Best Filtered Water Bottle Reviews
1. GRAYL Ultralight Water Purifier and Filter BottleView Price
This is our top pick for a filtered water bottle, and it’s perfect for globetrotting, emergency preparedness, outdoor exploring, camping, backpacking, fishing and more. This bottle is ridiculously easy to use – you simply fill it up, press and drink. There’s no waiting, no squeezing or pumping involved, and it can guarantee pure, great-tasting water no matter where you are.
The Ultralight’s award-winning, one-press design means you get purified, clean, great-tasting water in only 15 seconds. And it’s effective: this bottle removes 99.9999 percent of all viruses, including SARS, rotavirus and Hepatitis A, plus 99.9999 percent of bacteria like salmonella and E. coli. This bottle also removes 99.9999 percent of protozoan cysts, including cryptosporidium and giardia. In other words, all the hidden dangers you’d worry about when drinking water from a natural, untreated source, can be addressed by using this bottle.
In addition, this filter can remove sediment and other particulates, chemicals like benzene and chlorine and heavy metals like arsenic and lead. It also addresses taste and odor concerns, making sure the water you drink is clear, clean and great-tasting.
This is a popular, trusted and well-loved filtered water bottle – reviewers report that the Ultralight is easy to use, handy and effective. Many people report successful travels in areas without reliable potable water without any sickness at all since they drank out of their Ultralight for the entire trip. However, some users have reported that the bottle is somewhat difficult to use – and that the pressing becomes more and more difficult as more water is filtered.
2. The LARQ BottleView Price
Billed as the world’s first self-cleaning water bottle and purification system, the LARQ bottle uses UV-C LED light to remove nearly 100 percent of all biological contaminants from your drinking water – all at the touch of a button. In addition, the bottle turns on by itself every two hours in order to clean both the water inside as well as the inner surface of the bottle itself.
Each bottle comes with a rechargeable lithium polymer battery, a USB charging cable and a quick-start guide. Its UV-C light is able to rid all biocontaminants by destroying their DNA. In addition, this bottle keeps your water cold for up to 24 hours. And because it doesn’t use a physical filter, you don’t have to worry about replacing it from time to time to ensure optimal performance.
The LARQ’s UV-C LED chips are small, energy-efficient, mercury-free, non-toxic and economical – its 280-nanometer spectrum is tailored specifically to eradicate bacteria and other contaminants without giving them an opportunity to spread.
Each LARQ bottle features a one-year, limited warranty, which covers replacement or repair of any defective components. Relatively new in the market, the LARQ bottle was named one of TIME Magazine’s 10 Smartest Sustainable Products of 2018.
Reviewers say that the bottle is revolutionary and near-perfection – it looks beautiful and works beautifully, providing great-tasting, clean and crisp water. Some users wish the bottle came in a larger size and that it fit in car cup holders a little more snugly, but overall reviews are overwhelmingly positive.
3. Epic Nalgene OG Water Filtration BottleView Price
Epic is so sure you’ll love this bottle that each one comes with a 100-percent, money-back guarantee, so you can send your bottle back for a full refund if it doesn’t meet performance expectations.
The Nalgene OG filter technology employs both depth and adsorption filtration to reach contaminant removal down to one micron. Activated coconut carbon fiber mesh surfaces adsorb contaminants ranging from heavy metals and pharmaceutical residuals to cysts, herbicides and other chemicals. The bottle’s depth filtration features layers of coconut carbon fiber that remove suspended contaminants as your water moves through millions of layers of filtration media.
This type of filter media is particularly environmentally friendly, and everything associated with this bottle is BPA- and BPS-free. The bottle is extremely durable and dishwasher-safe, and all materials are 100 percent food-grade as approved by the FDA, along with being completely recyclable, gluten-free and vegan.
Reviewers are especially impressed by how great the filtered water tastes – especially those who bring their filtered bottle on trips to areas where water quality is questionable. Nalgene has a solid following of longtime fans, many of whom are happy to see one of their favorite water bottle brands with a filtered option. Some users express disappointment that the bottle did not work as well as expected on natural sources like rivers and streams, and they suggest that this bottle is best suited for filtering already-treated tap water.
4. Brita Premium Filtered Water BottleView Price
Brita may be the best-known name in water filtration and purification. This 26-ounce bottle allows you to enjoy Brita-level filtered water while you’re on the go. The bottle features durable, hard-sided, BPA-free plastic and a one-handed push-button lid, plus a straw.
With a relatively small, but hardworking, activated carbon filter, the Brita bottle can replace up to 300 conventional, single-use plastic water bottles, allowing you to both save money and reduce landfill waste.
