The Best Backpacking Water Filter Review

There was a time you could scoop up fresh mountain stream water on your hike and relish the sweet taste. Not anymore. In the 21st century, to stay healthy on your hikes in the wilderness, you have to treat all water as suspect.

Crystal clear mountain streams may seem clean to the eye, but millions of invisible micro-organisms are thriving there. Most living things in water are harmless, but there are types that can make you very sick when ingested.

Yes, if you’re in a survival situation facing dehydration, you’d take a chance and drink the water, as is. However, if you have a water filter with you, you can avoid a lot of intestinal discomfort.

There are many excellent backpacking water filters, and how they work and their simplicity will be important considerations when choosing the best hiking water filter.

You’re Not Alone

In the modern, over-populated world in which we live, no matter how remote your hiking trip is, somebody has no doubt been there before you. You can never tell whether further upstream people haven’t urinated or defecated into the water. You also can’t tell if a dead animal is rotting upstream.

Water filters vary in the types, as well as the number of organisms they are able to filter. The best backpacking water filter is small and compact and fits easily into your backpack. When you want to travel light with your backpacking trip, you can’t be carrying a daily ration of 4 liters of water with you. The best backpacking water filter is, therefore, lightweight and easy to carry around and has certainly revolutionised hydration issues of backpackers.

There are plenty of variations available, and we look at some reliable, robust water filters that can be easily popped into your backpack for easy retrieval:
