacteria, viruses, and protozoa, as well as filtering out heavy metals such as lead and other harmful chemicals. 

It’s also designed to make sure that the water tastes good; inside the filter cartridge are activated carbon particles to reduce any unpleasant taste or odors in the water. 

If you buy it on Amazon, it comes with a replacement filter, which you’ll likely need after three months of use, while additional replacement filters are relatively affordable at around only $13 USD a pop.

Things to consider about the Water to Go

While the Water to Go is probably up there as the best filtered water bottle for international travel, there are some downsides.

Many users have reported that the bottle does leak if it isn’t kept completely upright – which is a bit of an issue if you’re using this water filter bottle for travel, as keeping a bottle upright is nigh on impossible.

Some reviews have also noted how it’s not a very durable water filtration bottle, so you’ll want to make sure that you don’t drop it (the Grayl Geopress, below, is a far sturdier alternative). 

With the larger bottle, it’s also hard to see how much water you have remaining as the plastic is opaque (the smaller 500ml bottle is clear so you can see this), which can be annoying. The black design isn’t great for hot countries anyway as it causes the water to heat up rapidly. 

For me, the bottle is a little on the small side (I don’t like to travel without a one-liter water bottle), particularly as it can be hard to get the final hundred milliliters from the bottom of the bottle – so capacity is never fully 750ml. 

This isn’t designed to be a squeeze purifier (check the Sawyer Mini below instead for that), so you can’t use it to purify water into a glass – instead, you’ll be drinking from the water bottle throughout.

If this is a game changer for you, I’d recommend the Steripen Adventurer instead.  

This is among the cheapest and most affordable portable travel water purifiers and delivers with speed, capacity, and ease of use. It’s also significantly lighter than the comparable LifeStraw Go and has a slightly larger capacity. 

However, you’ll want to keep it upright to avoid leaks and I would avoid the black design if you want to keep your water cool.

Squeeze purifiers: Sawyer Mini

The Sawyer Mini is the cheapest and one of the most lightweight water purifiers on this list.

Like the Steripen Adventurer, you can filter water in advance as you squeeze dirty water from the provided container through the filter and into your own bottle. 

It also should last a lifetime, with no need to replace the filter cartridge – at all. This is because you can flush the filter out using the small syringe that comes with the filter.

This is the only filter on the list that should never require replacing and, for the price, this makes the Sawyer Mini incredibly hard to beat in many respects.

You can also link it up to a hydration bladder such as the Platypus and suck the water directly from the bladder through the filter. Similar to the LifeStraw Go, this does require some effort because of the resistance provided by the filter. 

Things to consider about the Sawyer Mini

However, as with the LifeStraw Go above, the Sawyer Mini doesn’t remove viruses from the water.

Therefore, it’s really only recommended for backcountry hiking trips with reasonably clean and reliable water sources, rather than something to use when you’re traveling through developing countries and drinking tap water that’s potentially contaminated with waterborne viruses.  

I also found this pretty hard to use for one main reason: the bag tears pretty easily if you’re not super careful when you’re squeezing.

This is something that the manufacturers highlight as being an issue (and subsequently, you should be more careful) but was a real deal-breaker for me and the main reason that I opted instead for the Steripen Adventurer . 

I also found that, because of the degree of care you needed, the whole process takes a lot more time than it needs to (around two minutes, and a lot of pressure, for a liter of water).

This isn’t helped by the fact that the filter cartridge can clog easily and you need to backflush the system using the provided syringe to enable it to work again. 

On balance, neither my dad or my brother have faced similar issues when using the Sawyer Mini and it has rapidly become my dad’s water purification system of choice.

That said, if you’re just starting out with the Sawyer Mini, you’ll want to invest in a couple of spare bags in case you do spring a leak. 

This is a great little water purifier at a supremely accessible price, but the fact that it doesn’t filter out viruses means that it’s not ideal for travel.

Instead, this is probably the best water filtration system for backpacking and backcountry hiking, but only in areas where the water sources are unlikely to be polluted with waterborne viruses. 

Sawyer has just recently launched their new Select Water Purifiers and Filters range, with the S3 range aimed toward international travel as it removes bacteria, protozoa, viruses, heavy metals, and chemicals (including pesticides).

It’s a lot more expensive than the Sawyer Mini (coming in at a similar price to the Steripen and Grayl) but looks like it could be an excellent alternative. 

If you’ve tried this new product, please let me know your experiences!

Press purifiers: Grayl Geopress

The Grayl Geopress is a very different type of water purifier from those discussed above.

It’s a bottle that you fill with water, before inserting the filter cartridge and pressing down, thus forcing the water through the cartridge in one swift movement.

It’s a really popular bit of gear for travelers because it does eliminate all bacteria, protozoa, and viruses, meaning it’s a reliable source of fresh and safe drinking water. 

What’s more, the Grayl Geopress has a capacity of 710 ml, which is comparable with all of the bottle water filters available on the market.

Finally, the water bottle itself is the most durable of those in this guide and you can guarantee that dropping this bottle isn’t going to cause serious harm to the filter. It also won’t leak, even if it’s stored upside down. 

Things to consider about the Grayl Geopress

However, my biggest issue with using the Grayl Geopress is how small the capacity of the bottle is. 

While they claim that it filters 710 ml, I found this to be less because of the dribble of water at the bottom of the bottle that ends up being out of reach of the cartridge and therefore doesn’t get purified. 

What’s more, I’ve found that the act of pressing the water through the filter genuinely starts to hurt my hand after a while. You need some serious guns (US readers: muscles!) to work this filter and it can feel like a bit of an ordeal to be doing this multiple times per day. 

It can also get extremely tough to press if the water has lots of sand or silt in it, so you’ll probably want to try and pre-filter this (a handkerchief or similar piece of cloth can be useful for this). 

Note that at altitude, I’ve also found that the filter cartridge starts trying to remove itself from the bottle due to the pressure, which caused some leaking. Therefore to avoid this, you may want to ensure that it’s not completely filled before you fly. 

The Grayl Geopress left my hands hurting, however, independent testing has proven that it provides some of the cleanest water post-purification, blowing the Steripen Adventurer out of the water.

What’s more, it can filter water containing particulates, so can be used in practically any context and still guarantee safe drinking water in a matter of minutes. This makes it an ideal option as a water filter for traveling abroad. 

Issues remain in the fact that it doesn’t have space for that much water and it’s really heavy, which is the compromise for the quality of the purification system inside. 

Buy the Grayl Geopress on REI , Backcountry or Amazon

Gravity purifiers: Sawyer One-Gallon Gravity Filtration System

Sawyer’s One-Gallon Gravity Filtration System is basically a one-gallon bag attached to the Sawyer Mini. You hang the bag in a tree or off your pack and watch as gravity pushes the water through the Sawyer Mini and into your receptacle of choice. 

Because gravity, rather than your hands, is doing all the work, this version of the Sawyer is a lot more durable. Additionally, the Sawyer Mini filter that comes with it has the same long lifespan – 100,000 gallons of water or, what the manufacturers claim is equivalent to a lifetime of water. 

This is a great option if there are a number of you on a trip, as you can quickly and easily filter water for cooking or drinking. 

Things to consider about the Sawyer One-Gallon Gravity Filtration System

However, as with the Sawyer Mini, this water purification system doesn’t filter viruses, so isn’t ideal for travel.

I saw some guys using one on the O Circuit in Torres del Paine and it was great for this type of situation: the water sources in the park are largely uncontaminated by humans or chemicals, so the water just needed filtering for sediment. 

Again, the Sawyer One-Gallon Gravity Filtration System doesn’t filter viruses, so isn’t a good choice for general travel. However, like the Sawyer Mini, it’s a great outdoor water filtration system for backpacking and backcountry hiking, particularly if you’re travelling in a group. 

Buy the Sawyer One-Gallon Gravity Filtration System on Amazon

Chemical water purification

Perhaps the most widely-used means of purifying water is through chemicals such as iodine or chlorine.

Tablets or drops can be bought at a very inexpensive price and need to just be added to the water you are trying to purify.

That said, you do need to wait from 30 minutes to four hours before it is safe to drink the water. 

Iodine purification tablets and drops don’t purify water from cryptosporidium oocysts and they can also leave the water with an unpleasant taste, although this can be circumnavigated with the help of additional tablets that neutralize the flavor. 

Chemical water purification tablets or drops are the ideal backup for any of the other methods identified in this guide. However, they are not a great solution for travel, particularly as you’ll want clean, drinkable water available at a moment’s notice. 

Get water purification tablets on REI , Backcountry or Amazon

If you’re traveling and don’t have access to any water filtration system, boiling is the most reliable method of acquiring safe drinking water. 

According to the Centers for Disease Control and Prevention, it’s necessary to boil water for one minute to ensure that all waterborne microorganisms are killed. 

However, in my experience, if there’s no kettle where you’re staying (something very common in South America), then it can take a long time to boil a few liters of water. 

You also need to do this in advance (this method doesn’t allow you to purify while you’re out and about), while the pan you boil water in can leave an unpleasant metallic taste in your water. 

Boiling water is a last-resort option for acquiring safe drinking water and one that, while functional, can take time and result in metallic-flavored water. 

I personally think investing in a water purifier is worth the cost for its ease of use and is the best way to get clean drinking water when you’re traveling abroad. 

Which is the best travel water filter for international travel?

The best travel water purifier for simplicity: I personally prefer the Steripen as I’ve found this the fastest and most reliable method of treating tap water throughout South America.

Not only can you purify one liter of water in 90 seconds, but this also requires practically no effort on your part. 

The Steripen Adventurer removes everything from bacteria to protozoa and viruses making potentially contaminated water fit to drink. You need your own water bottle in addition to the filter itself, but I’ve found this to be a reliable little device, which is also highly portable, lightweight and small. 

Buy the Steripen Adventurer Opti on REI or Amazon

The best travel water purifier for every single circumstance: However, the Grayl Geopress comes a close second in the contest for finding the best travel water filter, despite a couple of reservations I have about the product.

This is because it removes practically everything from the water, including chemicals, hard metals, and microplastics and it even works with water containing particulates – something that the Steripen Adventurer isn’t capable of doing. 

The downside to the Grayl Geopress is the size and weight of the bottle and filter, which may put you off, but are something you can overlook in order to be guaranteed safe drinking water wherever you are on the road.

Hi. Thank you for this valuable information. Can I please ask you a question, and thanks in advance if you can help :)

I plan on doing a year backpacking and hiking in South America next year, so I need something that works 100% on everything - bacteria, viruses, protozoa, floating particles. It looks like the Geopress is the only option that ticks all of these boxes, am I right? As you mentioned, the Geopress is heavy/bulky, so is not ideal for my situation as I need to be fairly lightweight.

In my case, what would you recommend? Would it be a good idea to use a Sawyer Squeeze, and have some purification tables to remove the potential viruses?

Tuesday 28th of November 2023

Hi Aidan, I travelled across South America just using my steripen and didn't get ill. If you want the belt and braces approach, the Geopress is the best option. I wouldn't use purification tablets as they make the water taste awful. Steph

None of what you covered will prevent sickness in New Guinea. All of those items were good but it was the food not water that caused the problems in Port Moresby. I was sick the entire time until I went over to Rabaul on the other side of the country. Before I left the US I bought several of those items like the Lifestraw and grayl geopress. after 4 years of traveling in 32 country's I left them behind to lighten the bags. I mostly just found it easier to treat the reactions by traveling with pepto all the time. Or gaviscon in AU and nz. Even when I was a otr driver in the USA it was always the food not the water that caused the issues.

Wednesday 20th of September 2023

Hi Vance, the issue with food is typically as a result of the water being used (salad often makes people sick because of it being washed in water that has bacteria or viruses). Steph

Great article, I appreciate it! Thank you very much. I found out one filter but it is a bit bigger, so can anyone share some information with me if it is good to use this filter for walking or to buy another one? https://www.aussiestormshop.com.au/lifestraw-peak-series-1l-filter

Thursday 7th of April 2022

I love my Grayl! Great for foreign travel, I fill up with tap water, etc. all the time. Less worries about bottled water, as I found sometimes the hotel can be a little stingy. :) No issues pressing it, I just set it down and lean on it a bit. I don't try to hold and force it. A little heavy for backpacking, but I take it anyway. I carry a 1l. bladder and a couple of presses fills it up as well.

Friday 22nd of April 2022

Great, thanks for sharing! It's definitely one of the best options! Steph

Tuesday 29th of March 2022

I was very surprised to see your comment that LifeStraw doesn't remove viruses... as my research told me otherwise. I just double checked their website. They claim:

LifeStraw’s membrane ultrafilters are capable of removing 99.999% (log 5) of viruses, 99.999999% (log 8) of bacteria (including E. coli), 99.999% (log 5) of parasites (Giardia, Cryptosporidium, etc.), and 99.999% (log 5) of microplastics.

So not sure where your information is coming from, but this definitely gives me pause and I will do more research to confirm before buying.

@paul, hello - on their detail data sheet info, it’s just the PURIFIERS listed that remove viruses [Lifestraw “Mission”, “Family” and “Community” product items]. The other Lifestraw products on that page are FILTERS and they do not remove viruses [“Lifestraw”, “Lifestraw Go, Play, Universal, Steel” and “Lifestraw Flex” ]. [pardon my emphasis with the caps but it helps me to keep it straight]. Here’s the URL: https://cdn.shopify.com/s/files/1/2631/0778/t/4/assets/LSGo-Play-Universal-SteelEvidenceDossier-1544005030340.pdf?9890004779047419701

Wednesday 1st of February 2023

@paul, I just checked your link and checked on their webpage too, and it doesn't say anything about virues. I was looking into it too as I would be interested if it removes viruses as well

8 Travel-Friendly Water Purifiers That Actually Work

By Kaitlyn McInnis

It’s easy to take water for granted when you live and work in a building that has clean drinking water running in abundance from every faucet—but that’s not always the case when traveling abroad or heading out into nature while camping or hiking.

I learned that the hard way when I spent three months in a cabin in the woods that ran on lake water. I subscribe to the eight-cups-a-day rule, and I have an emotional support water bottle that I carry from room-to-room at all times. I am, simply put, a big water drinker . And sure, I was able to drive to the grocery store to buy water—but finding a water purifying solution that allowed me to drink the lake water was much more convenient, eco-friendly, and budget-friendly than having to add gallons of drinking water to my grocery list.

Over the last month or so, I’ve tried a handful of different water purifiers and filtration systems at my cabin on the lake . Of all the styles I tested, there were eight that I will continue to use on future trips to the woods and bring with me on my next vacation abroad . Read on for the best high-quality portable water purifiers and filters to ensure you always have access to bacteria- and sediment-free drinking water on the go.

Larq PureVis water bottle

Best water bottle

The Larq self-cleaning bottle is by far my favorite portable water purifier that I’ve tried so far. The 17-ounce water bottle features unique UV-C LED technology that neutralizes 99.999 percent of harmful bacteria such as E-coli and salmonella in under 60 seconds at the push of a button. The stainless steel bottle also activates a self-cleaning mode every two hours which helps to keep the bottle itself from developing that dreaded musty water bottle smell that can occur over time. Despite its high-tech functionalities, you can drink out of it like you would any other water bottle; the UV technology is confined to the bottle cap and does not interfere with filling or drinking from the bottle itself.

LifeStraw personal water filter

Best straw filter

Sometimes carrying around a water bottle or water filtration system is just not practical—which is where the LifeStraw comes in. This compact personal water filter works as a regular drinking straw while instantly filtering out over 99.999 percent of bacteria, parasites, and sediment such as microplastics, silt, sand, and cloudiness. The compact straw and filtration has an unlimited shelf life and can easily slip into your handbag or backpack for emergency use . Use it to take a sip straight from a flowing stream or drink a glass of tap water from the faucet in your hotel room.

