A useful gear roundup with the mission of finding the best water filter bottle for travel, hiking and backpacking.
Clean drinking water is our most precious resource. It’s something that we often take for granted when we freely pour purified water directly from our home country’s faucets. But, it’s not until we travel abroad or head out for a backcountry hiking trip that we realize just how important it is to have a sustainable and safe water filtration bottle.
It took me a while to realize this.
After the first year of full-time travel, I really was desperate for an easy and sustainable water purification solution. I couldn’t justify adding any more single-use disposable plastic bottles to landfill or popping any more foul-tasting water purification tablets.

Luckily, this is about the same time that new filtration technology and innovative, travel-inspired water purification bottles with built-in filters started emerging in hostel common rooms and trekking lodges.
Initially convinced that this was some kind of magic, I was shocked. These bottle purifiers could turn dirty and unsafe water into safe, and great-tasting clean water– devoid of heavy metals and harmful parasites!
And, so my search for the best water filter bottle for travel began.
Fast-forward four years later and I'm still living full-time on the road. I've tried just about every travel water filter on the market, from ultralight gravity filter systems to membrane ultrafiltration straws. After a lot of trial and error, I'm convinced that the best solution for travelers is to buy a reusable water filtration bottle.
That's why, in this gear guide, I'll summarize the best filtered water bottles to help you travel and hike freely, without worrying about the environmental and health impacts of drinking water.
Quick Answer: Here Are the Best Travel Water Bottle Filters
I get it, who wants to read an entire essay about the best water purifier bottles?
That's why I'm giving you the quick answers right here, with links to buy the bottles from Amazon, REI, or directly from the manufacturer.
The absolute best travel water filter bottle is the Grayl GeoPress
An all-in-one travel water bottle filter and water purifyer using an innovative and ridiculously easy-to-use press system. Turns any dirty or suspicious water into clean, great-tasting drinking water so we can focus on the adventure. This is the only water bottle filter that allows us to actually transport clean water, but more on this below.
I've personally used this bottle for a few years on a daily basis. I've used it to filter tap water in India and questionable water sources in Colombia. I even use it to press out any chemical or metal tastes from safe tap water in countries like Australia and the United States.
But, you didn't come here just to hear about one filter bottle. So, here are 9 more travel water filter bottles to consider:
- Grayl UltraPress - the newer, lighter Grayl. Great for hiking or when you need an ultralight purifier bottle.
- Epic Nalgene Ultimate Travel OG - good straw-style water bottle filter for lovers of Nalgene
- Lifestraw Go - convenient for everyday use
- Surivimate - budget straw filter bottle
- LARQ Purevis- insulated UV-C light filtration bottle
- Nalgene Bottle with Steripen Ultra - unique solution combining a versatile UV filter with a regular Nalgene
- Seychelle Advanced - unique bottle filter removes radioactive contaminants
- Katadyn BeFree - very lightweight and compactable filter bottle
- CrazyCap Pro - popular UV filter lid compatible with a wide range of plastic bottles
Below I'll give a thorough rundown of each bottle, outlining the pros, cons, and ranking important features to help you make an informed decision to purchase the best water filter bottle for your travels and adventures.
But First, Why Should Travelers Invest in the Best Water Filter Bottle In the First Place?
Still not convinced that a water bottle-style filter is the best option for travel? Let me help with that.
Alternatively, skip directly to the review of each bottle below.
1. A Filter Will Keep you Safe from Harmful Bacteria & Parasites
Access to safe drinking water anywhere is likely already your biggest motivation for buying a filter bottle.
However, did you know that most of the bottles in this roundup remove 99.99% of harmful contaminants, even from dirty, stagnant water sources including lake water and even muddy puddles?
Most importantly, the best water bottle filter should filter bacteria such E. coli, which is the cause of Traveler's Diarrhea, more commonly known as Delhi belly, Bali belly, Montezuma's revenge, or the Aztec two-step. Whatever you want to call it, the Rangoon runs is serious business– and the leading cause of illness in travelers overseas.
