Best Filtered Water Bottle Reviews 2019 (Updated)
1. Sawyer Personal Filtered Water Bottle
BPA Free Bottle
0.1 Micron Absolute Filtration
What We Like
Sawyer’s personal water bottle looks like your standard sports bottle. Its flip-top is convenient, the plastic outer shell is durable, and it holds 34 ounces of water. High filtration levels via a .1 Micron filter removes 99.9999 percent (or more) of common bacteria, protozoa, and more.
The filter also promises up to 100,000 gallons of filtered water, which is an impressive lifespan. Clean and reuse it—no replacement cartridges necessary, ever.
You just fill the bottle, then start drinking—the water is filtered as it passes through your drinking straw. And the included filter is compatible with hydration pack tubing or standard bottles. Its versatility is practically unmatched.
What We Don’t Like
While the filter can be reused “almost indefinitely,” according to Sawyer, you won’t know that it needs a cleaning until the water flow slows down. Then, you use the cleaning plunger to “backwash” the filter to clear out the gunk.
Also, some people prefer non-straw bottles—this one won’t be for you if you prefer fast-flowing open-top bottles.
And finally, looks are not the Sawyer bottle’s super strong suit… Of course, looks are subjective!
Looks aside, we love everything else about the Sawyer bottle. Even if it’s frustrating to have to clean the filter, it’s amazing that it will last for years.
With third-party testing confirming how effective the filtration is, you can safely drink from endless water sources—and carry 34 ounces of hydration with you wherever you go.
2. GRAYL Ultralight Filtered Water Bottle
BPA-Free 100%, Food-Grade Silicone
ion exchange, ultra-powdered activated carbon
What We Like
GRAYL’s ultralight water purifier bottle comes in a handful of fun colors and is easy to drink from. Its single-press design is a simple way to filter and then sip your water quickly.
To get fresh water, fill the outer cup, insert the filter portion, press down, and your water is filtered through the cartridge. The screw-on lid eliminates the need to slurp or bite to access your water, too.
The filter removes 99.99 percent of common viruses and bacteria. It also gets out particulates, chemicals, heavy metals, and other gross stuff. And each cartridge can filter around 40 gallons of water—that’s two to three months’ worth of water.
GRAYL’s three-part filter technology is so effective (results via third-party testing) that you can drink water from nearly any source—like open streams, rivers, and more.
What We Don’t Like
It does take some muscle to press down on the top of the filter cup. You might struggle to push the water through, especially as the filter gets more use (trapping more particles). The replacement filters can also be a bit tough on your budget if you use the bottle a lot.
With a little bit of pressure, you can quickly filter water from any fresh source with the GRAYL. Its filtration power is impressive, even if it takes a bit of muscle and a few minutes of your time.
With replacement filters, you can keep using this bottle for many years of clean drinking water.
3. Epic Nalgene OG Water Filtration Bottle
100% BPA/BPS-free Tritan Material
Epic Urban Filtration
What We Like
If you’re already a fan of Nalgene, this bottle needs no introduction. If you’re not, we’ll break it down:
Nalgene is a USA-made product that’s super durable and easy to clean. The filter system is from the company Epic and is interchangeable with other Nalgene bottles, making it versatile no matter how many bottles are in your collection.
And that filter removes over 200+ known water contaminants, confirmed via third-party laboratory testing. Plus, a handy loop gives you a way to grab the rather bulky 32-ounce bottle.
We also like that Epic makes their filters in the US—and they’re recyclable, too.
Although Nalgene is a big proponent of outdoors adventuring, the OG bottle doesn’t come with an outdoor water filter—only one for tap water (the “urban filter”).
To safely purify other water sources, you’ll need to purchase the filter that removes outdoor water contaminants. We like that both options are available so you can pick what suits you.
What We Don’t Like
Nalgene also notes that its Epic Urban filter is comparable to 550+ plastic water bottles. That estimate gives each filter a life of about 70 gallons, which isn’t as impressive as other options.
There’s also the fact that the bottle uses a straw filtration system. The sipping action pulls water through the filter, which can be a bit more time-consuming than sipping from pre-filtered water.
