We tested filters from Sawyer, Katadyn, LifeStraw, MSR, and more to find the best option for every adventure.
Watch videoOnce upon a time, you didn’t need such a newfangled contraption as a backpacking water filter. Getting a refreshing drink meant dipping your tin Sierra cup (or Nalgene) in any stream and taking a nice, cool, clear drink. The good news is that if you can find a spring, that still works. Unfortunately, the water most of us encounter backpacking may well contain giardia and other fun protozoa and bacteria that can quickly ruin your trip.
Thankfully, the solution is pretty simple. Grab one of these water filters and put it between you and that ice-cold stream. Many of the filters we’ve tested aren’t much more complicated to operate than dipping a cup in a stream. In fact, our first two picks allow you to do pretty much that, drinking clean, cool water almost straight from a stream.