Sawyer Squeeze water filter system

Best for backpacking

Lightweight and easy to transport, the Sawyer Squeeze water filter system will be your best bet if you’re setting up camp in the woods but are trying to keep your load light. The hollow-fiber membrane filter removes more than 99.999 percent of all bacteria, viruses, and parasites at a rate of about one liter per minute—but we particularly like this system for its compact and easy-to-use squeeze bottle design. All you have to do is fill up the pouch with water, attach the hollow-fiber filter, and squeeze the water through the system into your preferred water bottle (or even directly into your mouth).

Platypus GravityWorks water filter system

Best for large quantities of water

The GravityWorks water filter system is my personal favorite for filtering large volumes of sediment-heavy water. The water filtration system works—as the name suggests—by using a combination of gravity and microfilters to ensure removal of up more than 99.99 percent of bacteria and parasites as well as any sand, dirt, or sediment that can often appear in lake or stream water.

Katadyn Steripen Classic 3 UV water purifier

Best multi-purpose purifier

The Katadyn Steripen Classic 3 UV is a hand-held water purification device made to destroy everything from parasites to bacteria and viruses in less than 90 seconds thanks to the built-in ultraviolet (UV-C) light rays. The handy device easily fits over cups, mugs, and even most water bottle mouths for added convenience and comes with a pre-filter for removing sentiment, microplastics, and other particles that might not be visible to the naked eye. Bring it on family or group camping trips where you can divvy up who carries what.

Potable Aqua water purification tablets

Best tablets for groups or families

The Potable Aqua water purification tablet is a great option for purifying large quantities of water to have on hand over a weekend at a lake house or campsite. The two-step process helps to eliminate waterborne bacteria and viruses in up to half a gallon of water per germicidal iodine tablet. The second bottle is a neutralizing tablet, which, although not necessary to ensure safety, helps to improve the overall flavor of the water so you don’t taste the remnants of iodine or anything else that might be floating in the water.

Aquatabs water purification tablets

Best tablets for individuals

Looking for something ultra-compact to throw into your emergency preparedness kit, wallet, or jacket pocket? Aquatabs Water Purification Tablets are extremely small and slender (we’re talking half the size of a credit card ), but despite the compact size, the powerhouse purification system can remove up to 99.99 percent of bacteria and viruses from half a gallon of water per tablet thanks to the neutralizing salt-based chlorine known as sodium dichloroisocyanurate.

Larq PureVis pitcher

Best pitcher

The Larq PureVis pitcher isn’t quite as portable as other options I’ve tested out, but it’s the best option for setting up in the kitchen during a long-term stay abroad or at a Airbnb in the woods . The water-purifying pitcher removes contaminants like bacteria, lead, mercury, pharmaceuticals, and VOCs while the innovative self-cleaning filter helps to prevent bio-contaminant growth from developing within the pitcher itself.

The Best Filtered Water Bottles

By Tim Heffernan

Tim Heffernan is a writer who covers air and water quality and sustainable-energy technology. He prefers Flare-brand match smoke for purifier testing.

Filtered water bottles let you create better-tasting water almost anywhere you go. After we tested five of them, our pick is the Brita Premium Filtering Water Bottle . Its activated carbon filter removes chlorine compounds, which are used as a disinfectant in most public water supplies and are the cause of the off-flavor that many people dislike about tap water.

But we have reservations about filter bottles in general. Most of them make you suck the water through the filter, and that’s not exactly easy—it’s like drinking a thick milkshake through a straw. And most bottle filters remove only chlorine, not other things you may be concerned about, like lead, PFAS (per- and polyfluoroalkyl substances), and microplastics.

If you have access to another source of filtered water, such as a filter pitcher , office water cooler, or under-sink filter , then using that to fill a reusable water bottle is a more convenient and versatile way to bring along fresh-tasting water that’s likely more thoroughly purified too.

Brita Premium Filtering Water Bottle

Fresh-tasting water wherever you are.

Certified to remove chlorine from tap water, this model improves the taste, and it comes in a variety of leakproof designs. But, like all filtered bottles, it needs upkeep and is difficult to drink through.

Buying Options

May be out of stock

The Brita Insulated Filtering Water Bottle is NSF/ANSI certified (PDF) to reduce the chlorine disinfectants that can give tap water an unpleasant flavor. The bottle itself is well designed for carrying with you to work, school, outdoor events, and errands. It’s sturdy, didn’t leak a drop in our tests, and was easier to drink from than some of the competition, thanks to its comfortable mouthpiece. It comes in many colors, a few sizes, and both insulated stainless steel and BPA-free plastic (which is not insulated) versions. The plastic version is dishwasher safe for cleaning, and the replacement filters, which last about two months, are less than $3 apiece.

The research

Why you should trust us, who this is for, how we picked and tested, our pick: brita premium filtering water bottle, another good filter bottle if pathogens are a concern, the competition.

In testing and writing about water filters for Wirecutter since 2016, I’ve spoken with the two main US filter-certification organizations, NSF and the Water Quality Association, to understand how their testing is conducted. I’ve interviewed engineers and product managers at many water filter manufacturers to interrogate their technologies and claims. And I’ve spent years just living with and using multiple types of water filters, since overall durability, ease and cost of maintenance, and user friendliness are important considerations in something you use multiple times a day.

Filtered water bottles create better-tasting water wherever you go. The kind we tested are aimed at commuters, high school and college students, caretakers, and other people who are always on the move. The bottles are sturdy, attractive, and slip easily into a backpack, purse, briefcase, or messenger bag.

The filters usually work by removing the chlorine disinfectants that give lots of tap water an off flavor. But that’s all most of them do. Most do not protect against other contaminants that may be of concern to you, like lead, PFAS, or bacteria.

The filter bottles we tested (with one exception ) are not meant for hikers and wilderness adventurers. That’s because they aren’t designed to be as small and light as possible, to be compatible with a variety of bottles and storage containers, or to remove disease-causing pathogens from untreated water.

That means they’re also not meant for emergency filtration, such as during a boil-water order following a flood or other natural disasters.

Finally, our testing showed that they’re not practical for children. Most filter bottles require you to suck the water through the filter, and that takes considerable force. Youngsters will have a far easier time using regular bottles filled with water from a filter pitcher or other filtered source.

Frankly, so will adults. Bear that in mind when deciding if you need a filter bottle at all.

We applied the same criteria for filtered water bottles that we do for filter pitchers and dispensers, faucet-mount filters, and under-sink filters: Any claims that bottles remove heavy metals like lead and mercury, industrial compounds like pesticides, and pathogens like bacteria had to be NSF/ANSI certified or tested to NSF/ANSI or similarly stringent standards by accredited independent labs, with the test results publicly shared.

For filter bottles that claim only to make water taste better—which is by far the most common claim—we didn’t require stringent certification, because that’s an extremely simple thing to do. You just run the water through an activated-carbon filter, which are cheap and widely produced.

We did limit our search to filter bottles from well-known brands that have a history in the filtration sector. Numerous filter bottles are now available from small, little-known companies, and though many of them likely perform just fine, we place a lot of emphasis on accountability and an established record in an area as central to well-being as clean drinking water.

We eliminated bottles with pour-through filters, where you fill an upper reservoir and wait for the water to drip through the filter via gravity. They’re slow, and they take several fillings of the upper reservoir to create a full bottle of water—the opposite of on-the-go convenience.

Our testing focused on livability and usability factors. Is a bottle comfortable to hold? To drink from? To refill and to clean? Because filter bottles are generally tall and narrow, their interiors are hard to wash by hand, so we gave points to dishwasher-safe models.

We also came to prefer bottles whose mouthpiece is covered by a cap when not in use. Some have exposed flip-up mouthpieces, and though they’re convenient, they can also pick up dirt while jostling around inside a bag.

We filled our test bottles and kept them upside-down for several hours, shaking them vigorously every 30 minutes or so, to check for seepage. A spill inside your bag is annoying at best, and quite expensive if it ruins some electronics.

We assessed if replacement filters are easily available and affordable. Filters have finite lifespans; you’ll need a new one every few months if you use your filter bottle daily.

The BPA-free plastic Brita Premium Filtering Water Bottle is our pick among the filter bottles we tested. It’s sturdy, comes in a variety of colors and sizes , and is NSF/ANSI certified to reduce chlorine (PDF) , which is the main culprit in bad-tasting tap water. (Note that the plastic versions we recommend are not insulated, although some listings online label them as such. The insulated stainless steel versions keep water cold longer.) Here’s what we liked about the Brita bottle:

It’s relatively easy to drink from. The effort required to suck water through the straw-like filter is lower than with some competitors—though it’s still like drinking a thick milkshake through a straw—and the soft, rubbery mouthpiece is a comfortable size and shape.

It can make tap water taste better. The bottle uses a simple activated-carbon filter. It efficiently captures the chlorine compounds that are commonly used to disinfect water supplies, which, to many people, make the water taste bad.

The flip-top cap allows for one-handed drinking. The cap protects the mouthpiece and keeps it clean when you’re not using it. You just press a button, and the cap pops open to let you take a drink. We preferred its convenience to bottles with twist-off caps, which require two hands and can be dropped or lost. And we preferred both of these designs to bottles with flip-up spouts, which aren’t protected by a cap and can pick up dirt inside a bag or purse.

We didn’t experience any leaks. To test for leaks, we filled all of our contenders then placed them upside down for several hours, giving them a vigorous shake every half hour. The Brita bottle didn’t leak a drop (and neither did any of the other bottles).

The plastic parts are dishwasher safe. Like any reusable bottle, the Brita bottle should be cleaned regularly. To clean yours in the dishwasher, remove the filter from its housing and then place the housing and all other parts on the top rack. (Brita said the stainless versions should be hand-washed.)

Replacement filters are inexpensive. The replacement filters (model BB06) cost less than $3 apiece. They’re rated to last for 40 gallons or two months.

Flaws but not dealbreakers

This is a flaw of the category, not the Brita bottle specifically, but it bears emphasizing: Filter bottles are harder to drink from and fussier to refill than plain reusable bottles. It takes real effort to suck water through the filter. The straws drip when you pull them out to refill the bottle, and they’re just one more thing you have to clean and maintain.

If you have a convenient source of filtered water available—from an office water cooler, say, or a pitcher or under-sink filter at home—you’ll probably be happier with a versatile reusable bottle such as the ones we recommend .

The carry handle on the Brita bottle is attached to the flip-up cap. That puts the weight of the entire bottle on the small plastic latch that keeps the cap closed. Using the handle to pick up the bottle shouldn’t stress the latch too much, but we would not recommend carrying the bottle by the handle, hanging it from a carabiner while walking around, or pulling the bottle out of an overstuffed bag by yanking on it.

If you’d like a filter bottle that both makes treated water taste better (by removing chlorine) and also removes bacteria and protozoa (like Giardia ) that can be present in untreated water, we recommend the BPA-free plastic LifeStraw Go Series bottle . It comes in multiple colors and two sizes (22 and 34 ounces), and an insulated stainless steel version is available in 24 and 34 ounces.

All of LifeStraw’s bottles use a dual filter, with an activated carbon element to reduce chlorine and a hollow fiber membrane filter that physically blocks waterborne bacteria, protozoa, and other particles above 0.2 microns in diameter, including microplastics. (It does not capture viruses, which are smaller still.) You can read LifeStraw’s in-house and independent test results here (PDF) .

The hollow fiber membrane filter takes more strength to suck water through than the Brita Premium Filtering Water Bottle’s plain carbon filter, and because pathogens are not present at dangerous levels in properly treated tap water, the Go bottle is overkill for most everyday use. However, if you travel frequently to places where unsanitary tap water is a concern, the Go bottles are more convenient (and stylish) than camping-oriented filters or chlorine tablets.

A screw-on cap protects the bottle’s mouthpiece from dirt when it’s not in use, and it prevented any leaks in our testing. However, it requires two hands to use, and while detached, it can be dropped, lost, or separated from its companion in a dish rack or crowded cabinet.

The carry handle is molded right into the lid, and it’s sturdy enough to stand up to moderately rough trail hiking. Commendably, LifeStraw sells replacement carbon filter elements on their own. They need to be switched out far more frequently (every 26 gallons, or about two months) than the hollow fiber filter , which is good for 1,000 gallons.

The Larq Bottle Flip Top effectively reduces lead and some industrial compounds as well as chlorine, which is unusual for a filter bottle. Larq shares the test results (PDF) publicly, as we require. But it has a pop-up mouthpiece that’s always exposed to dirt and other schmutz. And the filter—which is necessarily denser in order to be more capable—takes more strength to suck water through than our top pick from Brita. Replacement filters are also expensive at about $15 to $20 every two months. A regular bottle filled from a filtered water source is a better option if you want extensive purification.

The Phillips GoZero Filtration Bottle is similar to our pick, the Brita Premium Filtering Water Bottle, in form and functionality, but its mouthpiece is shorter and harder to grip between your lips, so it’s more difficult to suck from.

The cleverly designed Grayl 24oz GeoPress Purifier is intended for camping and adventure travel, and we tested it largely to see if it might be a surprise winner for urban and suburban adventures, too. We found that it isn’t: Its plunger action, in which you fill the container and then force the filter through the water, requires a lot of strength and a location where you wouldn’t mind a few splashes. It would be a conversation starter in an office or classroom, but it belongs in the great outdoors.

It features a non-slip grip and reliable durability , so it's good for going on your rockiest and bumpiest excursions. You want peace of mind when it comes to bacterial and heavy metals, so this is our top option for every adventurer.

When testing this water bottle, we found the twist cap easy to use and the spout easy to drink from. We didn't notice any leaks , even on more intense hikes. We also love the handle, which makes this option very portable . Although it is heavier than others, since it comes with a water bottle filter, it still fits into the average backpack bottle pocket and standard cup holder.

Potential Flaws

• While this bottle may be more expensive than several alternatives on our list, we believe it justifies its cost for individuals who are dedicated hikers, frequent travelers, or daily adventurers, thanks to its reliability and durability.

• Seal 4.5 /5
• Portability 5 /5
• Insulation 5 /5
• Durability 4 /5

Enclosed straw

Double-wall insulated

Only recommended for travel and everyday use

Filter Type: Activated carbon | Material: Stainless steel | Weight: 14.4 ounces | Care: Hand wash | Volume: 20 fluid ounces | Filter Life: 40 gallons | Our Overall Rating: 4.6/5

Brita’s Stainless Steel Filtered Water Bottle is double-wall insulated to keep your water cold for over 24 hours for safe and satisfying hydration all day long. The activated carbon filter works to filter out contaminants like chlorine and certain particulates while preserving healthy minerals and electrolytes that may be found in tap water. 

When we tested the 20-ounce version of the water bottle , we found that its filtration system made tap water taste great. We also really like the water bottle's silicone mouthpiece and the button on the lid that can be easily opened for one-handed drinking. This bottle is great for everyday use because of its easy-to-hold handle, enclosed straw, and sleek design.

• We wouldn’t recommend taking this one on your next hike or backpacking trip because it doesn't filter out some dangerous contaminants in natural water sources, like rivers or streams.

Bonus Favorites

Although we didn't test the following filtered water bottles ourselves, we still think they're a solid buy after our expert interviews and thorough research. Each product has reliable filtration systems, added features, and prices comparable to the shoes that we personally tested.

Most Versatile

Lifestraw go water filter bottle.

