The Best Hiking Water Filters (Review & Buying Guide) in 2021

A hiking water filter is essential if you’re an outdoor enthusiast.

Anyone who spends a significant amount of time outdoors knows that one of the most important things you can bring is drinkable water. Staying hydrated is at the top of any camper’s, hiker’s, or sportsman’s priorities. Odds are water is also one of the heaviest things you’ll carry. The longer you plan to be on the go outdoors, the more water you’ll need.

One way to cut down on this weight is to bring a hiking water filter. These portable water systems turn murky water from ponds, streams, and lakes into clean, safe drinking water. They’re compact and light enough for even a daypack, and we wouldn’t recommend hitting the trail without one. Take a look at the list below to see what’s available and find the best hiking water filter for you reviewed by Zach Faulds.