2. Using a Filter Bottle While Traveling Reduces Plastic Waste
Secondly, the impact of one traveler simply swapping to a reusable water bottle rather than buying two 1.25L plastic water bottles each day is remarkable. Consider a 3-month backpacking trip in South East Asia. That's over 180 plastic bottles either ending up in landfill or more likely, burnt up into our atmosphere.
3. Even an Expensive Travel Filter Bottle Will Save You Money
Yes, a high-quality water bottle filter might seem like a considerable investment for just a bottle.
But, consider the cost of the above example. Those plastic bottles might seem cheap, but the cost adds up. When we total the cost of the single-use bottles with the inevitable use of water purification tablets on hikes, the yearly cost is in the several hundreds of dollars.
A good, reliable travel filter bottle will save you money!
4. Bottle Filters are By Far the Most Convenient and Easy-to-Use
Yes, but why not just buy a gravity filter system, simple straw filter, or squeeze filtration system for travel?
Because chances are that you simply will give up on these systems because they are too inconvenient.
A travel-ready filter bottle is simple, easy to use, clean, and doesn't feel like a chore.

Detailed Breakdown: The 10 Best Water Bottle Filters for Travel & The Outdoors
So, here it is, the long breakdown of the best water bottle filters for travel and hiking.
I've rated each of these bottles based on:
- Ease of use - convenience for everyday use
- Quality of clean water - taste and range of protection
- Flow rate - how quickly the bottle turns bad water into safe water (measured in liters per minute)
- Durability & material - what the product is made from, and how long it will hold up
- Filter lifespan & cost of replacement - filter lifespan in gallons & liters, and how much a replacement costs
For a further breakdown of these criteria, skip to the bottom of this article.
Otherwise, let's get into the review!
1. The Best Bottle Filter For Travel: The Grayl GeoPress
- Ease of use: 5/5 - Very Easy
- Quality of clean water: 5/5 - Excellent Protection & Taste
- Flow rate: 5 liters/minute (8 seconds per 24oz)
- Durability & material: 5/5 - BPA-FREE polypropylene #5, food-grade silicone, TPE, and ABS food-grade plastic to withstand drops of 10ft+ onto concrete (full of water)
- Filter lifespan & cost of replacement: 250 liters | $29.95
You already know that the Grayl GeoPress is the world's best water bottle filter for travel, hiking, and everyday use. It's the only bottle on the market that can purify dirty water and store it inside the same system with a best-in-class outstanding flow rate.
The GeoPress works by filling dirty water into the outer "case", and pressing the inner filter bottle into it, effectively creating fresh, clean drinking water from any water source, without any risk of cross-contamination.
This makes the GeoPress extremely versatile. It allows travelers to filter 24 oz of water in just 8 seconds, which is great for cooking in the backcountry and sharing water with others by letting them fill their own bottles with the purified water.
The quality of water and range of protection is also best in its class, effectively removing:
- 99.99% of viruses
- 99.9999% of bacteria
- 99.9% of protozoa
- All particulates including microplastics, sediment, and silt
- Chemicals including chlorine, benzene, chloroform
- Heavy metals including lead, arsenic, chromium
This level of filtration effectively makes the Grayl system also a water purifying bottle, since it is able to filter out bacteria, protozoan cysts, and heavy metals– plus waterborne virus as well. Protection from virus is paramount for any traveler making their way to continents like Asia, Africa, and Central/South America, where a purifier bottle is essential.
The Grayl states that the cartridge lasts roughly 350 presses. However, by filtering mostly clean water without particulates, I've managed to get away with using at least double this amount. Filter cartridges are also very easy to find around the world in outdoor stores, and Grayl even has a recycling program for these.
I've used this bottle for several years and have very few gripes with it. The weight and size are the only downsides I can think of for weight-critical hikers. However, if this is a priority, the issue is solved by opting for the UltraPress option instead.