Good brand ethics

Comes in many colors

Suitable for a variety of activities

Some users complain of leaking

Sawyer products squeeze water filtration system.

Very lightweight

Requires multiple parts

Filter Type: Hollow fiber membrane | Material: BPA-free plastic | Weight: 3 ounces | Care: Back flushing required | Volume: 32 fluid ounces | Filter Life: 540 gallons

Recommended by both of our outdoor gear experts as the best option for hiking, Sawyer's Squeeze Water Filtration System was an obvious addition to our list. Although it’s not technically a filtered  water bottle,  to use, you simply fill the included water pouch, screw on the filter, and squeeze the pouch to push the water through straight into your mouth (or a water bottle). It's a budget-friendly and lightweight option that's great for distance hikers, says outdoor gear expert Maggie Slepian .

According to the manufacturer, it protects against 99.99% of all bacteria (like salmonella and E.coli) and removes 99.99% of all protozoa (like giardia and cryptosporidia). Plus, it's easy to clean the entire system thanks to the included syringe. This option is a reliable way to ensure clean water on all hiking trips, from your local path to the Appalachian Trail.

• While lightweight, this system has many more parts than other bottle-only options on our list. Still, we think the included mesh bag makes for easy carry.

Best Budget

Philips active water bottle.

Squeeze bottle

Delivers great tasting water

Not suitable for freshwater sources

Filter Type: Activated carbon | Material: BPA-free plastic | Weight: 5.29 ounces | Care: Dishwasher safe when filter is removed | Volume: 20 fluid ounces | Filter Life: 52 gallons

Philips' GoZero Active Filtered Water Bottle is super budget-friendly without sacrificing quality. The bottle comes with an attachable blue fitness filter that improves the taste of tap water by reducing lead, pesticides, and chlorine. You can purchase a separate green adventure filter suitable for more heavy-duty use, which can filter viruses and bacteria. 

Made from BPA-free plastic, the easy-to-use squeeze bottle is leak-proof and sleek, making it a great option for everyday use, gym sessions, and other outdoor activities. A huge plus: it’s dishwasher safe for super convenient and low-maintenance use.

• This water bottle is primarily designed for the consumption of safe tap water and may not be equipped for advanced filtration from freshwater sources.

Best for Extreme Conditions

Grayl geopress water purifier.

Removes heavy metals

May be a little bulky

Filter Type: Activated carbon | Material: BPA-free plastic | Weight: 15.9 ounces | Care: Hand wash | Volume: 24 fluid ounces | Filter Life: 65 gallons

Grayl’s Geopress Bottle is the perfect companion for hiking, backpacking, or camping. It’s built tough and made to withstand drops up to 10 feet , making it durable enough for the most extreme conditions. The reliable activated carbon filter removes waterborne pathogens , including Hepatitis A, E. Coli, Cholera, and more. It also filters particles (like sediment and microplastics) and many chemicals, heavy metals, and pesticides.

A fan of the water bottle, Slepian says it's simple to use: The filter screws onto the bottom, and then you push a plunger, and it filters the water. This removes the little floaties in water, so it’s great for collecting water from outside sources. Just fill it, press, and you’ll have 24 fluid ounces of safe, clean water in eight seconds. The BPA-free plastic bottle exceeds agency standards, making it a super reliable choice for your most extreme adventures.  

• This bottle is slightly larger and bulkier than other options on our list, but that's because it boasts a heavy-duty filter with maximum filtration capabilities.

Best Lightweight

Katadyn befree water filter.

Cap over mouthpiece to keep clean

Some complain of pinhole leaks

Filter Type: Hollow fiber membrane | Material: BPA-free thermoplastic polyurethane | Weight: 2.3 ounces | Care: Hand wash | Volume: 33.8 fluid ounces | Filter Life: 264.2 gallons

Katadyn's BeFree Bottle collapses down to fit into the tightest and smallest spaces, making it an obvious choice for our best lightweight pick. Instead of a traditional water bottle cdesign, this filter holds water in a soft flask pack that can be easily conformed to fit into any backpack, luggage, or purse.

We love that its hollow microfilter is tested to protect against harmful organisms, protozoa, and bacteria to surpass EPA standards. This bottle is best for outdoor activities, like backpacking and hiking, because it is so compact and provides quick hydration in less than one minute.

• Since this bottle holds water in a soft flask pack, it may be more susceptible to tears and leaks in extreme conditions.

Best for Outdoor Activities

Survimate filtered water bottle.

Has a compass feature

Leak-proof design

Straw may be difficult to use

Filter Type: Hollow fiber membrane and activated carbon | Material: BPA-free plastic | Weight: 9.6 ounces | Care: Hand wash | Volume: 22 fluid ounces | Filter Life: 396 Gallons

SurviMate Filtered Water Bottle is perfect for various outdoor adventures like biking , hiking, camping, and backpacking. It’s also great for recreational activities, from fly fishing in Rock Creek to playing defense in your local soccer game and everything in between. 

You can fill it with water from ponds, puddles, and more—while protecting against 99.99% of common bacteria (like E. coli), heavy metal ions, chlorine , and other organic contaminants. The BPA-free bottle is also super lightweight and comes with a carabiner clip to be effortlessly taken with you on all outdoor experiences.

• Since this straw is designed to flip up, using it with just one hand might be a bit more challenging. However, the upside is that it helps maintain cleanliness.

What to Look for When Shopping for Filtered Water Bottles

• Type of Filter: Different types of filters will filter out different things, outdoor gear expert Wesley Trimble says. Make sure you take a look at what type of filter comes with the water bottle you're purchasing and that it aligns with your intended use. Membrane microfilters typically remove bacteria, parasites, and microplastics, whereas activated carbon filters work to reduce chlorine and improve taste. A hollow fiber membrane filter is a fine filter that often removes bacteria like E.coli and protozoa, like giardia. And you can sometimes find a combination of two filters within one bottle that work together for optimal filtration.
• Material: Filtered water bottles come in different types of materials—the most common being plastic and metal. When considering which material to choose, it is completely up to personal preference and intended use, as different materials will be better suited for different types of activities. If you choose plastic, make sure it's free of toxic substances like BPA. Metal water bottles tend to be insulated and will keep your water cooler, but may be bulkier and heavier than plastic bottles, Trimble says.
• Size and Weight: Similarly to the material of your filtered water bottle, size and weight are up to personal preference and the type of adventure you’re taking. Filtered water bottles come in various sizes and weights, and the right choice for you will depend on your intended use. If you’re planning on packing a water bottle in your luggage to travel internationally, you may want to consider a smaller and more lightweight option. Whereas if you expect to carry your bottle to the gym every day or are hoping to use it while sweating it out on the elliptical machine , size and weight may not matter as much. 
• Price: As our list of top picks demonstrates, filtered water bottles come in various prices, and you’ll need to determine what price works best for your budget. However, Slepian believes this kind of equipment is worth spending a bit of your budget on since it ensures safe drinking water wherever you are.

How We Selected and Tested the Filtered Water Bottles

To find the best filtered water bottles, we've researched dozens and tested two options from top, trusted outdoor gear brands. For products we select through research, we first ask our experts what key features to look for in filtered water bottles. Then, we consider expert recommendations and review key specs to narrow down our list. Finally, we tested our top two options in the Verywell Testing Lab, evaluating each one based on the following key categories:

• Drinkability: If your filtered water bottle is difficult to use and produces poor-tasting water, you won't want to drink from it. First up, we test each bottle's drinkability: How easy is it to open the cap and take a sip? Does the water taste metallic, acidic, or grainy? We prioritize bottles that are efficient to use and deliver good-tasting water.
• Seal: Your bottle must be leak-proof, especially if you plan to take it on long hikes or traveling. To test each bottle's seal, we fill it with water, shake it around, and hold it upside down for one minute. We also throw it into a backpack and walk around for at least five minutes. If any water leaked out, we gave the bottle a poor score for this category.
• Portability: Next, we note any portability features, such as carrying handles, non-slip grips, or included bags. We also consider how lightweight the bottle is when completely filled with water and if it would be suitable for long hikes, travel, and more. Finally, we check whether the filled bottle fits into a standard car cup holder and backpack.
• Insulation: We also perform a cold liquid performance test: Using a thermometer, we record the water temperature inside each bottle. Then, we leave the bottle on a window sill in direct sunlight and subsequently re-record the water temperature at the three and six-hour marks. We prioritize bottles that keep our water cold for up to six hours.
• Durability: Our final test is for durability. We drop each bottle at least three times from table height, both lid-first and bottom-first. We note if the bottle is still usable and if there are any noticeable dents, cracks, or other damage. We give high scores to bottles that hold up perfectly after the durability test and throughout the entire testing period.
• Value: When the testing period is complete, we look at each bottle's price. Given how the product performed in each of the above-tested categories, we consider whether it's fairly priced. We only include bottles that we think are worth the money or that we would consider paying even more for.

We spoke to experts at every stage of our research, testing, and reporting for this story. These outdoor gear experts helped us learn more about the importance of safe drinking water and what key features to look for and avoid in a filtered water bottle. They also helped inform our test. We choose products independently but use expert input to influence our choices.

Why should I use a filtered water bottle?

You should use a filtered water bottle to ensure you stay hydrated by drinking clean water wherever your next adventure takes you. These handy bottles eliminate harmful bacteria, viruses, debris, and often heavy metals from any suspicious water sources.

Is filtered water really better for you?

If you plan on drinking municipal water from a new place or natural water from rivers, streams, lakes, and more, filtered water is always better for you. Filtered water bottles may remove harmful chemicals, bacteria, viruses, heavy metals, and more—turning any source into drinkable and safe water. 

Can filtered water bottles remove heavy metals?

It’s important to remember that not all filtered water bottles can remove heavy metals. If you know you will be traveling somewhere where heavy metals pollute the drinking water, look for a specific tested and certified filter to remove these contaminants.

Are filtered water bottles dishwasher safe?

Before purchasing a new filtered water bottle, check the manufacturer's website for suggested care instructions. Some bottles are dishwasher safe, while others require a bit more effort to clean. Maintenance is an important factor to consider when choosing which bottle is right for you, Trimble says.

How to Choose the Best Water Filter Bottler for Traveling

If you’re an avid traveler, you must’ve known how a good water filter bottle for traveling is an important item in your adventure gear. But what are the things that make water filter bottles a good one? These are the most important things you should consider beforehand:

Quality – Low, Medium, High

Different water filter bottles have different ranges of quality. Low quality filtered water bottles generally eliminate harmless minerals to improve the taste, which is not really the best choice if you’re traveling to somewhere new and foreign. Filtered water bottles with medium quality improve water quality by removing particles, bacteria, protozoa, and parasites. High quality filtered water bottles or water purifier also feature a technology that removes virus from any source of water.

Construction

Decent construction of a water filter bottle for traveling will contribute to its durability. Some of them are made from flexible plastics which are very light, which means you’ll save weight and space. But unfortunately, they won’t stay with you for long. Instead, you can invest in metal water filter bottles, although they’re not as popular and as cheap as the plastic counterpart, it’s a reasonable choice to invest in these bottles if you love traveling.

Types of filter

Generally, water filter bottles are equipped with either one of the available 4 types of filters; straw, gravity, squeeze and pump . If you’re looking for a type with a very small effort to filter the water, the gravity filter relies only on gravity. You just need to leave the water to drip through the filter on its own accord. This may take longer to process but it allows you to filter large amounts of water with the most minimal effort.

The straw filter works by sucking on the mouthpiece and the water is filtered through the straw on its way up. While the squeeze filter works pretty similarly to the gravity filter, you have to squeeze the water through them instead of relying on gravity to do all the job. Last but not least, pump filters require a different amount of effort depending on the model.

How do you filter water when traveling?

As we have mentioned above, the filtering happens through different processes depending on the water filter type. Many travelers prefer to take filtered water bottles with them because there are countries where tap water isn’t safe to drink. Besides, you’re saving your traveling budget and keeping things environment-friendly without having to buy plastic water bottles.

Do water bottle filters work?

Yes, they do! Generally, the main function is to ‘clean’ water from any water source to make it drinkable, safe, and taste better. Some of these brands claimed that their products went through a lab test. But given the number of globetrotters vouching for water filter bottler for traveling that actually works, it’s safe to say that water bottle filters DO work.

Why You Should Travel with a Water Bottle?

So, before we get into the deet on the best water bottles for travel, let’s learn more about why you should have one first.

Anyone who travels to oceanfront destinations has probably seen the horrific amount of plastic that wipes up onshore and floats through the water. 100,000 animals die every year by eating or becoming entangled in plastic.

The worst part? It will take lifetimes for this plastic to decompose, if it doesn’t end up in our food cycle first (through marine animals and sea salt) as broken down micro-plastic.

It’s not just the undegradable plastic that affects our planet. According to the Pacific Institute’s “Fact Sheet: Bottled Water and Energy,” the process of actually making the one-use plastic bottles use 17 million barrels of oil annually in the US alone, and that’s not even including the oil used for transporting the bottles.

Here’s the good news: there are a ton of efficient ways to reduce your carbon footprint and plastic waste consumption when traveling. One of the easiest and most effective ways to travel sustainably is to avoid single-use plastic the road, and  bring your own reusable water bottle!

Fight the fight against one-use plastic. Bring a reusable, fold-up bag for your groceries, a water bottle for your thirst, and sustainable straw for your iced coffee frappes. Maybe pack a reusable sandwich/food bag too!

We know it’s not always possible to forego plastic, especially when you are traveling, but none of these things will take up much room in your backpack. If we all make a conscious effort to travel sustainability, it will make a world of difference to the environment we aim to explore.

So without further adieu, I have listed the best water bottles for traveling below.

Should you purchase a stainless steel water bottle or a plastic one? What gadgets can you live without? Should you get a built-in purifier? All of these questions and more will be answered below!

For those who want something easy, affordable, and can take a beat. Extra insulation will also help keep your liquids hot or cold in more demanding climates.

  Hydro Flask  Water Bottle – Best Insulated Water Bottle

Founded in one of the outdoor capitals of the USA, Bend, Oregon, this is truly one of the best water bottle brands out there. I’m not kidding when I say that Hydroflask has a cult following either.

Why? Because their double-wall vacuum-insulated design will keep your water ice cold (or your tea/coffee steaming hot) for hours on end. I have left my ice water sitting there for days ( over 24 hours), and there have been ice cubes floating around.

This is the best water bottle in extreme weather conditions, like the mountains or desert. A buddy of mine works in the desert, and this is his go-to water bottle to keep him cool all day.

Moreover, they have tons of sizes ranging from 16 oz to 40 oz + with a variety of interchangeable caps and fun colors.

The wide opening has three lids – a flip lid with a loop, a flex cap with a larger loop, and a straw lid for convenience.

If you are buying a hydro flask water bottle for travel, I suggest sticking with a 24 oz size though. Frankly, the 32 oz + bottles are too heavy and bulky, though they make for a great weapon!

There are drawbacks to using a hydro flask for travel, however. They are heavy as well as one of the most expensive water bottles on the market, so it may not make sense to actually backpack with it.

Our team really love the Hydro Flask and feel it’s the best water bottle for travel for a few reasons. They basically told us it just ticks all the boxes, is it perfect, not quite, but it’s close! For a starters the bottle is super durable and the steel material used means there’s no plasticy taste. The team were also super impressed by how long this bottle kept their drinks either mega cold or burning hot even after hours on the trails.

Klean Kanteen – Runner-up for Best Stainless Steel Water Bottle

Dueling it out for the overall best water bottle is Klean Kantene…

Why do we love it? This water bottle is easy to fill, but the opening is narrow enough to drink from, without spilling all over yourself, even within a moving car 🙂

And speaking of cars, it also fits in most cup holders, but it’s wide enough insert ice cubes.

