Best Portable Water Filters for Hiking

Our Best Water Filters for Hiking / Camping Reviewed

Whether you’re hiking a ridge in Zion National Park on a scorching summer afternoon or an alpine trail outside Zermatt on a cool autumn day, proper hydration is a must. The problem is carrying enough water into the wild with you can be a significant burden. Each liter of water weighs more than 2 pounds and on a strenuous day long hike during the summer you may need to drink 4 or even 5 liters of water. Meaning you’ll have to carry 8 to 10 pounds of water. That much weight will turn an already arduous hike into a slog of Olympic proportions. What you need is a way to purify the available groundwater to protect yourself from the bacteria, protozoa and viruses lurking within, waiting to turn your intestines into jelly. What you need is one of our best Portable Water Filters for hiking.