2. The best LIghtweight Water Bottle Filter: Grayl UltraPress
- Ease of use: 5/5 - Very Easy
- Quality of clean water: 5/5 - Excellent Protection & Taste
- Flow rate: 3 liters/minute (10 seconds per 16.9oz)
- Durability & material: 5/5 - BPA-FREE polypropylene #5, food-grade silicone, TPE, and ABS food-grade plastic to withstand drops of 10ft+ onto concrete (full of water)
- Filter lifespan & cost of replacement: 150 liters | $24.95
The runner-up place for the world's best water bottle filter for travel is the Grayl UltraPress. This is a new addition from The Grayl, coming in a 16.9 oz (500 mL) bottle as opposed to the 24 oz (710 mL) GeoPress. The smaller size bottle means that is much lighter, at only 12.5 oz (354 grams), and fits much better in a backpack drink bottle holder.
Additionally, the UltraPress provides the same safe water protection (removing viruses, bacteria, protozoa, heavy metals) as the original GeoPress. Due to the lighter weight and better packability, I've decided to swap out my original GeoPress and use the UltraPress instead for everyday use and travel.
For longer hikes where I need more water, I use it to filter and fill my 3L water bladder in my camera backpack.
Bottom line: If weight and packability are a priority when choosing the best travel water bottle filter, pick the UltraPress. Alternatively, if you prefer a larger capacity and longer filter duration, go for the GeoPress.
3. Epic Nalgene Ultimate Travel OG
- Ease of use: 4/5 - Easy
- Quality of clean water: 5/5 - Excellent Protection & Taste
- Flow rate: information not available - reported more restricted flow than Lifestraw Go
- Durability & material: 5/5 - BPA BPS free Tritan plastic
- Filter lifespan & cost of replacement: 380 liters | $30
The next best filter water bottle after the Grayl systems is made by Epic Water Filters in collaboration with Nalgene.
The Epic Nalgene OG Ultimate is a straw-style filter inserted into a durable wide-mouth Nalgene Tritan bottle. This makes it a lightweight and very durable water bottle filter that is an excellent choice for hiking and outdoor use.
The filtration system creates potable water from dirty water using its "Outdoor Adventure Filter", which gets rid of:
- 99.95% of viruses
- 99.9999% of bacteria
- All particulates including microplastics, sediment, and silt
- Most chemicals including chlorine (96.8%), fluoride (68%), nitrate (88.2%), and sulfate (91.8%)
- Heavy metals including lead, arsenic, copper, etc (88.4%-99.5% depending on the metal)
For a full list check out the performance data tests.
While the filter quality isn't quite as good as the one from Grayl, they do last for nearly twice as long as the UltraPress (I still think that Grayl is being too conservative). Additionally, the water quality is extremely good and tastes great, even when drinking from dirty water sources.
A potential downside to this system is that finding replacement filters can be tricky, especially while traveling abroad. Also, after using straw filters for a while, I've quickly come to dislike them since they are effectively useless for filtering water for cooking or sharing.
4. Lifestraw GO Bottle Filter
- Ease of use: 4/5 - Easy
- Quality of clean water: 4/5 - Great Protection & Taste
- Flow rate: 1.2 liters/minute
- Durability & material: 3/5 - BPA-FREE food-grade plastic
- Filter lifespan & cost of replacement: 4000 liters | $24.95
LifeStraw (Vestergaard) is a company that's been around since 2005 and is credited for inventing the filter straw during its work to eradicate the Guinea worm in developing nations.
The LifeStraw Go bottle is one of the most popular water filter bottles for travel as it's lightweight, affordable, and filters up to 4,000 liters before needing a replacement filter.
The LifeStraw works by inserting its patented straw filter inside the bottle, which when sucked, forces water through hollow fibers of 0.2 microns in size, meaning bacteria & parasites cannot pass, and only clean water gets through.
The microfilter effectively removes:
- 99.999999% of bacteria
- 99.999% of parasites/amoebas/cysts
- 99.999% of microplastics
In my experience, LifeStraw products have always kept me safe, but the resulting taste of the water is nowhere near as clean as what you will get with press filters like the Grayl. Again, these systems do not create clean water for storage, forcing travelers to carry dirty water, and only filtering it just before it hits the mouth.
However, if an affordable, long-lasting filter bottle that will likely do the job of filtering water for immediate drinking is what you're looking for, then this is a great option. Just keep in mind that the LifeStraw is not a purifying bottle and will not remove any waterborne viruses.
