We’ve used just about every type of filtration and purification method available in our 20,000 miles of hiking over the past decade. From brands like Sawyer, Katadyn, Platypus, Aquamira, and more, we tested for water quality, maintenance and longevity, treatment time, weight and packability, and ease of use. Whether you’re looking for ultralight filtration for your next big adventure or a reliable purifier for overseas travel, our team of experts will help you find the perfect water treatment for your needs.

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.