It’s also easy to clean, dishwasher safe, and leakproof, so you can keep it in your backpack without spilling.

It’s one of the most lightweight stainless steel water bottles on the market. Like the hydro flask below, the Klean Kantene has a number of different lids and colors, depending on your preference. I’m a big fan of the sports cap as pictured.

Our team felt this was a close second when it came to the best travel water bottles and it just narrowly missed out on the top spot. They were blown away by how long this bottle keeps drinks both hot and cold. They also felt it held up well to the rigours of travel, non of our team members reported paint chips or dints even after a few months of usage.

Note: Make sure to read our guide on  how to travel responsibly, ethically, and sustainably   as well as how to  reduce your plastic footprint !

For those who are traveling to places with less-then-ideal sanitation standards and don’t want to bother with conventional means of purification i.e. chlorine pills, Steripens, awkward Lifestraws.

Grayl GEOPRESS Water Purifier Bottle – Best Water Bottle with Filter for Travel

What’s better than a travel water bottle you can fill with purified water? A travel water bottle you can fill with any water.

So, the Grayl GEOPRESS is not quite a water filter bottle. I mean, it is; you’re not going to accidentally contract giardia because of my wishy-washy banter. But it’s just not as boring as a standard filter bottle – this thing purifies .

You’ve got three parts: the outie, the innie, and the filter. You fill the outie with toxic death-infested water, push the filter through, and sunshine-lollipop water runs into the innie. Think of it like the AeroPress of water purification!

You know what I call that?

That’s science!

So what about the deetz? Well, this filtered water bottle carries 24oz of liquid (710mL for all my metric bros) and weighs 15.9oz (450g). Obviously, that’s before you put the protozoa-free water inside. The Grayl GEOPRESS is also one hardass son-of-a-bitch and will survive some pretty decent drops.

Of course, that’s not your burning question, is it? The burning question is ‘Does it work?’

The answer: yes indeedy! We thouroughly tested the Grayl GEOPRESS water bottle (not least to mention trekking in the Karakoram in Pakistan) and we’re happy to report: no violent illnesses! All our body fluids stayed right where they’re meant too.

In all seriousness, this things trumps other standard water filter bottles because it removes everything . Bacteria, parasites, viruses, heavy metals… no other filter water bottle offers the coverage and peace of mind that the Grayl GEOPRESS does.

Our team felt the Grayl was the best water bottle for traveling abroad due to just how well this bottle gets rid of any nasties. The team also felt the bottle was very well made and many of them have personally had this bottle for years and they’re still going strong. They also felt the mechanism and changing of the filters were super easy.

And that’s why it’s The Broke Backpacker’s official choice for the best travel filter water bottle. Enjoy all that death-free water!

LifeStraw Water Bottle – Runner-Up Travel Filter Water Bottle

This was originally our top pick for the best travel filter water bottle but then the Grayl GEOPRESS came along and ruined LifeStraw’s day. That’s ok, LifeStraw; we still love you. Number two is still pretty darn good.

This reusable, BPA-free plastic water bottle filters water while drinking via a 2-stage activated carbon filter that removes bacteria and protozoa as well as reduces odor and chlorine.

The straw removes 99.9999% waterborne bacteria and 99.9% waterborne protozoan parasites without chemicals, iodine, or batteries.

This water bottle is leak-proof with a food-grade silicone mouthpiece. It comes in a 23 oz water bottle size.

Do not fret if you are looking at purchasing a water bottle that doesn’t purify water abroad. I travel with my Grayl Geopress , which ends up being more versatile since I can purify multiple water bottles and it also kills viruses.

Our team are big fans of the LifeStraw water bottle and love the additional features built-in including the carabineer attachment which makes it easy to keep on hand even if your pack doesn’t have a bottle holder. They also felt the filtration of the water not only made it safe but made it taste a lot nicer too.

LifeStraw also makes a separate straw that you can stand alone that I have heard great things about.

CamelBAK Fit Cap 32oz – Best Stainless Steel Water Bottle

The CamelBAK Fit Cap 32oz Water Bottle, fabricated from vacuum-insulated stainless steel, guarantees your beverages remain chilled for up to 24 hours or warmed for a maximum of 6 hours. It serves as an ideal mate for numerous outdoor excursions, gym workouts, or simply as a desktop companion at your workplace. Its leak-proof cap safeguards against accidental spills, while the design comfortably accommodates most cup holders and backpack pockets.

Furthermore, in a world growing more conscious of environmental conservation, the CamelBak Fit Cap Water Bottle stands out as a sustainable substitute for single-use plastic bottles. Thanks to its durable build, it can endure daily usage, promising longevity. The sleek design, combined with the practicality of the cap, establishes this water bottle as a prime selection for those leading an active lifestyle and who appreciate a perfect blend of utility and aesthetic appeal.

HydraPak SkyFlask 500 Water Bottle – Best Collapsible Water Bottle for Travel

This silicone-based collapsible water bottle is fantastic for those traveling with minimal space, yet still, want to bring a sustainable water bottle on their adventure!

The HydraPak water bottle’s major draw is its ability to roll into the size of a fist and lightweight material.

It’s the lightest reusable water bottle on this list, weighing just 4.8 oz! This is great for travelers with a carry-on.

The downside to this water bottle is durability. It’s not going to last you as long as a stainless steel bottle or even durable plastic.

Furthermore, for better or worst, this water bottle only comes in one size, 20 ounces, but it’s a small drawback if you want a lightweight water bottle.

Our team really loved how lightweight these bottles were and how small they folded up when not in use. They might be a little flimsy in the hand but for those looking for something super light and minimalist without being over-complicated, our team felt these were a great solution. They also loved that they were dishwasher safe so they’re really easy to clean.

HydraPak Flux 1.5 L Collapsible Water Bottle – The Best Collapsible Water Bottle with Filter

The HydraPak Flux is an ingenious piece of kit that combines the portability of a collapsible bottle and the utility of a filtered travel water bottle! It’s easy to use, easy to pack, easy to clean, and crucially effective.

The HydraPak Flux is most effective against bacteria and protozoa, killing over 99% of the little guys. On the other hand, there seems to be no definite word about the bottle effectiveness against viruses.

given that it’s a squeeze bottle, the HydraPak Flux actually has a pretty good flow rate. The flow won’t be anything like using a GRAYL post-purification but it will be damn sure better than using something like a Lifestraw, which requires iron lungs sometimes.

Note that the HydraPak Flux Water Filter itself is not compatible with other squeeze bottle brands.

Our team really loved the idea behind this bottle and its functionality. They felt it really cornered a great niche with the fact that it can easily be folded down and used as an emergency water bottle with its ability to be filled up with liquid like river water or other questionable sources! It might not be durable to use as your everyday bottle but our team swear by it for trekking in the wilds.

This light, collapsible water bottle from Generation Nomad stands upright on flat surfaces, ensuring stability no matter where your adventures take you. Whether you’re hiking, sightseeing, or commuting, this bottle is designed to keep up with your active lifestyle. It combines functionality, portability, and style in one sleek package.

With our collapsible water bottle, you can quench your thirst for adventure without sacrificing precious packing space and without adding any extra trail weight. All in, we are very impressed and it only costs £28.00.

For those who are open to using a plastic water bottle for travel just so long as it comes from recycled materials.

Nalgen REI Co-op – Best Reusable Water Bottle (Plastic)

REI Co-op Nalgene is one of the most prolific resuable water bottle brands out there today! Often used by thru-hikers and long-term backpackers because they’re the most lightweight water bottles on this list (that isn’t collapsible).

Furthermore, the wide mouth allows for easy cleaning on the road even though it is made out of plastic. They are definitely convenient as they can be used for any type of activity, and they can handle drops and bangs in rough terrain.

The downside of a Nalgene water bottle, however, is that you need to clean it quite often. The O-ring on the cap is made firmly and can be tough to remove, but this part needs to be cleaned most to avoid bacteria.

Nalgenes do not handle direct sunlight and extreme external temperatures well, so keep them away from concentrated heat to avoid activation of chemicals found in plastic.

This is a plastic water bottle, and although it is BPA-free, it could still be manufactured with chemicals in it… Make sure to wash the water bottle by hand before use, and avoid dishwashers and strong detergents.

This is our most affordable water bottle on this list, a huge plus for water bottles for travel, but it isn’t as durable as our insulated options.

Our team felt this was a solid option for those who wanted something simple, effective, light and easy to clean. Something that ticks all the basic needs of a bottle without being overly expensive or complicated. It’s also super durable and great for daily use both on your trip, at the gym or at work.

Now, you  could spend a fat chunk of $$$ on the WRONG present for someone. Wrong size hiking boots, wrong fit backpack, wrong shape sleeping bag… As any adventurer will tell you, gear is a personal choice.

So give the adventurer in your life the gift of convenience: buy them an REI Co-op gift card!  REI is The Broke Backpacker’s retailer of choice for ALL things outdoors, and an REI gift card is the perfect present you can buy from them. And then you won’t have to keep the receipt. 😉

Gone are the days a water bottle was simply a water bottle. As with anything in this day and age, you have unlimited options and vendors to buy from, and I’m going to help you narrow it down! Below are the top things to consider before you buy a travel water bottle.

1. Material

Most sustainable water bottles are made from glass, plastic, or stainless steel. Below I have provided quick summaries on why you should choose one material over the other…

Stainless Steel Bottles

These water bottles are the most durable, and most likely to last for the duration of your entire trip, whether it’s a quick vacation or multi-year adventure.

I’m a big fan of stainless steel water bottles because they last forever, and withhold insulation so your water stays cold (or hot) longer. Moreover, stainless steel water bottles are easy to clean, which is essential when you’re hopping from place to place. If I had to choose, stainless steel material makes for the best travel water bottle.

Reusable Plastic Water Bottles

Reusable plastic water bottles are the most common type of reusable water bottle on the trails because they’re the lightest and cheapest option. Many hikers choose to use a Nalgene or Camelbak  BPA-free plastic water bottle since stainless steel is heavier.

The downside to plastic is that they do not offer any insulation, so when you’re out for the day or exposed to the sun, your water will warm up quickly.

You have to clean plastic water bottles much more frequently, as they tend to get pretty nasty – think mold and odors – quickly, but the good news is wide mouth plastic water bottles are the easiest to clean.

If you buy a reusable plastic water bottle, make sure it is BPA-free, though pretty much all bottles come this way now. It’s always recommended to check that your purchase is chemical-free.

Check out the best CamelBak gear if you’re looking for some inspiration for your hydration!

Glass Water Bottles

Glass water bottles are great for having a reusable water bottle at home or the office, but I wouldn’t suggest one for traveling. They do not last as long, and they tend to be heavier. Plus, you run the risk of breaking it.

Silicone Water Bottles

Much less common, silicone water bottles are used for collapsible, travel-specific water bottles often sold on Amazon. They are a great addition to any backpacker’s packing list.

2. Water Bottle Weight and Capacity

Weight and capacity might be the most important thing to consider when you are choosing a water bottle for traveling. Backpackers, hikers, and trekkers will want to keep their backpack as light as possible. A travel size water bottle might be better than your standard bottle size if you want to keep things super light.

If you are already traveling with a tent and other camping supplies, you don’t want to add to the weight. Along with material, the best way to keep this weight down is by capacity/size.

I have found that when I am traveling a 750 ml (25 oz) sized water bottle is plenty big. Even if you drink water like a fish, it’s worth refilling your bottle more frequently than lugging around a 2-pound fire hydrant as a water bottle. Trust me, I am speaking from experience here!

3. Mouth Opening on a Reusable Water Bottle

Have you ever spilt water all over yourself when the driver halts to an unexpected stop? Imagine trying to take a sip of water on the bumpy back roads of India or Central America.

The wider the water bottle mouth, the more likely you are to spill while moving. That said, you definitely want the mouth wide enough to clean easily, and add ice cubes, fruit slices, etc.

4. Type of Mouth Opening – Sippers, Straws, Caps, etc.

Straws and sippers make it easy to drink on the go without spilling all over yourself (see the previous section), though they need to be cleaned more often. Personally, I prefer a straw typed mouth opening for my larger water bottle, but a normal-sized mouth opening for my 750ml and underwater bottles. Many water bottles will offer multiple choices to switch out.

5. Price for a Travel Water Bottle

Price is, of course, an important consideration with any purchase, especially for travel-related purchases. On one hand, you want a durable and high-quality water bottle. Price will often reflect this, but not always. Just because it’s more expensive doesn’t necessarily mean it’s better.

Secondly, you are traveling, and it’s best to not bring anything too expensive on your trip. I know, we’re talking about water bottles right, but I had my hydro flask water bottle stolen while I was traveling – and it stung a little more than it should have.

All of the water bottles we cover below are sold at a justifiable price point!

6. Filters and Purifiers

A filter or purifier might be essential if you are traveling to places where drinking water is unsafe. This can include developing countries or anywhere giardia can be contracted.

The important thing to keep in mind is that a filter only deals with bacteria and protozoan cysts; whereas, a purifier also neutralizes viruses.

If you are traveling internationally a purifier is a solid investment. A travel water bottle may come with a purifier, which makes them an excellent choice for travel.

However, you can also buy a separate purifier, like a Grayl Geopress , that can be used in any  water bottle. This is totally up to personal preference, but I lean towards having a separate purifier.

7. Insulated or Non-insulated

Insulated water bottles will obviously dictate the material the bottle is made of. Also known as double-walled, insulated water bottles will help you keep your drink hot or cold for hours on end, but this means the water bottle will be heavier and more expensive than non-insulated water bottles. If you’re looking for something dedicated to keeping your tea or coffee warm on cold-weather hikes, then a travelling flask might be another option.

Testing out a water bottle is hardly rocket science right? Nevertheless when we compared these H2O receptacles using a few set metrics to bring you the best water bottle for travel everrrr!

If a water bottle already feels heavy when there’s nothing in it, then just imagine how much of a pain in the arse it’s going to be once full! No one wants to be carting around extra weight on their backs so when it came to rating the best travel water bottle, the lighter the better!

Nothing beats the thirst-quenching satisfaction of cold water on a sizzling day. So we judged each bottle by its ability to keep water as cool as possible.

Cleanability

Water bottles get seriously grimy over time and keeping on top of this can be challenging. So we judged these travel water bottles harshly when it came to those that were difficult to keep clean. We tested this by literally getting our hands dirty and seeing how easy the cleaning process was and how much dirt each one had collected.

Still have some questions about the best water bottles for travel? No problem! We’ve listed and answered the most commonly asked questions below. Here’s what people usually want to know:

Why should you travel with a water bottle?

Simple: to save the planet! There’s enough plastic floating around in the ocean. If you can reduce that number by getting your hands on a travel water bottle, the planet will be forever grateful.

Should I get a filtered water bottle?

Yes, definitely. It’s always a good idea to have a filtered water bottle, like the Grayl GEOPRESS Purifier Bottle for example. Filtered water is super safe to drink and your body will thank you.

What is the best overall travel bottle?

We personally love the Hydro Flask , simply because of the value you’re getting. It’s a reliable brand, it’s got some great insulaton and you can carry up to 1L around. Perfect for backpackers!

What is a good foldable water bottle?

The Baiji Water Bottle is totally collapsible, making it super easy to carry. You can roll it up and store it in your pocket. The Katadyn BeFree is another great option and even comes with a filter.

1,000,000 plastic water bottles are sold every minute!  That plastic ends up in the ocean, which then leads to uneccesary loss of marine animal life .