5. SurviMate Bottle Filter
- Ease of use: 4/5 - Easy
- Quality of clean water: 3/5 - Decent Protection & Taste
- Flow rate: 0.55 liters/minute
- Durability & material: 3/5 - BPA-free, food-grade Tritan Copolyester
- Filter lifespan & cost of replacement: 1500 liters | $18.99
I've included the next outdoor and travel water bottle filter in this roundup because it is currently one of the most popular filter bottles on Amazon, with thousands of 5-star reviews.
I'm going to be honest, I've never used this filter. So, all I can do is provide you with the specifications and a summary of reviews.
At first glance, the SurviMate Filtered Bottle seems like a cheaper copy of the better-tested LifeStraw Go Bottle. This bottle claims to use medical-grade PP cotton, antibacterial beads, medical-grade hollow fiber UF membranes, and a coconut shell-activated carbon filter to remove 99.99% of E. Coli, with not much more information available regarding heavy metals, viruses, or parasites (we can assume it does not filter these).
Again, the reviews of this filter are phenomenal, which must account for something. However, I am skeptical about its public reports, which come from independent Chinese labs (even then, from a questionable source). Furthermore, while I haven't seen a single review claiming that the filter resulted in illness, Amazon users have commented that the initial plastic odor and taste are quite bad.
In conclusion, this is a cheap water bottle filter that it seems tens of thousands of people are happy with. I personally would invest in a more reputable brand. But, if the price is the absolute top priority for you, it might be worth digging into.
6. LARQ PureVis
- Ease of use: 5/5 - Very Easy
- Quality of clean water: 3/5 - Decent Protection & Taste
- Flow rate: 1.5 liters/minute - 20 seconds for 17oz bottle
- Durability & material: 4/5 - polished stainless steel
- Filter lifespan & cost of replacement: N/A - replacement cap $69.95
LARQ became famous when it made headlines for asking the highest valuation in history on the popular TV show 'Shark Tank'. Today, LARQ produces one of the world's top UV-C bottles, the LARQ PureVis.
This unique UV-C light works by damaging 99% of bacteria, viruses, and mold inside the bottle, effectively making it "self-cleaning" and "purifying". It takes roughly 20 seconds to purify the water inside the 17 oz bottle, by bouncing the UV-C light around inside from its rechargeable lid.
This is an innovative water filtering solution that makes it one of the simplest and easy-to-use water bottle filters for travel. However, after testing out a LARQ bottle from a questionable water source (even filtering the water for 3-minutes on the adventure mode), I realized that while the water might be safe to drink, it tastes awful.
The reason is that this filter does not remove particulates, heavy metals, or silt that you will be sure to find in tap water across the developing world. As a result, the LARQ UV-C is a great filter for everyday use when filtering already clean drinking water, but I would not recommend it for outdoor use or as a travel bottle in countries with poor water quality.
7. Nalgene Bottle With Steripen Ultra
- Ease of use: 2/5 - A bit annoying
- Quality of clean water: 3/5 - Decent Protection & Taste
- Flow rate: 0.75 liters/minute
- Durability & material: 5/5 - BPA-free, food-grade Tritan Copolyester |
- Filter lifespan & cost of replacement: 50 liters per charge (8000L lifespan) | $269.95
The SteriPen is a popular UV-C light filter that is gaining popularity with the outdoor crowd. While quite expensive, the pen is tiny, and claims to filter up to 50 liters of water on a single charge!
Combining the SteriPen with the (so far) indestructible Nalgene 1.0L wide brim bottle is a popular option when filtering clean stream water in the outdoors. That's because this DIY water filtration solution is the lightest system on the list and does a good job of removing nearly all bacteria, viruses, and common pesky parasites like giardia (however, it won't remove the parasite's eggs, including tapeworms).
Again, as with all UV-C filters, you will have the issue of particulates and silt. It also involves a few extra steps, so this isn't the most convenient for everyday use. With that said, this system is more tailored toward hikers looking for that peace of mind when drinking fresh stream water and serves this purpose well.
