The 6 Best Water Bottles with Filters for 2021

Everyone loves a “buy it for life” product—something you can rely on for decades. A good filtered water bottle can definitely fall into this category if you take the time to make a well-informed decision about what you’re buying. Thanks to replaceable filters, a well-made filtering water bottle will last you as long as the housing stands up! 

The trick to finding a great water bottle filter is looking at the key elements that make it a quality investment. First, consider the housing—durable plastic and aluminum tend to hold up better than glass or cheap plastic. Next, consider filter size and capabilities—after all, this is why you’re buying a water bottle with a filter. Finally, consider the filtration rate and filter lifespan, to understand the ongoing cost of this investment. 

There are dozens (even hundreds) of water bottles with filters out there to choose from. Save yourself the trouble of comparing them all. Instead, check out our list of the six best water bottles with filters for 2021.

1. Aquaspace® Survivor™ Travel Water Bottle with Filter

The ultimate water bottle with a filter, the Survivor™ from Aquaspace® is designed to go anywhere and purify water no matter what freshwater source it’s from! It’s rugged enough to take on your next camping trip and convenient enough to use throughout the day at home. 

With 20oz and a filter media lifespan of 2-3 months, users can expect to get as many as 288 refills out of this bottle. It’s one of the more expensive bottles on this list, but it’s number one for a reason: there’s no matching the superior filtering capabilities it offers. The Survivor™ will remove 99.99% of bacteria, parasites and cysts, as well as other common contaminants like lead, chlorine, herbicides, pesticides and VOCs. 

2. LifeStraw Go Water Filter Bottle

Another popular favorite for outdoor enthusiasts and those on-the-go, LifeStraw water bottles are known for their strong filtering abilities for things like bacteria, parasites, microplastics, chlorine and organic chemical matter. At 22oz, it’s also a good size for an on-the-go water bottle. The carbon filter is good for up to 26 gallons—about three months. Its second microfilter lasts up to 1000 gallons.

LifeStraw is great for organic filtering, but leaves a little to be desired when it comes to filtering lead. It’s another filter water bottle with a higher-than-average price point, but its capabilities are worth the investment in clean, safe water. 

3. SurviMate Filtered Water Bottles

Designed primarily for outdoor enthusiasts and hikers, SurviMate filter water bottles work similar to LifeStraw in that they use a carbon filter, coupled with a microfilter. It’s highly effective at getting rid of bacteria and microbes, chlorine and other dangerous chemicals. That said, it doesn’t tackle led or VOCs like some of the other survivalist bottles on this list. 

The best thing about this bottle is the value. At a <$50 price point, it offers some of the superior filtering capabilities of higher-end filter bottles, without breaking the bank. The ~400-gallon filter lifespan is a little suspect, but it’s widely review and well-respected as one of the better mid-range filter bottle options on the market. 

4. Aquaspace® AquaBuddy™ Water Bottle with Filter

For those seeking an everyday water filter bottle with great capacity and a no-frills design, it’s hard to beat the AquaBuddy™ from Aquaspace®. It’s a less-intense version of the Survivor™ bottle that tops this list—perfect for those who need an everyday bottle with superior filtering capabilities. With 20oz and a filter media lifespan of 2-3 months, users can expect to get as many as 288 refills out of this bottle

What sets this filter bottle apart from others is that it’s an alkalizing water bottle—meaning it has the ability to raise the pH value of water to roughly nine. It features Aquatomic® Hydrating Magnets that de-cluster water molecules to improve water’s bioavailability. The result is better hydration. It’s also a soft-squeeze plastic bottle—a welcome differentiator from hard plastics on this list. 

5. ClearlyFiltered Tritan Filtered Water Bottle

Featuring a huge 24oz capacity, this filter water bottle offers filtration capabilities for more than 220 contaminants. Its filter is one of the best on this list, with a lifespan of 2-3 months and filtering capabilities for up to 25 gallons. Part of the reason this filter is so well respected is because the company, ClearlyFiltered, producers an array of filtration products, not just water bottles. 

This bottle is slim and easy to grip, and features a comfortable mouthpiece—the construction of this bottle has net it high reviews among filter bottles. That said, the filter itself can be a little clunky and is part of the reason for the bottle’s larger size. It’s also clear, so you can always see how much water you have left.

6. GRAYL Ultralight Water Purifier

The filtering system of the GRAYL Ultralight water filter bottle is something of a novelty. Instead of letting water sit to purify or sucking it through filter media while you drink, this system involves physically pushing water through the medium. This system offers clean water on demand, whether in your home or out in the wilderness. The filter has about a 40-gallon lifespan and is capable of removing waterborne pathogens, chemicals, heavy metals, plastics and more. 

The design and function of this bottle might take a little getting-used to, but it’s a great solution for those who want the option to carry an empty bottle and hydrate on-demand. The only real downside is that the bottle is only 16oz capacity, which means more refills that can quickly dampen filter life. 

Each of these filtered water bottles represents a great investment—one you’ll appreciate every time you use it. More important, they represent a long-term investment in your health and wellbeing. Take a moment to check out these six water bottles with filters, look at their specifications, check out the prices and make a decision that works for you. Remember, this is something you should use each and every day—make an investment that counts!