And the travel industry contributes a staggering amount of waste and carbon emission on this planet, but here at the Broke Backpacker we truly believe that traveling on a budget and traveling sustainably can and should coincide.

One simple solution to traveling green while saving a few bucks every day (an amount that adds up for long-term backpackers) is to carry a sustainable water bottle at all times.

Frankly, using one-time-use plastic water bottles does not mean you are drinking higher quality water anyway as the plastic does eventually break down in the water you are drinking. They found that 93% of bottled water shows signs of  micro-plastic contamination . Most well-known brands made the list. I have also read that some brands have been caught using tap water…

Those $2 water purchases definitely add up, whether at home or on the road. That’s why the topic of travel water bottles is so important to us.

We want to save this planet and save your budget. This guide covers our top picks for water bottles for traveling. Our overall favorite water bottle is the Grayl Geopress because of its design, insulation, versatility, and price point. You really can’t go wrong with this sleek water bottle.

I’m also a fan of the Grayl GEOPRESS water purifier for visiting countries where the tap water is contaminated.

If we missed one of your favorite water bottles for travel, let us know in the comments!

Thanks for the recommendations! I’ve been travelling with a Camelbak Eddy for years, the same bottle and never had any issues with it. It’s funny how you grow attached to someone like a drink bottle travelling around the world with you. But anyway, recently it got taken off me at an airport. So time for a new travel bottle. Thanks again.

Got my first hydro flask from bottlecraze and I love this water bottle. Its just right for me. I take it everywhere I go. Its well designed and very insulated. I like it keeps my drinks cold all day.

Insulated water bottles are a game changer, right?!

Honestly, Avex water bottles are absolutely awesome and very, very, well designed. There are designed so well that Coleman borrowed thier design (licensing) and are now selling that same design under their branding. Why no one looks at this brand is beyond me. There are well priced too. Check them out on Amazon.

Nice! I will most definitely check them out 🙂

The Best Water Filters for Travel + Everything You Need to Know

Last updated: April 7, 2024 . Written by Laurence Norah - 12 Comments

If you are planning a trip or outdoor adventure to a destination where the local water might not be safe for drinking, you might be considering packing a water filter. This might be a backcountry camping trip, a hiking trip, or a trip overseas where you aren’t sure if the tap water is safe to drink.

Whatever the reason that you are thinking about packing a water filter, this post will help. We’re going to cover everything you need to know when it comes to choosing a water filter for travel, and also suggest the best water filters for your trip.

We’ll go over what a water filter is and why you might need one. We’ll look at what water filters actually remove from the water, and the different methods they use for doing so. We’ll cover a range of features that a water filter might have, and which ones you should consider important for your trip.

We’ve used a number of different water filters on our travels, both on camping trips in the back country and on trips to countries where the water wasn’t safe to drink.

We’ve put this guide together based on our personal experience as well as extensive research using information from trusted sources like government agencies.

By the end of this post, you should know if you need a water filter for your next trip, and if so, which one is going to meet your needs and budget!

Why You Might Need to Filter Your Water

Before we get into specific water filters, let’s look at why and where you might need to treat the water you are drinking.

As humans, we need water to survive. General guidelines are to drink 6 to 8 8oz glasses of water per day. The exact amount required varies depending on a range of factors, including ambient temperature and our level of physical activity. A lack of water can quickly become lethal, with most experts agreeing that the human body can only survive a few days without water.

So, we definitely need water. Unfortunately, water often contains things that are not good for us. These can include bacteria, viruses, and parasites as well as chemicals and metals.

Some of these may cause mild to moderate illnesses like travellers’ diarrhoea (or travelers’ diarrhea). This is actually the most common ailment travelers are likely to suffer from. Others can lead to very serious illness and even death. As such, it is important to ensure that the water you are exposed to is clean and free of any harmful contaminants.

This includes drinking water, and also the water you use for brushing your teeth, as ice in drinks, for cleaning fruits and vegetables, amongst other things. It only takes a small amount of contaminated water to cause a serious issue.

The main reasons people use water filtration devices are to filter potentially unsafe water for drinking, cooking, and personal hygiene. Common situations where you might need to filter water are as follows:

• When hiking, camping, fishing, boating, and backcountry travel where you may be drinking untreated water
• International travel to destinations with unsafe drinking water
• Situations, such as flooding or water treatment issues, that make home water supply unsafe
• As an environmentally-friendly alternative to buying and drinking bottled water
• To filter safe but bad tasting water

Now, there are a number of different ways that you can treat water, as outlined by the US Centers for Disease Control and Prevention here . These include boiling water, using chemical treatments, filtration methods, and the use of UV light. So you do need to make sure that you are using the best method based on the type of contaminant, the destination, and your travels.

We discuss all these methods in more detail in our guide to accessing   safe drinking water when traveling . That guide also covers things like how to know if you need to filter water, and where tap water is safe to drink. We would recommend reading that guide as well for a fuller understanding of the topic.

This guide will focus specifically on water filtration as a method for treating water. In this guide we will be primarily looking at water filters from a travel perspective, meaning devices that are designed to provide you with drinkable water on trips abroad, hiking, back country camping trips, etc.

What is Water Filtration?

Water filtration is a method of purifying water for drinking. In the case of water filtration for travel, the goal is to make it safe to drink. There are other water filters on the market, often marketed for in-home use, which are primarily designed to remove taste and odor from water, but those are not within the scope of this guide.

Water filtration devices are a popular option for making water safe to drink when traveling, with a number of options available on the market at varying price points. Water filtration works by passing the water to be treated through a fine filter. The filter pores are so fine that they remove many contaminants from the water, resulting in clear, drinkable water.

Generally, the size of the filter pores will determine which contaminants the filter is capable of removing. Filter pores of around 0.1 – 0.2 microns (100 or 200 nanometres) will filter protozoa and bacteria, but not viruses. To filter out viruses, the CDC recommends filtration pores smaller than 0.03 microns (30 nanometers).

There are other technologies that can be used as part of a water filter such as ion exchange technology which can also purify water of various contaminants. These usually work in combination with pore-based technology.

A good water filter will clearly list what it is capable of cleaning, and should also reference the certification standards it has met that allow it to make these claims. More on these standards later on in the post.

Some water filters also include a carbon filtration stage which is designed to remove bad tastes from the water.

Advantages and Disadvantages of Water Filters for Travel

A water filter can be a good option for travel, but it is not the only option.

Some of the advantages of water filtration over other water treatment methods include:

• They can filter lots of contaminants, including bacteria and protozoa. Some can also filter viruses.
• They can filter water in a shorter amount of time than most other methods – almost instantly in certain types of filters such as the straw ones
• They are able to remove cloudiness caused by dirt/silt/sand, producing clear drinking water
• They can enhance the taste of water with carbon filtration
• The filtration device also often acts as a drinking vessel and for water storage, meaning you can carry some water with you
• They do not require any sort of energy source to work, meaning they are effective even when off-grid
• They are a lightweight option compared to something like a camp stove
• Some filtration systems, particularly gravity-based filtration, are ideal for cleaning large amounts of water which is good for a group scenario

Some of the disadvantages of water filtration over other water treatment methods include:

• The upfront costs can be higher than some other methods, although over time this cost evens out
• Most systems have filters which need replacement, adding to the overall cost
• They are more bulky than some options such as chemical filtration tablets or drops
• Some effort/force is needed on some methods of filtration, including pump-based and straw-based filtration methods
• They are not as effective on certain types of contaminants as boiling

Overall, a water filter can be a great option, but it is not the only one. See more options in our guide to safe drinking water for travel .

What to Look for in a Travel Water Filter or Purifier

Before we go through some of our recommended water filters, we wanted to cover what you should be looking for in a water filtration device.

What can a Water Filter Remove?

Probably the most important question you need to ask when shopping for a water filter or purifier is what it is capable of removing from your water.

The main contaminants you are likely to want to remove from water are:

• Chemicals 
• Dirt / silt / sand
• Microplastics

While water filtration and water purification systems are able to remove the above types of contaminants, not all filtration systems are capable of removing all these contaminants from water. To choose the best water treatment method, you will want to consider where you are traveling and the sorts of water sources you are likely to have access to.

Most water filtrations systems can remove most dirt, sand, microplastics, bacteria, protozoa, and parasites from the water. However, only those with finer filters will be able to handle viruses as well. And only those with carbon filters will generally be able to remove chemicals affecting the taste or smell of the water.

For backcountry travel in the US for example, the more pressing concerns are protozoa and bacteria, which most water filters should be able to handle. Viruses are most commonly transmitted via human waste, and this transmission is far less common in the US due to good waste management practices and low population densities in the areas where travelers might need to filter water sources.

Travelers to developing parts of the world may also want to consider a water purification system that can also remove viruses. Of course, those of you wanting to err on the side of caution (not a bad thing), might want a full purification system regardless of destination.

What can’t a Water Filter Remove?

Water filters and water purifiers can’t remove every possible type of harmful contaminant from water. You will want to carefully read the specifications of a particular water filtration product to ensure it removes the contaminants of concern for you.

It is important to note that water filters are generally NOT capable of removing things like:

• Toxic chemicals
• Radioactive materials

In scenarios like this, which normally are disaster related, the CDC recommends using bottled water.

Water filters for travel are also not designed to desalinate or filter seawater or ocean water.

Water Filter vs Water Purifier

You may come across the term water filter and the term water purifier, and wonder what the difference is. The difference is normally down to what it removes from the water.

A water filter is normally capable of filtering out protozoa and bacteria, and has larger pore sizes in the filter mesh. A water purifier can also filter out protozoa and bacteria, but is additionally capable of filtering out viruses which are much smaller.

Travellers in the United States will normally be more concerned with bacteria and protozoa such as Giardia and Cryptosporidium , which can be filtered out with a water filter. Travelers to less developed nations will need to consider viral risks like hepatitis A, which require a purifier.

These two types of filtration products are normally grouped together and we will be covering both of these products in our guide.

What Filter Mechanism Does It Use?

Water filtration devices, as the name suggests, use a filter to clean the water. These filters are very fine, and the water normally needs some pressure in order to pass through the filter itself.

Different filter systems have adopted different approaches to this. Three common systems are straw-based, pump-based, and gravity-based.

A straw-based system works like a drinking straw. The filter is found inside a large drinking straw like device. You put one end of the straw in the water to be filtered, and suck on the other end. The action of sucking through the straw creates negative pressure which results in the water passing through the filter and into your mouth. This is a good option where you have regular access to water, but is best suited for single person use. It can also require quite a lot of effort to suck the water through the straw.

Examples of recommended straw-based filtration systems are the LifeStraw Go and Sawyer Bottle .

A pump-based system works using some kind of pump to exert pressure on the water and force it through the filter. This is a good option for filtering water for later use, and you can filter as much or as little water as required in the moment. The disadvantage is that it can require quite a lot of manual effort to filter the water.

Examples of popular pump-based filtration systems are the Survivor Filter Pro and Grayl UltraPress .

A gravity-based system uses gravity to force the water through the filter. You add the water to be filtered to a bag, hang it up somewhere with the filter at the bottom, and gravity causes the water to pass through the filter. This can take some time, and is more popular for larger amounts of water. This is a good option for a group camp or for RV use where you want to filter larger amounts of water for multiple people.

An example of a popular gravity-based filtration system is the LifeStraw Mission .

How Long Does It Take to Filter Water?

When evaluating a water filtration or purification system, you should investigate how long it takes to filter the water. In most cases, manufacturers should provide an estimate for how long it takes to filter a certain amount of water, say one litre or one gallon.

For example, a gravity or pump-based system might be capable of filtering 10 litres in one hour.

For a straw-based system, the speed will depend on how hard you suck on the straw. But filtration is fairly instantaneous.

How Easy is it to Use, Maintain, Clean and Store?

When it comes to a product that is designed to create safe drinking water, you ideally want it to be as easy to use as possible. We recommend looking at the instruction manual for any product to get a feel for how many steps are involved in producing clean water.

If a product has a complicated, multi-stage process, there is a higher likelihood that you are going to get something wrong, potentially leading to drinking contaminated water. Ideally, the process should be simple and easy to remember.

As well as ease of use, you will also want to consider how easy the product you choose is to maintain, clean, and store. It should be easy to take apart for any cleaning, and there should be guidelines on how best to store it between uses.

A water filter isn’t something you are likely to be using every day, so between trips you want to be sure it is something you can pack away for next time without worry.

How Much Water Can it Filter?

Most systems for water filtration and purification have a limit on how much water they can filter. Larger pore filters, such as those designed to remove bacteria and protozoa, tend to have a longer lifespan than those with smaller pores which are designed for viruses.

So for example, a purification filter that can filter out viruses might be able to do 100 – 400 litres before the filter needs replacing. A system for bacteria might be able to do 1000L+ before it needs replacing.

This is because the way the filters work is that they actually get blocked up by the stuff they are filtering out of the water. Over time, all the pores will be blocked and the filter will stop allowing water through. Smaller pores get blocked quicker than larger pores.

Some filter systems allow you to extend the life of the filter by “back-washing” them. This involves forcing purified water through the filter in reverse to clean it out. This can significantly extend the lifespan of the filter.

Some water filter systems have different filter stages as well. For example, there might be a pore-based filter for filtering out nasties, and a carbon-based filter for improving the taste. Often, the carbon-based filter will have a more limited lifespan. The good news is that a worn-out carbon filter doesn’t make the water less safe to drink, although the taste of the water might be degraded when it is worn out.

The main thing is to figure out how much water you are likely to need to filter on your trip, based on duration and number of people. Then you can see if the device you are choosing will be adequate, and if you might need to invest in additional filters.

How Durable Is It?

Depending on where you plan to use it, a water filtration system is likely to be a critically important part of your kit. Having access to clean water is really important, and you need to be able to rely on the product you are buying.

Ideally the product will have been tested to withstand a certain amount of impact, both empty and full. If it stores water, you want to be sure it’s not going to leak. Out on the trail, you want something that is going to be able to handle being dropped or bashed around a bit without failing.

Definitely be wary of anything that has small fiddly bits of plastic that might easily break, as this could cause a serious problem. We would normally recommend having a fall-back system, such as chemical purification tablets if you will be off-grid for a while, just in case.

How Much Does It Weigh?

Weight is an important consideration for any traveler. If you are planning a back country hiking trip where you are carrying everything on your back, then you will definitely be thinking about weight a great deal.

However, even travelers with checked luggage don’t have infinite luggage allowances! So you are unlikely to want to pack a big bulky water filtration system, or carry it with you when you are out sightseeing.

The good news is that many of the options on the market are lightweight and designed to be portable, often being not much larger or heavier than a normal water bottle.

Does it Have Replaceable Parts?

Different filter designs will likely have different parts that are replaceable, and it is worth understanding what these parts are and what the replacement costs are.

Most filter systems will have replaceable filters, but some may have additional elements like hoses or seals that you are able to replace.

When comparing prices of different systems, it is worth checking the different prices of these replacement parts and their estimated lifespan so you have an idea of a total lifetime cost.

Certification of Efficacy

For something as important as safe drinking water, it is not enough to believe a manufacturer’s claims of efficacy. Any producer of a water filtration or purification system that believes in their product should be willing to have it independently tested to an agreed standard. Ideally these tests will be provided in full for you to look at.

There are two main standards that are used for water purification / filtration testing. The first is the  EPA standard . This was developed by the US-based Environmental Protection Agency in the 1980s, and provided a framework for testing micro biological water purifiers in order to demonstrate if they produced water that was safe to drink.

A more recent testing framework, NSF P231 , was released by the international organisation NSF (this used to stand for National Sanitation Foundation, but today it is just called NSF). The NSF framework was developed based on the EPA document, but is regularly revised and updated.