8. Seychelle Advanced
- Ease of use: 4/5 - Easy
- Quality of clean water: 4/5 - Great Protection & Taste
- Flow rate: unknown - more resistance than LifeStraw Go
- Durability & material: 4/5 - EPA approved low-density #4 plastic
- Filter lifespan & cost of replacement: 378 liters | $28.95
Next up is another very popular water bottle filter, especially with the survival and prepper crowd.
The Seychelle Advanced Flip Top Bottle is an American-made filter system with very reputable filter testing reports. Similar to the LifeStraw Go, the Seychelle water bottle filters use a straw filter to purify water on demand. What makes the Advanced filter stand out is its ability to filter radiological contaminants– yep, you head that right!
Additionally, this system clears out 99.99% of
- Odors
- Cloudiness and silt
- Chlorine and other toxic chemicals
- Heavy metals
- Bacteria
- Viruses
- Parasites
Furthermore, this bottle is very affordable and can be used with a convenient pump to filter larger amounts of water for storage, sharing, and outdoor cooking. The biggest gripe that I have with this system is that it is almost impossible to find a replacement filter when traveling. If this wasn't the case, I'd strongly consider it the number-one best water filter bottle for travel.
9. Katadyn BeFree 1.0L Squeeze Bottle Filter
- Ease of use: 5/5 - Very Easy
- Quality of clean water: 4/5 - Great Protection & Taste
- Flow rate: 2 liters/minute
- Durability & material: 3/5 - Hydrapak SoftFlaskTM made of TPU, 100% PVC, and BPA free
- Filter lifespan & cost of replacement: 1000 liters | $49.95 (replace entire bottle)
The BeFree by Katadyn is one of the most popular water bottle filters for backpacking and long-distance hiking. This largely comes down to its ease of use, packability, and ultra-lightweight design. At just 2.3 ounces, this empty flask and filter system rolls up into your backpack or pocket!
This system filters up to 2 liters per minute by squeezing a collapsable flask full of dirty water through the filter mouthpiece. This filter is very small but works extremely well considering the 0.1-micron hollow fiber microfilter eliminates protozoa (99.99%) and bacteria (99.9999%) from 1,000 liters of water before needing a replacement.
Additionally, the ability to "squeeze" water through the filter means that hikers and backpackers can fill up their water reservoirs, a much better solution than an on-demand filter straw. However, just like the LifeStraw and other stray-style filters, you will be carrying dirty water until you squeeze it into your mouth or another bottle.
While I would recommend this as the number one water bottle filter for ultralight hikers and backpackers, having a collapsable bottle for everyday use when traveling isn't very practical. Furthermore, the Katadyn BeFree does not filter out viruses, which means your water will not get 100% safe water from this filter in the majority of countries outside North America, Europe, and Oceana.
10. CrazyCap Pro
- Ease of use: 5/5 - Very Easy
- Quality of clean water: 3/5 - Decent Protection & Taste
- Flow rate: 0.5 liters/minute - 60 seconds for 17 oz
- Durability & material: 4/5 - Triple-vacuum insulated stainless steel
- Filter lifespan & cost of replacement: N/A | N/A
The final water bottle filter on this list is another UV-C bottle offering similar performance to the LARQ PureVis bottle at a cheaper price point. Again, the CrazyCap Pro bottle comes with all the drawbacks and caveats you'll get with any UV light filter bottle. But, it could be a better pick for those who don't need to filter extremely dirty water.
The bottle is also very well-designed and provides triple stainless steel insulation to keep your water cold for up to 12 hours. A unique feature of the CrazyCap is that in addition to the standard bottle, the cap is designed to fit on most cola-sized plastic bottles.
What Makes a Great Reusable Travel Water Filter
As promised, here's a quick breakdown of what you should consider when choosing the best water filter bottle for travel, outdoor, or everyday use.
1. Ease of Use
When it comes down to it, the reason why the world uses over 1 million single-use plastic bottles every single minute is convenience. When choosing a water filter bottle, you'll want to ask yourself a few questions.
- How will I use it? Day to day, for special trips, or for backcountry use?
- How likely am I to commit to filtering my water through this bottle?
- Where am I planning to use the bottle?