Nalgene is a well-loved brand you can trust. Plus, their water bottle has a large capacity, an effective filtration system whether you’re at home or on the trail, and you can swap the filter to any Nalgene bottle in your stash.
4. LifeStraw Go
advanced 2-stage activated carbon filter
Hollow fiber microfiltration membrane with activated carbon filter
What We Like
LifeStraw’s water bottle looks a lot like the Nalgene option, but it holds a bit less (23 ounces). However, the strap and carabiner are a welcome addition to this stylish bottle. You also have a ton of color and pattern options, which means everyone in the family can choose their design.
Two-stage filtration removes waterborne bacteria, protozoa, and reduces chlorine and other nasty flavoring. The first filtering stage handles up to 4,000 liters—or 1,000 gallons—of water.
We also love that for every product they sell, LifeStraw helps children in need access safe water for an entire school year.
What We Don’t Like
LifeStraw’s filtration system is, of course, a straw type, which isn’t the right fit for every person.
The two-stage system is effective, but it also requires more frequent replacement. The activated carbon capsule only filters up to 100 liters (about 25 gallons).
You may also notice that the filter loses its effectiveness if it dries out—it’s best to use this bottle daily to keep everything working right.
If you’re in the market for a stylish, straw filter water bottle, LifeStraw’s might be the perfect fit.
It holds an adequate amount of water, filters waterborne hazards out of your bottle with a sip, and the company donates to kids in need. It’s a win-win-win!
BPA-Free with Leak Proof Lid
Brita Longlast Filtration System
What We Like
Brita’s sport bottles come in a two-pack that’s convenient and helps you get cleaner, tastier water. The bottles are dishwasher safe and include a built-in carrying loop. The squeeze-bottle style makes it easy to drink out of these since there’s no slurping involved.
There’s also no complicated filter changing or finagling with Brita—just swap out the filter, rinse the new one, and pump 20 ounces of water through it before drinking.
If you’re hoping to cut costs related to purchasing drinking water, these bottles can make your tap water safer and tastier for inexpensive sips straight from the tap.
What We Don’t Like
The filters do need to be replaced about every 40 gallons or two months. That’s not too high in comparison with other water filtration bottles.
While we like the squeeze function of this bottle, the spout (complete with a clear plastic cap) is a bit outdated in style and performance. The 20-ounce capacity is also relatively low. Still, the two-pack is a budget-friendly option that helps you stay hydrated all day.
Filtration helps make city water taste better, sure. But note that this isn’t the ideal product for filtering river or other natural water sources.
How to Pick the One for Your Needs
The right product for you will be easy to use and effective at filtering out the stuff you don’t want in your water. Here’s how to pick the best water bottle with filter for travel and more.
The first vital feature of a good water filter bottle is that it cleans water effectively. You want to remove protozoa, bacteria, viruses, chlorine, lead, and other contaminants from your water source. From city water filtration to higher-level filters that make natural water sources safe to sip, a good filtered bottle will do one or both very well.
You’ll also want a bottle that suits your lifestyle. However and wherever you travel, exercise, and hydrate will affect what constitutes a “good” water filter bottle. The best bottle is convenient and easy to use, though what’s easy for one person may not be for another.
For many people, style might be a concern. Especially if you’re buying multiple bottles for kids or other family members, a variety of colors and styles might be appealing. After all, drinking water doesn’t have to be boring. Or, perhaps you don’t care about looks at all and instead focus on the other features—which is fine, too.
Compatibility across multiple bottle types is a nice addition to many brands’ bottles. Nalgene, for example, ensures that its filtration device works with all other wide-mouth bottles in their product line. Sawyer’s filter fits in their bottles plus other standard water bottles and even hydration bladders.
And finally, the replacement rate of the filters is crucial, too. How long the filters last determines your cost-per-use of the bottle you buy. If they’re expensive, you may not be saving money by buying a water filter bottle in the first place.
Some bottles offer reusable filters, while others are easy to find in stores and may even be recyclable. Pay attention to how many liters or gallons a filter can handle and shop accordingly.
Considerations Before You Buy
Here’s what to think about before you purchase a new water filtration bottle.
Figure out what filtration level you need. Depending on your lifestyle, you may need heavier filtration than bottles intended for tap water.