NSF P231 is the standard you should be looking for as a minimum for filtration testing. It is a tough 10-day test in multiple parts, and a reputable manufacturer should be able to show evidence that their device passed the test in full.

It is worth noting that there is also an even more strict standard, NSF P248, which some brands also test to for extra peace of mind. This is similar to P231, but was developed for testing US military water purification systems for use on military operations. This one is less common for consumer-focused filters, but if you want the ultimate in peace of mind, consider investing in a product which has met P248 testing requirements.

Note that there are other NSF testing standards, including NSF 42 and 53. These are primarily designed to test home water filters for taste improvements, rather than to render them safe.

We would definitely recommend investing in a filter that meets EPA and NSF P231 testing standards, and which provides proof of the same.

Cost Per Litre / Gallon

When you are comparing different water filters and purifiers, it can be hard to get an idea of how they compare from a cost point of view.

One good way to compare is to see how much it would cost you to filter one litre or one gallon of water using the device. To do this, you just need the cost of the device and the amount of water it can filter over its lifetime.

For example, you might spend 100 dollars on a device that can filter 1,000 litres of water. 100 divided by 1,000 is 0.10. So this device would cost you 10 cents per litre.

Of course, if the device has a replaceable filter which costs 25 dollars, your future cost will drop. So over the total lifetime of the product your overall cost might be lower. However, calculating the initial cost per litre or per gallon is a good starting point for comparison purposes.

What Water Sources Does It Support?

Depending on the type of travel you are doing, you might need a different style of water filtration device. For example, if you are primarily travelling in a country where you just want to filter the tap water for safety, then most devices will work fine as you can just hold them under the tap.

However, if you are planning a back country trip that will require you to source water from a stream or river, then you will need a device that allows you to capture that water, especially if the source is shallow. This might involve tubing and a pump, or some other mechanism for capturing the water to be filtered.

The main thing is to pick a device that is capable of working in the various scenarios you will need to use it in.

What Temperatures Does It Work In?

It is really important to check what temperatures the device you plan to buy is capable of working in. This is especially the case if you are planning on traveling to a cold weather destination.

When the temperature dips below freezing, obviously this can cause any water inside your filtration system to freeze. Some filters will be permanently damaged if this happens, and so are not rated for use in freezing weather conditions.

Most devices will work fine in warm weather, although do always check what temperature range the device is rated for and compare it with the temperatures you expect to encounter when using it.

The Best Water Filters for Travel

We will now go through our pick of the best water filters for travel. We list products across a number of water capacity sizes and price points that will suit a variety of travelers’ needs. We include water filters and water purifiers that use each of the three primary filtration methods.

Before we do though, a quick note. We are not qualified water purification experts or medical professionals, and you should seek professional guidance as to the best water filter for your needs and specific situation. This article is for information purposes based on our experiences, and does not constitute health advice.

We would stress that water purification is a complex topic, and drinking water that is not properly treated can be life threatening. So please ensure you research the topic thoroughly, understand the risks for your needs and destination, and get qualified advice if you are unsure.

These products are grouped by filter type (straw, gravity and pump), and then approximately by price, although prices vary so do compare before making a decision.

LifeStraw Go

LifeStraw are a well-known brand in the world of water filtration. They make a range of products, some designed for large scale water filtration in developing countries, others that are focused on the needs of travelers specifically.

Our favourite LifeStraw product for general travel is the LifeStraw Go series. This has actually been through various iterations, and we have used both the older models and the newer models.

You can see the older model in purple in the image below for reference. This has been replaced with the newer models seen on the left and right.

The left hand model is a double walled insulated stainless version , whilst the right hand version is more of a direct replacement to the original as it’s made from plastic.

The main changes are the new straw which is covered by the lid when closed. This makes the product more sanitary and also reduces the change of leaks, but it is not marketed as being fully leak proof.

The new model is also available in a stainless steel insulated version . This has the advantage of keeping your liquids cooler, but does add significant weight. For comparison, the 1 litre plastic model weighs 268g / 9.5oz empty, whilst the 1 litre stainless steel model weighs 624g / 22oz empty.

For back country hiking and backpacking we think the plastic model makes more sense as it is significantly lighter. However, if you want to keep your liquids cool the stainless steel version will also likely be more durable, although we’ve not had any issues with our plastic version across multiple trips.

We’ve used our LifeStraw Go on back country hikes in the USA where there hasn’t been filtered tap water available, including on a multi-day hike to Havasu Falls in Arizona. We’ve also taken it on international trips to filter tap water where we weren’t confident it was safe to drink.

The LifeStraw Go is a combined water bottle and water filter. It uses a straw-based filter system. To use it, you fill the bottle with the water you want to filter. The lid has a removable large straw filter attached to it, and when you suck through the spout the action of sucking draws the water through the filter.

There’s are various sizes available, including a 650ml (22 fl oz) version and a 1 litre (34 fl oz) version , and the current model can be purchased in either a stainless steel or BPA free plastic version. You can also buy a straw standalone if you don’t want the bottle.

The product uses a 0.2 micron filter which is capable of filtering out bacteria and parasites, but not viruses. It can handle up to 4,000 litres (1,000 gallons) before the filter needs to be replaced.

It also has a carbon filter to improve the taste, however this is only good for 100 litres (26 gallons) before it needs to be replaced.

LifeStraw test all their products and publish their results on their website. The LifeStraw Go meets US EPA and NSF P231 drinking water standards for the removal of bacteria and parasites.

The main disadvantage of the LifeStraw is that it is really designed for single person use. The filtration happens as you drink, so you can’t filter water and then distribute it to others. So everyone would need their own LifeStraw. It also isn’t good for filtering water for uses other than drinking, for the same reason.

However, as a drinking water filter it works very well as long as you don’t need to remove viruses, and the price is also very reasonable. We still use ours regularly when we travel.

Other similar options on the market include the Sawyer Bottle and the Katadyn BeFree . These work in a similar way, so you might want to compare stats and prices to see which fits your needs best.

Capacity: 650ml / 22fl oz (larger 1 litre size also available) Weight:  221g / 7.84oz Filter type: Straw based What it can filter:  bacteria, parasites Lifespan: 4000 litre / 1000 gallon Cost per litre in USD at MSRP: 1.12 cent per litre Price: Check online at Amazon here , REI here

Sawyer Bottle

Sawyer are another well-known brand who make a variety of water filtration products. The Sawyer Bottle is similar to the LifeStraw Go in that it works with an inline straw. To use it, you simply fill up the water bottle, then drink through the inline straw.

The bottle uses Sawyers 0.1 micron filter technology, which means it filters out bacteria and parasites, but won’t remove viruses. As it’s a straw, you need to suck quite hard to get the water through.

One major advantage of the Sawyer Bottle compared to the LifeStraw Go is that it comes with a backwashing kit. This is basically a syringe that you can use to force clean water through the filter in reverse, a process known as backwashing.

This significantly extends the life of the filter because it unblocks the pores. Sawyer state that with regular backwashing (after every trip ideally), the filter should last for at least 100,000 gallons. That is basically a lifetime of use for most people, and it makes the Sawyer Bottle one of the most cost-effective water filters in our round up on a cost per litre basis.

The bottle itself is also relatively lightweight, at 5.5oz (155g), and can hold 34oz (1 litre) of water.

It has similar downsides to the LifeStraw Go, in that it is primarily designed for providing clean drinking water for one person, rather than water for multiple people or for other purposes like cooking.

It is also missing a charcoal filter, so does not remove the taste that filters with a charcoal filter do. Products are tested to EPA standards, with test reports available on their website here .

Note that if you are traveling light and want a super portable water filter, Sawyer also sells their filter in a straw format so you can just drink directly from a water source through the straw.

The Sawyer mini filter only weighs 2oz and lasts for 100,000 gallons, with the same filter performance as the bottle (essentially it’s the same filter just with a straw instead of a bottle). This is a great option if you just need a filter and don’t need a bottle, or will have regular access to a water supply.

Note that Sawyer filters are also made in the USA.

Capacity: 1 litre / 34oz Weight: 155g / 5.5 oz Filter type: Straw What it can filter:  bacteria, parasites Lifespan: 454,609 litres / 100,000 gallon Cost per litre in USD at MSRP:  0.01 cents per litre Price: Check online on Amazon here

Water-to-Go Bioplastic Bottle

Water-to-Go make a range of water filtration bottles, but the one I want to highlight in this post is their Water-to-Go Bioplastic bottle.

That’s because this bottle is one of the more sustainable bottles on the market, as the bottle itself is made from bioplastic. Specifically, the bottle itself (although not the filter) is made from a sugarcane byproduct and is 100% recyclable. You can read more about their eco-friendly plastic here .

It’s also dishwasher friendly (although the lid needs to be washed separately). The small size and weight also makes it great for travel.

Of course, green credentials are no good if the bottle itself isn’t capable and I’m pleased to report that is the case.

This bottle actually filters more than most other bottle filter systems. As well as the usual bacteria and parasites, it can also filter viruses. These claims have been tested and proven by independent laboratory tests in the UK, USA, India and China, and you can see details of those test results here .

The filtration is achieved with a combination of a fine filter mesh, activated carbon and electropositive nanofiltration. That means that as well as purifying the water, it also removes bad tastes, heavy metals, chlorine and PFAS.

Now, there are some downsides. All that filtration does reduce the water flow rate, so it does take a bit of effort to suck the water through the straw. In my testing it’s a pretty similar experience to the LifeStraw system, but with the advantage of filtering more.

The other downside is that filtering out things like viruses and other smaller particles means that the filters do not last as long compared to systems that only handle bacteria and parasites. So the initial cost in cents per litre is a little higher than those systems, although replacement filters are good value and will bring that cost down over the lifetime of the bottle.

Overall, if you are looking for a more eco-friendly water filtration bottle that can handle viruses as well as bacteria and parasites, this is definitely an option to consider.

Capacity: 550ml / 18.5fl oz Weight:  99g / 3.5oz Filter type: Straw based What it can filter:  bacteria, parasites, viruses Lifespan: 200 litre / 53 gallons Cost per litre in USD at MSRP: 28 cents per litre Price: Check online at Water-to-go here , Amazon here

LifeStraw Mission

If you are looking for a product that can filter water for a number of people as well as for multiple uses, then consider the LifeStraw Mission. This is a gravity bag with a built-in filter.

To use it, you fill the bag up with water to be filtered, hang it up, and then gravity forces water through the filter and out of the tap.

This makes the LifeStraw Mission ideal for camping in groups, as well as general activities where you need water for multiple people or uses.

LifeStraw actually make a range of gravity style filters. The Mission is the version designed to purify water, and it will remove bacteria, viruses and parasites. This higher level of filtration makes it a more expensive option.

It meets NSF standard P231, and LifeStraw publishes lab report data on their website for their products.

LifeStraw also have other gravity products, such as the LifeStraw Peak and Flex , which are lower cost options that remove bacteria and parasites but not viruses. So which is best for you will depend on your destination and requirements.

If you want purification that can handle viruses as well, then the Mission is a good option. It comes in two versions, one with a 12 litre (3.1 gallon) bag and one with a 5 litre (1.3 gallon) bag. They both have the same filter, which has an impressive lifetime filtration capacity of 18,000 litres (4,755 gallons).

It’s also relatively light at 530g (18.7 oz) for the 12-litre version, which makes this a good option for travel. Given the long lifetime of the filter, it also offers an excellent cost per litre.

Capacity: 12 litres / 3.1 gallons Weight: 530g / 18.7 oz Filter type: Gravity based filter What it can filter:  bacteria, parasites, viruses Lifespan: 18,000 litres / 4,755 gallon Cost per litre in USD at MSRP: 0.7 cents per litre Price: Check online on Amazon here and REI here

Grayl UltraPress

We came across the Grayl range of products when researching a trip to Africa. We didn’t want to have to be constantly buying bottled water, but knew that the risk of water borne viruses was a real concern. As such, we wanted a filtration system we could rely on to fully purify water for drinking.

In our case this was primarily going to be water sourced from taps, so whilst it was normally clear to the eye, we had no idea what it might be carrying. To be on the safe side, we figured a system that filtered out everything including viruses was a good idea, which meant our LifeStraw Go wasn’t going to cut it.

We found the Grayl UltraPress met our needs. This looks like a water bottle, but has a clever built in-filter system which has you pressing the filter through the water sort of like a French Press, with the clean water ending up in a chamber you can drink from.

There are a few advantages of the Grayl UltraPress. First, it is capable of filtering out all waterborne pathogens including viruses. It does this with a combination of small pore holes and electroadsorption / ion exchange. There is also a carbon element in the filter to remove taste and odor.

Second, the press system means that the purified water goes into a chamber from where it can be decanted into other containers. So you can use this for multiple people, for cooking, personal hygiene and so on. This makes it much more flexible compared to a straw-based system.

There are some downsides. The double-walled design and relatively large filter unit means that the device is a little heavy. It can also only hold 500 ml / 16.90z, although the larger GeoPress model holds 740 ml / 24oz

In addition, a filter which can filter out viruses often has a shorter lifecycle.

The Grayl Ultrapress filter is rated at 150 litres (40 gallons), so the cost per litre is quite high. In some destinations, it might even be higher than buying bottled water. However, replacement filters are not too expensive, so over the lifetime of the product the price per litre will come down a little.

The larger GeoPress is only marginally more expensive and can do up to 250 litres (65 gallons) per filter, so that does work out more cost-effective overall. However it is also bulkier and heavier.

Pressing the water also takes a bit of effort. I found it easiest to put the whole unit on the floor and then push down, although it can be done by hand on a table as well. Grayl does recommend using your body weight to push it down, and the surface of the top of the bottle that you push on is designed to be comfortable to do this and to withstand the pressure.

It’s just quite a bit of work, and in my experience took a little longer than the 10 seconds Grayl suggests, even with clean water and a new filter.

It is also worth noting that an electroadsorption / ion exchange based filtration process is a little different to standard filtration which relies on pore size. A pore-based system basically blocks the bad things. An ion based system works a bit like glue – the bad things in the water like viruses stick to the ions while the water passes through.

Unfortunately, over time, the ions can lose their charge and the filter can lose its effectiveness. Unlike a pore-based system, which blocks up and becomes un-usable when exhausted, there’s no easy way to tell when an ion-exchange system has lost its charge.

Grayl state that 300 presses is the lifetime of the system, and this is when the larger pores will become blocked, resulting in reduced flow. Basically, when it takes twice as long as normal to press through, it’s time to change the filter. We’d recommend trying to keep track of how much you have used it as well, and erring on the safe side when it comes to replacing the filter.

Finally, whilst the Grayl website states that the product has been independently tested to meet or exceed NSF protocols 42 and 53, there is no mention of NSF protocol P231, which is the standard that should be tested to. I also wasn’t able to find the test results on their website.

I did reach out to Grayl about this, and they did send through independent laboratory test reports that show that the product works as advertised to remove viruses, bacteria and protozoa. So if you have concerns, I’d suggest reaching out to them directly, their customer service is very responsive.

In addition, independent tests like this have shown that Grayl does purify water as it claims. I would like to see this sort of thing published on the Grayl website for transparency.

Overall we have liked our Grayl UltraPress for travel.

Capacity: 500 ml / 16.9 fl oz Weight: 354 g / 12.5 oz Filter type: Electroadsorptive ion exchange / charcoal What it can filter:  bacteria, parasites, viruses Lifespan: 150 litres / 40 gallons Flow Rate : 3 litres / minute Cost per litre in USD at MSRP: 60 cents per litre Price: Check online at Amazon here , REI here and Grayl here

Survivor Filter Pro

Survivor is another well-known brand for water filtration. The Survivor Filter Pro is popular with back country campers, but it’s a good travel option in general due to its light weight.