A water filtration bottle offers the most convenient way to filter pure water since it doesn't require a complex setup to do so.
2. Quality of Clean Filtered Water (Taste & range of Protection)
Of course, the quality of clean, filtered water should be a top priority. Consider purchasing a bottle based on its produced water taste, and odor. Many bottles will filter out gross chemicals like chlorine dioxide and heavy metals, which is great for filtering water already deemed "safe".
While taste is important, quality should also be considered based on your range of protection. Typically, press filter systems like the Grayl will deliver better safe water than quick-sip straw systems since they will filter out viruses as well as bacteria and protozoa cysts.
At a minimum, travelers will want adequate protection from:
Bacteria & Protozoa
Bacteria is a broad term that describes unicellular microorganisms. When filtering questionable water sources for drinking, the bacteria that we are concerned about are those that cause disease and other issues. The main examples of harmful bacteria commonly found in water include:
- Escherichia Coli (E.Coli) - causes travelers diarrhea when consumed
- Campylobacter Jejuni - Causes infections with symptoms of cramping, diarrhea, fever and pain
- Hepatitis A - yes, this is a bacteria that causes severe issues like jaundice, fever, chronic fatigue up to 28 days after exposure
- Salmonella - not just from eating raw chicken. Salmonella is a common pathogen which will cause you severe feveres, headaches, diarrhea, and pain
- Cryptosporidium - a protozoan acting in a very similar way to parasites. This causes severe and very painful diarrhea and commonly occurs in even very clean-looking drinking water.
Luckily, nearly all water filter bottle systems in this roundup will protect travelers from the majority of bacteria and protozoa.
Parasites
If you've ever been infected with a common parasite like Giardia, you'll know that his is one of the worst experiences your bowels could ever endure. Luckily, parasites are usually larger than bacteria, and a filter with a very small micron filter will usually remove these.
Viruses
Viruses are one of the most difficult things to filter out of water. Water bottles that are capable of removing harmful global waterborne viruses are called water purifiers.
This aspect is where the Grayl is the best water filter bottle for travelers visiting one of the around 100 countries in the world where this can be a problem. In my opinion, bottles like the LifeStraw Go or the Katadyn BeFree are only useful in countries without this risk.
3. Filter Flow Rate or Time to Clean Water
Another reason why some people stop using their water filter is that it just takes too long to filter water. This specification is called flow rate, measured in liters per minute.
A reusable water bottle doesn't require the filtration of gallons of water at a time, but slow flow rates can get annoying.
This is where on-demand straw-style filters like the LifeStraw are convenient since there is little to no waiting time. However, these straws do take some time and effort to suck the water through and don't provide a lot of water at a time.
UV-C light filters like the LARQ are designed to break down and kill bacteria and viruses inside the bottle, and generally take the most time, but the least effort to do so, since everything happens inside the bottle at the press of a button.
On the other hand, press and squeeze systems like the bottles from Grayl and Katadyn, require slightly more initial effort to get clean water. However, provide the ability to prepare large quantities of safe water at a time.
4. Filter Bottle Material & Durability
Travelers know that investing in products with poor durability is not a good idea. This is due to the simple fact that things get banged up on the move. Whether you're chucking your filter bottle in a backpack, dropping it off a hostel bunk, or throwing it in the back seat of your van, chances are it'll suffer some scuffs and bruises along the way.
When grading a water filter bottle for its durability, it's best to consider the material of both the bottle and filter. Hard, durable plastics on bottles like Nalgene and Grayl's are much more durable than soft plastics and even stainless steel. Soft plastics have a tendency to warp, while stainless bottles often are left with dings and cracks.
5. Filter Longevity & Ease/Cost of Replacement Filters
Even the best water filter bottle will need a replacement filter after a while. Initially, people tend to pay the most attention to the volume lifecycles. While this is important in gauging how much water you can expect to filter between replacements, what I believe is more important for travelers is the ease and cost of the replacement.
For example, in this roundup, you'll find several filters which claim to purify thousands of liters of water. However, it's a good idea to consider where or how you will attain a replacement, especially if you are planning to travel for an extended period.