Think about where and how often you drink water. For example, a glass water bottle with a filter isn’t the best choice for someone who is active outdoors. In contrast, a durable, BPA-free plastic bottle is ideal for people who enjoy rugged hikes and camping.
Consider capacity. How much water do you drink every day? How much should you drink in a day? Maybe you don’t get the opportunity to fill your bottle often, so a larger capacity is necessary. Or, perhaps you don’t want to carry a full 34 ounces around all day, and a 20-ounce capacity product would be handier. Think about your habits and shop accordingly.
Determine how you drink. Water filtration bottles come in a few types. There are spout-top bottles, squeeze options, straw filtration systems, and even press-down filtration styles. Choose one that fits your physical capabilities and hydration needs.
Advantages and Disadvantages
Water filter bottles are a smart choice for many people. Whether you live in a city with gross municipal water or want to ensure your safety while traveling abroad or adventuring in the woods, there are many advantages and a few disadvantages to bottles with water filters.
The advantages of a portable water filter bottle are plentiful:
· Clean, safe water, no matter where you travel.
· Can refill (for free) anywhere—from municipal sources or freshwater (depending on the filtration level).
· Cheaper than bottled water.
· Easier to use than faucet or whole-house filtration systems.
· It’s easy to replace the filters—just swap, rinse, and go.
· Avoid contaminants and disease-causing bacteria and viruses.
· Have a safe water source while camping, in emergencies, or if the power goes out.
· You’ll drink more water since it’s convenient and accessible.
· Makes tap water taste better by removing chlorine, lead, and other minerals, metals, and more.
· Can bring one on flights or other long trips for clean, tasty water wherever you go.
· May help you avoid illness in foreign countries or while traveling.
· You can filter only your drinking water and leave the tap open for washing dishes, watering plants, and other tasks.
· No installation required—just open your bottle and drink.
· You don’t have to remove and take anything with you, for example when moving after installing a whole-house filtration system.
There are a handful of disadvantages to water bottle filters:
· You can’t share (much). Bottles are for individual use unless you want to share germs with friends or family.
· When you need to replace or clean them, the water flow can stop without warning.
· Replacement filters (if necessary) can be costly.
· Different types of filters help with various contaminants—you need the right ones for your water source.
· Some systems can be hard to drink out of (like many straw types).
Is a water bottle with a built-in filter right for you? Here are some FAQs (and answers) on the subject.
1. How to Filter with this device?
How you filter the water with your bottle depends on where the filter is and how it works. On some bottles, the filter is below the spout, so your water filters as you drink it. Other bottles filter as you fill them. Read the label carefully to determine how to use the filtration function properly.
2. How Clean is Water from the bottle?
The cleanliness and safety of the water depends on the quality of the liquid you pour in plus the level of filtration the device offers.
· Third-party testing confirms how effective filters are at getting chemicals and other harmful stuff out of the water.
· Some filters are only for tap/municipal water, not natural sources of water.
· Water can still have a funny taste or even make you sick, depending on what is in it. You should never drink water that could be contaminated beyond the capabilities of your filter bottle.
3. Can I use this on water from a Lake, River, etc.?
Yes, many water bottle filters can handle filtering lake, river, creek, and other types of water. But, it’s crucial that you follow the manufacturer’s directions as far as what filter to use for what kind of water source.
Some manufacturers offer tap water only filters. Others offer both municipal water filtration and natural water source filters. Check the label or manufacturer’s website if you’re unsure.
Of course, the bad news is: you can’t filter saltwater.
Unless you have a purification system to remove salt and other minerals from the water, drinking seawater is still a no-go.
When looking for the best water filter for your money, it’s crucial to think about what features best fit your needs. Whether you prefer drinking from a straw or a spout, what type of water you drink most, and how you spend your days can all influence the decision.
But overall, the top focus of your purchase should be:
Fortunately, you can meet all three points with the Sawyer Personal Water Bottle Filter. Its filter is practically endlessly reusable—just wash and replace—and the filtration is top-notch. You can drink from natural water sources or the kitchen tap, enjoying over 100,000 gallons of clean drinking water with each bottle.