The Survivor Filter Pro is basically a hand powered pump filter. Unlike most of the other devices in our round-up, it doesn’t have built-in water storage. Like the SteriPen, it is designed to work with your existing water storage system.

The pump is quite simple. It has an inlet hose and an outlet hose, as well as three filter stages. You put the inlet hose into the water you want to purify, and the outlet hose into your container. When you pump, the water passes through the three-stage filter process.

These three stages work as follows. First, there’s a 0.1 micron (100 nanometer)  pre-filter which removes bacteria and parasites. The water then goes through the carbon filter, which improves taste and can remove certain heavy metals and chemicals.

Finally, the water passes through the 0.01 micron (10 nanometer) ultra-filter. 10 nanometers meets the CDC guidelines for optimal ultrafiltration of viruses.

You might think that having such fine pores would result in the Survivor Filter Pro having a short lifespan. However, Survivor supplies you with a syringe that can be used to force clean water through the pump in reverse. This flushes out the filters, unblocking the pores, and greatly extending the lifespan.

With regular back washing, Survivor states that their filters will last up to 100,000 litres (26,417 gallons) before needing to be replaced. Replacement filters are also relatively low cost. The carbon filter is rated up to 2,000 litres (528 gallons).

In terms of testing, all Survivor Filters are tested by independent third-party labs to be sure they perform as claimed up to NSF standards. You can see the reports on their website here .

In terms of cost per litre and overall unit cost, the Survivor Filter Pro offers excellent value for money. The only main downside is the flow rate. It takes a minute to pump half a litre of water. This is honestly to be expected, given the very tiny pore size in use, but it is definitely one of the slower options on our list.

If you don’t want to spend your time pumping, consider instead the battery powered electric version . That will filter up to 360 litres (95 gallons) from two AA batteries, but can also be powered by USB. Of course, relying on an electric solution will not be for everyone.

Overall, as a lightweight long-lasting option this is a very good choice. It’s particularly good for backcountry camping where weight is key, and where turgid water sources might stump a UV based system like the SteriPen. You also obviously need to pack and bring your own water bottle.

Capacity: N/A Weight: 362g / 12.8 oz Filter type: Pump based filter What it can filter:  bacteria, parasites, viruses Lifespan: 100,000 litre / 26,417 gallon Flow Rate :  0.5 litres / minute Cost per litre in USD at MSRP: 0.07 cents per litre Price: Check online on Amazon here

Hi Laurence & Jess,

So I am wondering if you could tell me about the Larq filter bottles – they say they “purify” the water but I can’t find that they work against viruses, protozoa, or anything like that. They do seem to work against bacteria and metals. Do you know more about these?

The Larq bottles and pitchers seem to be being promoted by other influencers a lot but seems they are getting them for free so don’t really trust their reviews and saw claim they do work against all the things that Sawyer and LifeStraw filter out but can’t find that info for myself on their website, so wanted to see what you know and think about them?

I am specifically looking for a good multipurpose filter bottle that I can use no matter where we go. we generally do 2 1 week long international trips each year as well as hiking/skiing trips domestically several times a year. Something that can filter out all the common baddies that can cause illness like bacteria, viruses, and protozoa as well as generally filter out sediment when drinking from backcountry sources when hiking. Not concerned about carbon filters for taste although fine if those included.

thanks for your help!

Laurence Norah says

5th September 2023 at 9:41 pm

This is a good question. So Larq has a few different products, and I should first say that I am not personally familiar with them. They do specifically say on their website here that the Larq Bottle Filtered is not designed for use in the backcountry (see the question about use in the backcountry), as it’s primarily designed to filter tap water of impurities rather than bacteria.

They also have the PureVis product, which works with a UV light to filter the water. That should be effective against bacteria and viruses in clear water, although any sediment can reduce the efficacy of a UV based system.

Honestly, it’s hard to give a good opinion without any personal experience. I would look for independent laboratory test results, which I can’t find for the PureVis on the site, and there’s limited information about what it works on. You might want to reach out to Larq directly to see if they can provide you with this information if you are interested in the product. I think to achieve what you want, you would need both the filtered bottle and the UV bottle.

Personally we do like our Grayl units which we’ve used across Europe and Africa with no problems to date. But I think that the majority of the products in our guide should work for you. The Survivor is one of the more lightweight options. I’d probably suggest picking a product that lets you filter water and decant it into other containers after filtering, so not a straw based system, as it’s a bit more convenient in our experience.

I hope this helps, let me know if you have any more questions 🙂

Hi Laurence!

QUESTION: So I use a pitcher water filter at home (LifeStraw or Brita) and mostly because I don’t like the way our local tap water tastes but am not going to pay for bottled water. So need a bottle for traveling that can filter basic things but also improves taste, what options would you recommend I look at? Ideally I would like something that I can use for places we are planning to go in future where water is potentially unsafe (e.g., Mexico/Carribean/Central America) but also use without a big filter just for taste filtration for tap water when traveling within the U.S. and Canada (so something with swappable filters if that is even a thing or maybe two different bottle types?). Thanks!!!!!!!!!!

17th August 2023 at 9:06 pm

Hey Ashlee!

So we have the home Lifestraw pitcher as well, it works pretty well although it is a bit slow 😉

Anyway to your question, the main part of the filter which improves taste is the carbon filter, so you’ll want a filter that includes that. I’d say the Grayl , Survivor , Lifesaver or Lifestraw .

Unfortunately none of them has the option to just use the carbon filter. I think if you are planning on sharing water with other members of your group then the Grayl, LifeSaver or Survivor would make more sense as the Lifestraw filters as you suck rather than allowing you to make water which you can put into other bottles for later use.

So then it will depend on which model you prefer. The Survivor is smaller and more portable, and you can even buy an electric version which makes things easier. The Grayl is larger and heavier, and the filters need replacing more often, but it definitely works well. The LifeSaver is also pretty heavy, and more expensive, but the filters last longer than the Grayl.

I hope this helps a bit! Safe travels 🙂

18th August 2023 at 12:55 am

thanks for your super quick answer, I think after looking over these we are between getting two Lifestraw bottles (since we already trust the brand and ok with the straw) or sharing a Grayl….will look closer and discuss with hubs and make the order this weekend. thanks a million for all your help!

18th August 2023 at 8:41 am

My pleasure Ashlee! Safe travels 🙂

Laurence & Jessica – very useful overview of all these types of water filters. It was helpful to read when planning for a trip we have planned to Mexico.

Another thing that has really concerned me is that microplastics are making it into our bodies via food and water and we now filter all the water we drink at home. It sounds like most (or maybe all?) of the water filters and purifiers you mention will filter out microplastics, am I understanding that correctly?

7th November 2022 at 10:52 am

You are correct! According to this Lifestraw article ( https://lifestraw.com/blogs/news/what-you-need-to-know-about-microplastics ), the smallest microplastics are around 0.7 microns, and all the filters in our list are around 0.2 or smaller, so they should all easily filter out microplastics.

Have a great time in Mexico!

6th September 2022 at 11:22 am

Hi there Laurence & Jessica,

So I have the regular Lifestraw from several years ago (no bottle) and it has been with me whenever I go on long hikes, boating, fishing trips, camping, etc. Generally just as a backup to the water we bring but we have used it a few times and no issues using it. We just collect some water using a cup or something and then use the straw.

I am thinking about getting the Lifestraw Go with bottle for more general travel purposes, but am wondering can it be used also just as a regular water bottle without the straw if in a place where we would not need to filter the water? Will it leak without a straw in it?

Best, Susan

6th September 2022 at 3:34 pm

So I just tested this with our Lifestraw Go bottle, removing the straw and filling it up with water. It doesn’t leak when I shook it around and held it upside down, or when drinking from it. The only thing to note is that obviously without the straw you have to tilt it to drink from it, whereas with the straw obviously the straw sucks from the bottom of the bottle.

I also don’t know as I haven’t tested it how it would perform on an airline – some water bottles with a flip up straw lid can leak a bit in a pressured environment, so I would just use it with caution in that scenario.

Otherwise I think it would definitely work fine as a regular water bottle, and it would also hold more water in that setup as the straw takes up a bit of volume.

Let me know if you have any more questions!

I’ve just ordered a Katadyn Befree filter… typical that you publish this now! Lots of positive reviews online so fingers crossed for it…

6th September 2022 at 10:35 am

I actually do mention the Katadyn BeFree in this guide under the LifeStraw entry. It’s very similar in terms of how it works, and Katadyn are a great brand too, so I don’t forsee you having any issues! I just felt the post might get a bit repetitive if I had so many overlapping products 😉

With what they’re charging for bottled water at the airport these days, nobody should be traveling without their own water bottle. However, it’s fair to be a bit wary of drinking from the tap, especially when you’re traveling to a place that doesn’t have a great reputation for clean water. This is why filtered water bottles make the most sense for travelers.

Filtered water bottles can be a little more expensive than regular reusable bottles and may involve a little more maintenance, but they’re worth it for the peace of mind you’ll have with every sip. Here are some of my favorite water bottles with filters for traveling.

If you’re the kind of person who would buy a filtered water bottle but never get around to changing the filters, a LARQ could be the bottle for you. Instead of filters, this bottle purifies water using a UV-LED light hidden in the cap. The light is powerful enough to kill germs, and the same kind of light is even used in hospitals to disinfect surfaces. The best part? It’s as easy to charge as your phone, with a universal charging port that will plug into any USB port.

Brita Filter Bottle

Fans of Brita, rejoice: You can take the 36387 Premium Water Filter Bottle on the road. The 26-ounce bottle is sleek enough to slip easily into car drink holders. The BPA-free hard plastic bottle has a carrying loop and an enclosed straw for ease of use. The chlorine-reducing filter improves the taste of tap water, and the filters are easy to replace.

8 Foods You Should Never Eat Before Flying

Glass isn’t necessarily travel-friendly, but at the same time, every drink tastes better when you’re drinking it from a glass. Why else would airlines go the extra mile to use them when serving their first-class customers? If you like glass but are worried about it breaking, check out The Escape , a glass water bottle that is protected by a silicone sleeve and uses a multi-stage filtration process to keep your water clean and tasting good.

GRAYL UltraPress Water Purifier

If you will be spending time outdoors and might need to drink from a fresh water source, consider the GRAYL UltraPress Water Purifier . With its press-down filter design, this travel water bottle can filter particulates as well as chemicals and waterborne pathogens without leaving an aftertaste.

LifeStraw Go

LifeStraw is one of the most trusted brands for water filters. Its LifeStraw Go bottle has a heavy-duty filter built-in, making it super easy to filter your water on the go. It is also available with a one- or two-stage filter, so you can choose the one that fits best for the trip you’re planning.

“The design of this product was not the challenge. The technology was the challenge, and technology is an essential part of the product,” explained Jean-Luc Madier, the director of engineering for LifeStraw . He’s referring to the company’s latest product, the Sip , a portable personal straw that filters 99.9% of the bacteria, parasites and microplastics in water. It lasts up to 1,000 liters (which they estimate is over a year of daily use), comes in cool colors, and costs $34.95 – a relatively small price to pay for peace of mind while on the road, or at home.

The LifeStraw Sip comes in seven colors, each with a coordinating carrying case.

While the Sip looks simple, it took seven years to nail down the integration of technology, engineering and design. “That was extremely long,” admits Madier. “We did a lot of different trials in our labs, where we can manipulate chemicals, bacteria, heavy metals and PFASs, but then we also sent the product for testing at external certified labs.” (Said data is available on LifeStraw’s website).

No batteries or electrical outlets required; simply sip through the straw, and the filter works its ... [+] magic.

In the end, the Sip had to filter water to the company’s specifications, and look like a straw. The resulting design – made of BPA-free, FDA-approved, premium stainless steel and silicone - is ten inches, a bit longer than what many may be used to, but the length was necessary to achieve the 99.9% level of filtration. “We could have made it bigger in diameter and shorter in length, but then it wouldn’t look like a straw,” noted Madier. “That was the compromise.”

LifeStraw, for the uninitiated, is a Climate Neutral Certified B Corp. borne of a partnership that its parent company, Vestergaard, forged with The Carter Center (a not-for-profit NGO founded by former U.S. president Jimmy Carter and his wife, Rosalyn) to eradicate Guinea worm disease. In the thirty years of their partnership, LifeStraw provided over 39 million Guinea worm-specific filters to those in affected areas to support eradication. The results speak for themselves: incidences of Guinea worm disease have been reduced from an estimated 3.5 million in 1986 to 14 in 2023, and the disease has been eliminated in 17 countries

The original LifeStraw Personal Water Filter was a similarly humanitarian pursuit: a straw that allowed users to safely drink from a pond or watering hole. That was twenty years ago. For about a decade afterwards, the company continued serving developing countries with various water filtering solutions and humanitarian efforts, including supporting the construction of a maternity ward at a health center in rural Kenya.

The original LifeStraw Personal – one that allowed users to safely drink from a pond or watering ... [+] hole — was introduced for humanitarian purposes in developing countries almost twenty years ago.

When LifeStraw finally made the personal straws available for the consumer market, they quickly became a favorite of outdoor enthusiasts, prompting a range of designs targeting that market, including a collapsible squeeze bottle .

LifeStraw quickly caught on with outdoor enthusiasts.

Launching a water bottle with that same filtering technology was a natural next step. LifeStraw Go, a refillable water bottle that incorporated the same technology as their straw, debuted just over ten years ago; an updated version was released last year. Today it is available in BPA-free plastic and stainless steel models in various sizes.

LifeStraw Go Series - a BPA free bottle with a microfilter that protects against Bacteria (including ... [+] E.coli + Salmonella), Parasites (including Giardia and Cryptosporidium), Microplastics, sand, dirt, and cloudiness

When the company made a foray into the home space, it was with a pitcher , billed as “the only water filter pitcher that removes bacteria and parasites, in addition to microplastics.” It debuted to great fanfare, winning the prestigious International Design Excellence Award (IDEA) GOLD Award as well as a Red Dot design award and Architectural Digest’s Great Design award.

LifeStraw Home is a water pitcher - in glass or BPA-free plastic - that removes bacteria, parasites, ... [+] and microplastics Reduces lead, mercury, and chemicals including PFAS (“forever chemicals”), chlorine, herbicides, pesticides, dirt, sand, and cloudiness.

“We’ve tried to keep a Danish design approach for all our products,” noted Madier. “Minimalistic, sleek, designed for purpose without a lot of gadgety stuff.” Most LifeStraw were designed by Soren Rose, a multi-disciplinary design firm based in Copenhagen (the Sip, however, was designed in-house).

But the company’s most impactful design has nothing to do with a product. It’s their give-back program : the purchase of any one LifeStraw product provides a year of safe water to a child in need. Over 9.6 million children in seven countries (Bangladesh, Mexico, Haiti, Venezuela, Kenya and Ghana) have benefited from this program so far, and over 3,400 schools have received water purifiers as well as on-site education and training. A win-win for all.

8 Best Water Bottles, Tested by Experts

Our top-tested picks are are durable, functional and will help you stay hydrated on the go.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

After testing hundreds of water bottles in the last decade, our analysts have determined which bottles stand out amongst the thousands of models on the market in performance and ease of use. The best water bottles in our tests are lightweight, but durable, easy to clean, reasonably priced and offer versatility in capacity and drinking spouts.

