Any survivalist can tell you that having a safe water source is one of the most important things to consider when heading out on a camping or backpacking adventure. Car campers can just carry jugs of water from home, but when you get further afield, carrying becomes impractical since water is extremely heavy. Drinking water from unknown sources is never a good idea, especially when you’re far from civilization and medical care.

Enter portable water filters. They let you carry a device for purifying water so you can use those wild sources of hydration without worrying about contamination. We rounded up our top backpack water filters across several categories so you can find the right solution for your adventures.