In addition, the bottle is easy to clean and maintain; it’s top-rack dishwasher safe, and its filter should be replaced after every 40 gallons treated – or approximately every two months. Because its level of filtration is rather simple, this water bottle is best used with pretreated municipal water; you won’t be able to depend on it to filter out more dangerous pathogens. But with a reasonable price, this one’s certainly a good, budget-friendly investment to make in ensuring you have filtered water while you’re at class, at the gym, or going for a run or bike ride in the city.
Reviewers appreciate the easy-to-sip straw, the large capacity of the bottle and the fact that it’s dishwasher safe. It’s reportedly easy to carry around and fits well in most standard cupholders – and if you don’t like the chlorine taste of many municipal water supplies, reviewers say this bottle works like a charm to remedy taste and odor issues. However, some users have reported bottle leaks, and the material used isn’t the most durable, so you might want to leave this one at home during some of your more rugged and challenging hikes or adventures.
5. SurviMate Filtered Water BottleView Price
The SurviMate filtered water bottle features four advanced, high-performance filters, including medical-grade, hollow-fiber UF membrane, coconut-shell activated carbon, beads and medical-grade PP cotton. The result is that this bottle protects you and your family from heavy metals and harmful chemicals, along with biological contaminants.
All SurviMate bottles are manufactured from food-grade tritan copolyester, which is both BPA-free and FDA-approved, along with being durable and heat-resistant. The filters should be replaced roughly every 1500 liters filtered, which may last as long as one year.
And if you’re a major adventurer, you can count on your SurviMate bottle not only to keep you hydrated in even the harshest outdoor conditions, but also to guide your way through the built-in compass featured in the water bottle’s top.
These bottles require no batteries or bulbs, no chemicals and no pumps or squeezing – you simply sip around five to eight times to access clean, fully filtered, safe water.
This bottle gets high marks for its classy look, good selection of colors, ease of use and environmentally responsible materials. Reviewers also report that the filtered water tastes great, and the built-in compass comes in handy on hiking and camping trips. Some users report that the bottle can feel a little heavy when full, while others are quick to praise the company’s fast and helpful customer service. In addition, many users point out that the filters are extremely easy and user-friendly to change.
6. LifeStraw Go Filtered Water BottleView Price
This bottle can remove nearly 100 percent of bacteria, parasites and micro-plastics using an activated carbon capsule that works in two stages. In addition, water from this bottle will taste great – chlorine and organic chemicals like volatile organic compounds, pesticides and herbicides are also eradicated. And one of its best qualities is its convenience – with this water bottle, your water is actually being filtered as you drink it.
Just make sure to note that the Lifestraw filtered water bottle does not remove or kill viruses.
LifeStraw is an extremely well-known and trusted filtered water bottle provider. All LifeStraw bottles undergo rigorous testing – their .2-micron filter size also addresses turbidity. And all of their performance claims are verified by outside parties including the U.S. Environmental Protection Agency. It’s BPA-free and features a food-grade silicone mouthpiece.
Because it’s designed for travelers/adventurers, you can use this filtered water bottle to effectively purify water from streams and lakes as you travel, hike, etc. And with proper use and maintenance, your bottle will filter up to 1000 gallons of water. You can also feel good about your purchase in the sense that for every Lifestraw bottle purchased, a school child in need will receive clean water for an entire school year.
Reviewers love the LifeStraw’s effectiveness and reliability, though some noted the limitation of the water for drinking purposes only. Since the filter mechanism is part of the drinking straw, you can’t use the LifeStraw to purify water for cooking. Others have reported that water can be difficult to drink through the straw; it takes a lot of suction to both start and keep the water flowing up through the straw.
7. Joypur Portable Filtered Water BottleView Price
This filtered water bottle offers a world-class filtration system that features a medical-grade hollow-fiber UF membrane, along with coconut shell activated carbon. Its three distinct stages of filtration allow it to filter out impurities while also protecting taste and odor.
Featuring an advanced design, the 22-ounce water bottle is both leakproof and durable, and it features a food-grade silicone mouthpiece. With appropriate use and maintenance, this water bottle can go for up to eight months before needing a filter replacement. Replacement filters are also available from Joypur.
The Joypur filtered water bottle also features a compass inside the lid, so it can point you in the right direction in addition to helping meet your hydration needs while on any kind of adventure.
In addition, the filtration capacity of this bottle makes it appropriate for filtering water from a wide range of natural sources like rivers, lakes, streams, etc., so it’s a perfect companion for hikers, backpackers, campers and other adventurers.
Reviewers point out that this bottle is a great on-the-go solution, especially if you’re traveling somewhere that has questionable water sources. Users like the wide range of water bottle colors and the ease of carrying around this lightweight bottle. Some users report difficulty getting the water to come up through the straw – it takes a great deal of suction. This bottle also gets high marks for the clean, crisp taste of the filtered water.
