How We Picked

Reusable water bottles are great for cutting down on your plastic waste while still ensuring you stay adequately hydrated no matter where you are. But, sometimes, you need more than just a way to carry around tap water. Bottles that also filter or purify water ensure that you are drinking safe, refreshing water. And when you are traveling, backpacking, or away from reliable sources of water, you need to know that what you are drinking is free from water-borne diseases, too.

Filtered water bottles all remove contaminants from your water. How much they can remove depends on the type of filter they utilize. These range from simple, single stage, activated carbon filters that eliminate odors and chlorine to more complex ones that can remove microscopic contaminants that may make you sick.

To choose our list of the top ten best filtered water bottles, we explored tests from industry leaders, online reviews and ratings, customer reports, and manufacturer’s specifications. We compared each of our criteria and compiled a list that includes nothing but the best for those looking for a filtered water bottle. From inexpensive, single-stage filtering bottles to systems that can purify even the dirtiest of water sources, there is a water bottle on our list that meets your needs.

Katadyn BeFree 1.0 Liter Water Filter Bottle on a bike trip

Thy Katadyn system is unique in how it filters the water, too. While this filter purifies as you drink, you get a faster flow rate than other straw-type filters but with the same purification levels.

What We Like

The Katadyn system is adaptable and versatile in many different ways. The cap that is included is a flip-top, sport-style version that makes drinking easy. But it is not leak-proof, unfortunately. Because the threads on this bottle are a standard size, though, you can simply replace it with a standard soda bottle cap for a leak-proof top.

The one-liter bottle holds plenty of water for a day hike, but you can easily use it to fill a larger hydration bladder using standard components, too. The large mouth on the flask makes it easy to fill from streams and other sources, including from drips or rainfall. The filter will last a long time, giving you over 260 gallons of fresh water before you need to replace it.

The other thing we like about the Katadyn filter is that it is easy to clean. Whereas other filters require lots of blowing or the use of special tools, you can clean this filter by merely shaking a flask full of clean water for a minute or so.

Overall

Backpackers and trail runners will love the Katadyn BeFree 1.0 L Water Filter Bottle for its light weight, ease of use, long-lasting filter, and compact design. When compared to its competitors, it surpasses the mark in nearly every way imaginable. And because it is still a reasonable price, you will want to make it a part of your camping and hiking gear soon.

Because you can squeeze this bottle, you can actually use it to filter water to fill other containers, too, making it great for two people to use, as well.

What We Like

Like all Berkey’s products, this water bottle is sturdy, despite its squishy appearance. The filtering mechanism hangs inside from the bottom of the straw, but this design stands up to heavy use and the inevitable bumps and bruises of travel and outdoor use. You can use it on municipal water and backcountry water sources equally well, and it will consistently deliver refreshing, clean-tasting results.

It is easy to use and provides sufficient flow when drinking. It is comfortable to carry and also includes a convenient carrying loop.

Buyer’s Guide to Finding the Best Filtering Water Bottle

Filtering Capabilities

When you are purchasing a filtering water bottle, you need to know what type of water sources you plan to filter before you purchase. Some bottles can only filter water, while others can purify it. The difference is filtering is just removing unnecessary compounds while purification removes those contaminants that can make you ill or even kill you.

If you are going to be filtering just tap water, which is already purified, then you don’t really need a purifying filter, but if you plan to travel to underdeveloped areas of the world or use your bottle while hiking or backpacking, then you will want the ability to clean any water source and make it safe for drinking.

Capacity of Container

How much water your bottle can hold is an important consideration. The smaller the vessel, the more often you will need to fill it and filter your water. If your bottle only holds a few cups of water, can you use it to filter and then fill another, larger container, or a hydration bladder? Depending on your hydration needs, you may want to opt for a larger bottle that holds more water.

Quality of Materials

If you are planning to travel with or use your water bottle while outdoors, you will want to be sure it is made from materials that can withstand heavy use. Impact-resistant plastics, sturdy components, and leak-proof lids are all good to have when you are on the move. Look for manufacturers with an excellent reputation for reliable products and for those who guarantee their materials.

Lifespan and Cost of Filter

The filter is the one part of your water bottle that is designed to wear out. Knowing how many refills you can get from each filter, as well as the cost of replacement will help you determine the value of using your water bottle over time. Those with longer-lasting filters are great for when you will not have access to new filters easily, such as while traveling long-term or while thru-hiking.

Weight

Backpackers and travelers are always conscious of how much weight they can carry with them, and some bottles are more substantial than others. If you are just taking your water bottle to the gym and back, you may be less concerned with weight, though this may still be important to you.

Frequently Asked Questions

Q: How does a filtering water bottle work?

A: Each water bottle on our list works a little bit differently, so you will need to read the manufacturer’s directions before use. In most cases, you simply fill the bottle, and the system filters the water as you are drinking. Your sucking motion pulls water through the filter, which removes contaminants before they can pass into your body. A few of the bottles we have listed actually filter the water first and then store the clean liquid in the vessel.

Q: What is the difference between filtering and purifying?

A: While all the bottles on our list will filter water, only a few purify it. While filtering removes unwanted materials that influence the taste and odor of your water, purifying actually makes your water safe to drink. If you know your tap water is already safe to drink, then filtering is enough to make it taste better. If you are unsure or if you are drinking from natural water sources like streams and lakes, then you will need to purify the water to remove disease-causing microbes.

Q: Do I need to clean my filter?

A: Not all filters need to be cleaned after each use, but those that are designed to purify and treat dirty water sources need to be cleaned each time you use them or sediment can quickly clog the filter and shorten its lifespan. Your filtering water bottle will come with directions for how to care for your filter, and you should read and follow these closely. While some require specialized tools for cleaning the filter, others just need to be blown out or shaken to remove built-up contaminants.

Q: How should I clean my water bottle?

A: It is important that you keep your water bottle clean after each use, and while some of the ones on our list can be placed in your dishwasher, all can be safely cleaned using soap and water. Be sure to wash and thoroughly dry your water bottle between uses and to follow your manufacturer’s directions about cleaning and storing your filter when your water bottle is not being used.

Q: Can I put my filtered water bottle in the refrigerator?

A: It is safe to place your water bottle in the refrigerator, but nearly all the bottles on our list caution against freezing the filter itself. If you are camping in areas prone to freezing, you will want to protect your filter from these colder temperatures, or it will be ruined and require replacement.

Q: Can I use my filtered bottle to fill another container?

A: While some bottles can be used as a pass-through filter, others cannot. Those that require sucking to draw the water past the filter cannot be used to fill another container, such as a hydration bladder or a partner’s water bottle. Others, including those that you squeeze or that use another filtering mechanism, can filter water that can then be poured into another container. If this is important for you, be sure to read the directions for use before purchasing.

Conclusion

Having access to safe drinking water is imperative, and when you purchase a filtered water bottle, you can feel safe knowing that you are removing harmful pollutants to your life-giving water. Whether you just want to improve the taste of your municipal water or need to purify contaminated sources around the world, there are many filtered water bottles that can meet your needs.

Our list of the top ten best filtered water bottles includes choices for the budget-conscious, those concerned with emergency preparedness, and every type of traveler and outdoor enthusiast out there. Water filtering systems continue to improve and get easier to use, so there is no reason that safe, great-tasting water can’t be a part of your life.
