The Top 3 Best Filtered Water Bottles

There aren’t many activities quite as peaceful as hiking out into the backcountry, surrounded by nothing but nature. Outdoor adventures and activities are just as good for the mind as they are for the body, but a key aspect of health is staying well-hydrated by drinking water.

If you are venturing out into a familiar area or an area where you know there are water sources for you to drink, you can keep the weight of your pack down by skipping the numerous water bottles for a quality filtered bottle.

Here are 3 of some of the best filtered water bottles for outdoor enthusiasts.

Sawyer Filter Bottle

First up is Sawyer’s Personal Water Filtration Bottle. Sawyer is a well-known water filtration brand so it’s no surprise that their filtration bottle is fairly popular to get purified water and stay hydrated during your hikes. Those who are only going to spend a few hours outdoors or people who are doing a lot of traveling around North America and want the protection of water filtration will be happy with this bottle to get rid of all the contaminants in water.

  • BPA-free materials
  • Compatible with other hydration pack system

  • Removes 99.9999% of protozoa – including cryptosporidium and giardia
  • Meets EPA standards
  • Does not remove viruses

The Sawyer Personal Water Filtration Bottle does not remove viruses or chemicals, so it isn’t an all-in-one style of filter bottle. However, the vast majority of water sources in North America are largely free of viruses which makes this bottle safe for turning clean freshwater sources into safe drinking water. The other benefits of this bottle still make it a great choice.

Like many of Sawyer’s other filtration systems, this bottle can easily be maintained while in the field. In the kit you receive with the bottle there is a special backwashing syringe for this purpose. This syringe hardly takes up any space and can be stowed away in your daypack pocket in case you need to clean the bottle after you get purified water while out in the country.

The bottle’s size of 34 ounces is perfect for the majority of people. It holds enough that you won’t have to stop every hour to refill but also isn’t so large and bulky like the bottles that hols a couple of liters of water, that it’s unnecessarily heavy or cumbersome to hold in one hand. This bottle is designed as a personal water bottle, but a couple may choose to share or it can be used for a couple of kids to drink.

Another really cool feature of the Sawyer bottle is that the filter is attached to the cap of the bottle. The 63mm cap is a classic widemouth size which means it will be compatible with other similar-sized bottles. While the durable BPA-free Sawyer bottle works perfectly, it’s nice to have the option of using the filter on another bottle for whatever reason.


“I really like the design and size of this product. Nice to have on a trail hike or in an emergency situation if I find that I need drinking water and there is non-potable water. I pack coffee filters to strain out any sediment before filling the bottle if the source requires it.” by David Allen Beasley on Amazon.

“…Filled the bottle with normal tap water and drank from the filter straw and omg that was the freshest and sweetest water I ever drank in my life.
I thought it was psychological so I got my girlfriend to try it and she too agreed that the water was very fresh…” by Andy Toh on Amazon.

As mentioned earlier, North America water sources are essentially free of viruses and bacteria but this bottle will give you extra security and peace of mind, not to mention you can use it in other countries safely. As for chemical reduction, the filtration system helps remove bad tastes and any water turbidity that you don’t want to have in your bottled water.

Even though the Lifesaver bottle is a bit more on the expensive side when compared to other water bottle filters, it is money very well-spent for globetrotters or hardcore backpackers.


“This appears to do the job – of course I cannot validate the chemical analysis of the water but it tastes great and looks crystal clear. The process of filtering is a little tedious but for what it is designed to do that is not even an issue. This little bottle can save lives – I plan to do quite a bit of desert travel and this will be going with me. Its well constructed and should last a long time.” by Aussieonyak on Amazon.

“If you are in jam with no clean water around, this little bottle can be a life saver. Be sure to try it out, prime it and flush out the charcoal bits before using it. Then, once used, keep it moist or count on buying replacement filters.” by USPSA_Guy on Amazon.

“I actually have two Grayls – a stainless steel one and the one shown – a lighter weight plastic BPA-free bottle. I have used both on my travels and have drunk water from all kinds of places without any problems.” by Piz on Amazon.

“I was going to Cuba and thought about purchasing a water purifier in lieu of having to buy plastic bottles of water. I read a bunch of reviews and it seemed like the GRAYL was the best choice although it seemed expensive. Then a friend told me she had taken this to Africa and drank out of a river without getting sick! I immediately bought it. Another friend pointed out that the GRAYL would cost more than bottles of water for the whole trip which made sense but I have no regrets. ” by Penelope on Amazon.