How Filtered Water Bottles Work
Filtered water bottles offer personal water filtration – you can put in ordinary, municipally treated tap water, or with some versions, water from a natural source like a brook or stream, and contaminants, pathogens, sediment, etc., are filtered out through the bottle’s filtration system. Most filtered water bottles use some combination of physical and chemical filtration. Depending on the specific design, some may filter water as it is consumed, while others provide filtration as the water enters the bottle. It’s important to note, though, that most filtered water bottles on the market are designed to work with already-treated municipal water – they’re best suited for removing taste and odor abnormalities associated with chlorine and other chemicals used as part of the water treatment process.
Physical filtration can remove sediment, dirt and other larger particles through a physical separation process. While the specific filtration mechanism may vary, most all filtered water bottles will use a carbon filter, which uses activated carbon, or activated charcoal, to separate impurities from your water.
When we say carbon is “activated,” that simply means that it’s been oxygenized, usually under high heat, so that it has a lot of pores, dents and uneven areas on its surface, which leads to adsorption – the attraction of molecules to the porous surface of the carbon. Pollutants, sediment, etc., in your water will be highly attracted to the carbon and remain adhered to it as the clean water passes completely through the filter. You’ll know if your water bottle uses activated carbon by the telltale, tiny black specks that can accumulate in the bottom of your bottle.
In addition to physically attracting and binding many contaminants, carbon also catalyzes several chemical reactions that further purify your water. For example, chlorine reacts with carbon, producing chloride ions. These ions bind to the carbon filter, which removes the chemical chlorine from your water.
Carbon-activated filtration is extremely effective – in fact, carbon has one of the highest levels of binding sites across all chemical elements, so this makes water filtration an easy task for activated carbon. Of course, once your carbon filter has gone through this process several times, your filter will have absorbed many chemicals, microorganisms and other contaminants that you want removed from your water – so you must replace the filter when recommended so that you protect the filter’s ability to attract and absorb contaminants over the long term.
Ultimately, filtered water bottles are extremely good at filtering out three harmful classes of contaminants: parasites and bacteria, chemical compounds and viruses. Chemical compounds – like fluoride, chlorine and arsenic – come in both organic and inorganic varieties and can reach your water by both artificial and natural means. If you’re interested in also ionizing your water, feel free to check out our Best Water Ionizer Reviews article, written just before this one.
Conversely, bacteria, parasites and viruses can be present in just about any type of water we encounter – whether from a bottle, a well or a tap. However, some of the most dangerous microorganisms are found in natural water sources like rivers and streams, making a filtered water bottle a must-have for those whose outdoor adventures place them in situations where drinking from a natural water source is a must. Make note, though, that filtered water bottles can’t match the purity levels of reverse osmosis disinfection, for example, but they can treat water to the same or higher levels of purity as what you’d find with typical bottled water.
Advantages of a Filtered Water Bottle
Using a filtered water bottle can bring many advantages, not least of which is that you no longer have to worry about buying bottled water when on the go. A small investment in a filtered water bottle now can reap huge savings over years of diminished bottled water purchases.
Whether you’re out and about running errands, filling up your water bottle after going through airport security, filtering out the taste of the water from your gym’s water fountain, or exploring an area of the world where potable water isn’t guaranteed, having your own personal water filter gives you the freedom and peace of mind that you can have purified, great-tasting water absolutely anywhere you go.
This not only saves you money, but it is also better for the environment. Using a filtered water bottle can save thousands of empty, single-use plastic water bottles from ending up in landfills across the globe, waiting the hundreds of years it will take for them to degrade. Using a filtered water bottle also helps save energy, since making plastic water bottles, delivering, storing and selling them, all use tremendous amounts of energy.
And – a refillable filtered water bottle gives you freedom. You can rest assured that wherever you go, you can make sure you have the pure, clean, safe water you need to stay hydrated. You don’t have to worry about finding stores along your adventure or packing enough water in advance to last the length of your trip. If you have a filtered water bottle with you, you can feel confident drinking water from just about any source – tap, lakes, rivers, wells, streams, etc. By its very nature, tap water is convenient, and if you add the extra step of filtering it with your filtered water bottle, you can combine convenience with the peace of mind that you’re drinking the safest water possible without adding to bottled water waste.
Many backpackers, hikers and adventurers have historically used disinfection tablets to make sure the water they drink is safe. A filtered water bottle offers a better option – these bottles work much more quickly, without the nearly two-hour wait associated with most disinfection tablets, and they can do more to address taste and odor issues, which tablets can’t fix. Filtered water bottles also offer benefits above and beyond using an ultraviolet light wand to disinfect water from natural sources; these work quickly, but they require batteries, which means you always must have enough on-hand. In addition, filtered water bottles are much lighter and easier to carry with you than hard pump filters, which many campers have traditionally used – they also work quickly, but they are extremely bulky and uncomfortable, both to use and to transport as you look for adventure.
