The 6 Best Backpacking Water Filters of 2023

We tested backpacking water filters and treatment systems from Platypus, Sawyer, Katadyn, LifeStraw, and others to find the best option for your adventures

Our filtration gurus have bought and tested 43 of the best backpacking water filters over the last 11 years. This updated review covers 26 filters and treatment systems. We tested these filters extensively on various adventures, from climbing trips in Peru to running expeditions across the USA to fastpacking adventures in Iceland. We evaluate portability and ease of backcountry maintenance in the field while also investigating critical aspects such as what each model removes from the water and the amount of time it takes to process one potable liter of water. We are confident in offering any backcountry traveler our insights and recommendations based on our comprehensive field and objective in-house testing.

When it comes to backpacking, having the right gear makes all the difference. Whether you're in the market for a new pack, some solid footwear, or a compact cooking system, rest assured we have recommendations for you. From tents to base layers, you'll be ready for the backcountry in no time.

I carry bottles of water, but I also have a Sawyer squeeze water filter. Also, if it’s cold, make sure you sleep with your water filter in your sleeping bag, so it doesn’t freeze.