In the latest side-by-side test conducted by the Good Housekeeping Institute 's Kitchen Appliances and Innovation Lab, we rigorously evaluated 37 water bottles with the help of over 40 consumer testers who incorporated them into their daily routines. Utilizing over 1,031 ounces of water in our comprehensive Lab tests for temperature maintenance, spill resistance, and leak prevention, we assessed each bottle's performance. Drawing from both our laboratory evaluations and real-world usage scenarios, coupled with the insights from our seasoned product experts, we gathered our top recommendations for water bottles that excel in temperature retention, durability, cleanability, and other crucial criteria.

Our top picks:

• Best overall water bottle: RYETI Rambler 26 oz. Bottle with Chug Cap
• Best value water bottle : Nalgene Sustain Tritan Water Bottle
• Best water bottle for the gym: Takeya Actives Insulated Water Bottle

You can read more about how we test water bottles in our Lab — plus everything you need to know about shopping for a water bottle — at the end of this guide.

YETI Rambler 26 oz. Bottle with Chug Cap

This 26-ounce Yeti Rambler is highly versatile and perfect for everyday use. It's comfortable to hold, doesn't sweat and is easy to drink out of, thanks to the tapered chug cap.

Like all of Yeti's Ramblers, this water bottle's lid unscrews smoothly and has an oversized handle that makes it easy to hold. We especially love that the mouthpieces are all interchangeable amongst the various Rambler bottles that range in size from 12 ounces to 64 ounces. Our favorite part about this water bottle is that it's dishwasher-safe for easy cleaning. The Rambler's wide mouth also makes it easy to wash by hand — and add ice cubes.

In Lab tests, this water bottle didn't leak and retained temperature rather well. We had a few consumer testers try this bottle, and one said, "I used it while traveling during the holidays. It fit well into the water bottle pocket of my backpack. The handle on the bottle made it easy to grab and carry. It definitely kept my water cold throughout the entire day. It did not fit into any of the cup holders of the car, which was a little annoying during a long drive."

If you prefer a lightweight, plastic water bottle over stainless steel, Yeti just came out with its plastic Yonder line , which comes in five colors, two sizes and is compatible with the chug cap as well.

Take note: Bigger sizes of this water bottle tend be on the heavier side and this bottle won't fit in every car's cupholders.

Nalgene Sustain Tritan Water Bottle

Nalgene water bottles are popular for a reason. With loads of five-star ratings on Amazon, a price tag under $20 and a leak-proof seal , this water bottle is a popular pick with both consumers and GH Institute experts. This 32-ounce wide-mouth bottle is easy to drink from and take along anywhere: It's lightweight with a plastic loop for carrying. Plus, its screw top makes for a tight seal so you can toss it in without fear of leaking.

"Although it's sizable, the bottle is so lightweight which makes bringing it to work or the climbing gym super easy. It takes up space in your bag, but it doesn't weigh you down like a competitor can," one consumer tester noted. They also noted how easy the bottle was to fill with water.

This Nalgene water bottle comes from their Sustain line , which means that the Tritan BPA-free (according to the manufacturer) bottle is made with material derived from 50% plastic waste. We love the measurement markings on the side that allow you to keep track of how much you’re drinking through the day and that this bottle comes in over 30 different colors to match your outfit or favorite color.

Take note: This bottle is dishwasher-safe, and the colors stay bright even after many washes, though the markings wear off over time. It's not recommended if you're looking for a bottle to keep your water cold for long periods of time as there isn't any insulation.

Takeya Actives Insulated Water Bottle

This Takeya bottle is one consumer tester's go-to option for everything from working out to traveling, thanks to its smart details. "I love that there’s a grippy strip around the lid, which makes it easy to open the top if it’s been tightened too much," she said. While in our Lab tests, we found the bottle to be durable, not denting and that the seal was leak-proof.

The spout is easy to flip open and wide enough to sip out of mid-workout. It's insulated and doesn't sweat, and its matte finish makes it easy to grasp. Plus, it has a silicone grip on the bottom, which helps the bottle stay in place in a cup holder or on a table. Its large handle makes it easy to tote around the gym from one piece of equipment to the next. The wide mouth means the bottle is easy to fill with water or ice and easy to clean — it's even dishwasher-safe.

This style of water bottle comes in a range of sizes and lid options like the spout lid — there’s even one for kids . Another great option from Takeya for the gym is the Takeya Sport , which won a GH 2023 Fitness Award .

Take note: This water bottle's temperature retention isn't as good as other insulated models tested and like most straws, this straw requires additional care when cleaning due to the narrow shape.

STANLEY IceFlow Fast Flow Bottle

The Stanley IceFlow Fast Flow Bottle is our best-tested insulated water bottle . While Stanley Cups are having a viral moment on TikTok, we don't want you to miss the water bottle that GH Test Engineer Alec Scherma found to be one of the more unique bottles out there. The drinking spout's design allows for faster drinking and features an easy screw-off cap.

The bottle's handle is extremely sturdy. Though it's close to the spout, it rotates down so it's not in the way while drinking. It also features a hook that holds the bottle's cap. "I thought the design of the lid was super smart where you can hook it onto the handle and it stays on there pretty securely. You can even drink with the lid on the handle!" said one tester. While this bottle is dishwasher-safe, you can also remove the entire mouthpiece to hand wash it.

"I like how light this water bottle is and it still keeps my ice water pretty cold throughout the day," said a tester. "I also love the 'fast flow lid.' I love this kind of water bottle sip."

Looking for a more affordable Stanley option? The Stanley Quick Flip Go Bottle also tested very well in Lab and consumer testing.

Take note: Some testers noted that it would have been nice if the bottle had a non-slip bottom or sleeve because the bottle can be loud if slammed onto a countertop. While this bottle comes in multiple sizes, only the 16 and 20 ounce versions can fit in cup holders.

Hydro Flask Lightweight Trail Series Water Bottle

Hydro Flask's 24-ounce Trail Series is slim, noticeably lightweight and held drinks at their temperature for hours in our Lab test. In fact, after 24 hours the water was still cold and only elevated by 14°F. It also comes in seven different colors and a larger 32-ounce size. This bottle is not only our top pick for a stainless steel water bottle, but it's also a great choice for taking on the go whether you are hiking, camping or traveling.

Its walls are made of thinner stainless steel than competitors and it has a perforated handle, which makes it lighter and easier to carry on long treks. "I like how slim it is and lightweight," says Kitchen Appliances & Innovation Lab Director Nicole Papantoniou . "The handle is also soft which makes it comfortable to hold. It fits easily into the side of my backpack and I’m impressed with how well it keeps water cool for."

If you have a few old Hydro Flask water bottles lying around your house, Hydro Flask just launched a recycling program. Through Hydro Flask Trade-in , you can recycle your old bottles and get credits for new bottles like this 21-ounce Trail Series.

Take note: Hydro Flask recommends that you hand wash all of its water bottles. This model also resulted in some dents in our Lab testing.

W&P Porter Glass Wide Mouth Bottle

If you're looking for a glass bottle, this W&P Porter bottle stands out. Its wide mouth makes it feel comparable to drinking out of a cup, but it has a lid so you can take it on the go. It holds 16 ounces of liquid, small enough to fit into most bags. We've even tested this out with transporting cold brew coffee : There were no spills, and we appreciated that the flavor of coffee didn't linger after washing, which can happen with other water bottle materials.

The silicone wrap feels smooth and soft in the hand and helps prevent condensation from building up. We've also tested W&P's narrow-mouth glass bottle , too, but we recommend the wide-mouth because it is easy to add ice to and is easier to clean by hand.

Take note: The bottom can sometimes form a suction on surfaces that makes it feel like it’s stuck to the table. The silicone material was scratched after removing the label from the bottle.

Klean Kanteen Insulated Classic Water Bottle

B-Corporation company Klean Kanteen recently won a GH Sustainable Innovation Award for using certified 90% post-consumer recycled steel for 95% of their products by the end of 2023.

This insulated water bottle is also lightweight with a stainless steel carrying handle and a sturdy stainless steel base. KleanKanteen also sells an assortment of compatible lids in different materials for this bottle and it comes in a few other capacities.

This bottle's insulated design keeps contents cold for up to 47 hours or hot for up to 14 hours, according to the manufacturer. In our Lab tests this bottle was leakproof and retained temperature well. We also appreciated the small mouth opening which is easy to drink out of.

Take note: This bottle dented on every drop in our Lab testing and while it's dishwasher-safe, the small mouth of the bottle makes it harder to hand wash.

Owala FreeSip Insulated Stainless Steel Water Bottle with Straw

Owala's FreeSip Insulated Stainless Steel Water Bottle comes in a variety of different colorways, whether you prefer this brightly colored water bottle or a neutral version . It also comes in 24-, 32- and 40-ounce capacities. There's even a 16-ounce kids' line. Owala claims that the double-wall insulated water bottle keeps water cold for up to 24 hours, which we proved in our Lab.

What makes this bottle especially versatile is how there are two ways to drink from it: Use the "FreeSip" spout that is designed for sipping upright through the built-in straw, or tilt the water bottle back to drink from the spout opening. We like that the locking push-button lid ensures that the water bottle doesn't leak. Even better, you can remove the mouthpiece for easy cleaning and filling. The strap that keeps the mouthpiece closed also doubles as a handle for carrying.

Take note: While the plastic mouthpiece is dishwasher-safe, it's recommended that you hand wash the rest of the bottle to preserve the vibrant powder coat finish. One consumer tester did note that the handle is narrow and isn't as comfortable to carry as other water bottles.

Other good water bottles

Looking for a value pick with a straw? Try the CamelBak Eddy+ Water Bottle for just over $20. It's made of durable, dishwasher-safe plastic and comes in a variety of colors. The bite valve straw makes it relatively easy to sip from on the go and prevents spills and splashes (though we don't recommend tossing it into a bag, as it's not leak-proof).

What about a slim water bottle? S'well Stainless Steel Water Bottle will fit into most backpacks, side pockets and car cup holders, while also being triple-layered insulated. We can confirm that it retains temperature very well. Keep in mind that it dented in Lab testing and you will have to invest in a good bottle brush since it is not dishwasher-safe and has a rather narrow mouth.

In search of a water bottle that doubles as a coffee thermos? The Zojirushi Vacuum Insulated Mug is a 20-ounce stainless steel water bottle that offers the ease of a drinking spout and a lid that covers and protects it. This bottle excels at keeping both hot beverages hot and cold beverages cold. However, we do prefer it as a thermos over a water bottle and appreciate its small drinking spout for sipping hot beverages.

Need a water bottle that also filters your water? Brita Hard-Sided Filtering Water Bottle is a 26-ounce bottle that filters out chlorine, which can affect the odor and taste of your water. Brita does say that its water bottle filter (located in the straw) should be replaced after 40 gallons or approximately every two months for best-tasting water.

Or one with a comfortable handle? LARQ Swig Top Insulated Stainless Steel Water Bottle is lightweight and durable with a built-in soft-touch, wide-grip handle. While it's compatible with three different mouthpieces, we especially like the swig top for ease of drinking. The lid is leak-proof, but it doesn't open with a button — just manually — so it might be harder to open for some.

Aren't drinking enough water daily? Try the HydroJug Half Gallon Water Bottle which holds a half gallon of water to help you reach your hydration goals. However, keep in mind that it won't fit in cup holders or your backpack due to its size.

Also check out this top rated Amazon pick: IRON °FLASK Sports Water Bottle is a popular pick among Amazon reviewers for good reason as it didn't leak in Lab testing and comes with three different mouthpieces and numerous colors. We did find its temperature retention to be not as good as competitors and it did dent during drop testing.

How we test water bottles

In the Good Housekeeping Institute Kitchen Appliances and Innovation Lab, we evaluate each water bottle we test for ease of use, performance and durability. We've tested hundreds of water bottles over the last decade, and in our latest round, we tested 37 water bottles side-by-side to evaluate performance and ease of use.

When we evaluate performance, we test how well they retain temperature and whether they are leak-proof. Pictured here is our drop-tester machine with dyed water that leaked out of a poorly performing water bottle. To test whether a bottle will leak, we fill each water bottle with the same amount of water and food dye. We knock over each water bottle and let it sit on its side for 30 minutes, then check to see if any water seeps through. We also shake each water bottle at full capacity to see if any water escapes.

We evaluate each water bottle to see how well they can retain temperatures. We fill every bottle to maximum capacity with water and then remove a specific amount of water from each bottle, replacing it with a calculated amount of ice. Then the internal water temperature of each bottle is documented multiple times over 24 hours to determine which bottles retain temperature best.

To test durability, we use our drop tester machine. We drop water bottles three times each from a height of 5 feet and note any damage that occurs.

To evaluate ease of use, we consider how each bottle opens and closes. Using either a dishwasher or dish soap and a brush, we test how easy it is to clean each water bottle.

In addition to Lab tests, we send water bottles to consumer testers to get their opinions on how water bottles fare in real life.

What to look for when buying the best water bottle

✔️ Material: There are three main materials used to make reusable water bottles: plastic, glass and stainless steel. Plastic water bottles are usually lightweight and durable, but they can sometimes absorb the flavor of tea or coffee. If cleaned properly, glass water bottles won’t impart any flavor into your water, but they can be delicate or heavy. Stainless steel is a lightweight alternative and is often used for insulated bottles that are great for keeping hot beverages hot and cold beverages cold; they're often not dishwasher-safe.

✔️ Size: Water bottles can be as small as 12 ounces, which is perfect for a child or for fitting into a small bag. They can also be as large as a gallon, which is convenient for a picnic with friends or long car rides. A common everyday size for a water bottle is around 24 to 36 ounces — small enough to fit in a backpack, but large enough that you don’t need to refill often. The larger the water bottle, the wider it likely is, which is something to keep in mind when it comes to cup holders.

✔️ Drinking spout: There is a drinking spout for everyone, and some brands even offer multiple drinking spouts to appeal to different customers.

• There are insulated water bottles with wide mouths which are great for big gulps of water but are more prone to spilling if you're not careful.
• Small mouths like sipping spouts might offer less water flow, but there is less chance of spilling and they're often good for hot beverages.
• Chug caps or larger spouts are great if you prefer to drink quickly without making a mess.
• A bottle with a straw is helpful when you’re on the go or working out.
• There are even newer hybrid drinking spouts like with the Owala FreeSip where you can sip upright through the built-in straw, or tilt the water bottle back to drink from the spout opening.

✔️ Additional features: Some bottles feature handles for carrying around, non-slip sleeves so bottles stay put on countertops or remain in your hands even when sweaty and an additional larger bottle opening for easier cleaning or filling bottles with ice.

Water bottle care and maintenance

All water bottles should be cleaned regularly to eliminate bacteria and prevent mold growth. If a water bottle must be hand-washed, look for one with a wide mouth and fewer parts, and use a bottle brush to thoroughly clean the interior with soap and warm water. If a bottle has a straw, we recommend that you hand-wash it for a thorough clean, even if the bottle states that it is dishwasher-safe.

If you're not a fan of using a bottle brush to clean a water bottle, ensure that it’s dishwasher-safe before purchasing. The dishwasher's tough environment can deform the seal on bottles that aren't dishwasher-safe and ruin the exterior over time, so always check if a bottle is dishwasher-safe.

Which brand of water bottle is best?

We rely on hundreds of data points across several different tests to determine the best water bottle brands on the market. When it comes to most water bottle brands, we've also tested multiple models within their water bottle lines.

While we only feature water bottles that performed well, our top performers are from Yeti , Stanley , Hydro Flask and Takeya . These water bottles outperformed others, offering great ease of use, durability, temperature retention and leak-proof lids. They were also popular among our consumer testers.