Perhaps the most traditional and tried-and-true method for disinfecting water on the go has historically been boiling it – but boiling your water to disinfect it takes a lot of time and effort. Being able to drink right out of a filtered water bottle is much more user-friendly than having to start a fire, wait for water to boil, then wait for it to cool down enough to be drinkable.
Overall, using a filtered water bottle makes more traditional water disinfection methods obsolete – methods like UV radiation, boiling and hard pump filters are time-consuming and less effective than simply making sure you always have your filtered water bottle with you.
Filtered Water Bottle Maintenance
The most important piece of caring for your filtered water bottle is regularly changing the filter, as is the case with any filter, an example being refrigerator water filters. Make sure you understand your manufacturer’s specifications around how often/after how many gallons of water your filter needs to be replaced, and make sure you keep plenty of extra filters on-hand. Because your carbon filter is removing contaminants by chemically binding to them, you want to switch them out with ruthless regularity.
Most of the water bottles reviewed here are dishwasher-safe, though some require top-rack washing only. However, filters cannot go through the dishwasher, so make sure to remove those before sending your bottle through a wash cycle. Putting your bottle through a dishwasher cycle can fully sterilize both the inside and outside of the bottle, keeping it as safe for use as possible. But if your bottle is a stainless steel version, make sure to wash it by hand only – it should not go in the dishwasher.
Make sure you also fully understand the warranty conditions for your bottle – most manufacturers will replace bottles that break, crack or leak during the warranty period. Don’t continue drinking from a bottle that is broken or cracked – those breaks and cracks could let in the same pathogens your filter is working so hard to remove.
To prevent mold growth, you can reduce excess moisture by leaving the cap open when not in use as much as you can, and make sure to wipe down your bottle regularly. You should also make sure your hands are clean anytime you handle the straw, spout or mouthpiece of your filtered water bottle.
Best Filtered Water Bottle Buyer’s Guide
Naturally, there are several key points you’ll want to consider when determining which filtered water bottle is the best fit for you, and your ultimate choice will come down to personal preference. Below we’ve organized some of the top considerations.
Your Filtering Needs
What do you need your water bottle to filter out? Depending on your lifestyle and how you plan to use your filtered water bottle, this can vary widely, but you should be clear from the beginning what you’ll want to use your filtered water bottle for. For example, if you want it just to filter ordinary tap water while you’re out and about, you should be fine with a version equipped to deal with chemical compounds – like the Brita bottle reviewed here. But if you’re taking your bottle on around-the-world adventures, you’ll be much better off choosing a filtered water bottle that can deal with some of the more dangerous pathogens and contaminants you might encounter – something more like the LifeStraw or the GRAYL Ultralight. Think about how you’ll transport it, too – does it need to fit in a backpack? In a bike’s bottle-holder? Do you need to be able to hold it as you’re trail running?
Type of Filter
While most filtered water bottles employ activated carbon filters, you can also find those that use an ultraviolet filter instead – these bottles are typically more expensive to purchase and to maintain, since they’re powered by batteries. Bottles with UV filters – like the LARQ bottle, for example – are more effective at sterilizing water and removing viruses, but they aren’t as adept at getting rid of chemical compounds as those with activated carbon filters. In addition, you can also find filtered water bottles that combine both types of filter – activated carbon and UV. This gives you the best of both worlds and fully covers you against any kind of dangerous contaminant or chemical that might be in the water you drink.
If you’re globe-trotting, hiking and exploring, you want a water bottle that’s nice and light so that it won’t weigh you down. You also want something durable that won’t break or bend and can stand up to some rugged adventures. Many of the models we’ve presented here are made from BPA-free plastic, which works well. Others you may find are made of stainless steel, which, though durable, can get heavy at times, so make sure to keep that in mind as you make plans.
Water Delivery Mechanism
This is all personal preference – some bottles come with flip-up straw, like the Lifestraw model we reviewed here, but you might prefer a nozzle or a twist lid.
Ease of Maintenance
Make sure you’re choosing a filtered water bottle that’s easy to clean and has a filter that’s easy to switch out. This can help you ensure that the bottle is always performing at top capacity and that your water is as purified and great-tasting as possible.
Summing It Up
We hope you’ve enjoyed reading about the best filtered water bottles on the market; we sure enjoyed researching and compiling this article. There are so many reliable and high-performing unit available, you’re sure to find something that meets your needs and personal preference. And you don’t have to settle for just one. Depending on your level of activity, you may decide to try a couple of different models and switch them out for different situations. Whatever you decide, as we discerned while writing the above filtered water bottle reviews, going for a filtered water bottle is a win on many levels – it benefits your pocketbook, your health and the future of the planet.
