Best Backpacking Water Filters 2021

When you’re out hiking, clean water is important. In the wilderness, there’s plenty of water to be found, but it’s not necessarily clean. There are so many different bacteria, parasites and viruses that live in rivers, streams, and puddles, that you can’t just fill a water bottle with it straight away.

That’s why you need one of the best water filters for backpacking. I’ve done all the research and narrowed down to the Best Ultralight Water Filters for Backpacking in 2021.

Hi there, I’m Brad McCartney from Australia. I set up BikeHikeSafari to document my life as an Adventure Cyclist, Hiker, Photographer and Nature Lover. Somehow it turned into so much more than that and is now a resource for all thing Hiking, Backpacking, Thru Hiking, Bikepacking and Bicycle Touring. With a combination of hiking gear reviews, gear lists, info on hiking trails and bicycle touring destination guides.

I started this website by accident after suffering from Chronic Fatigue Syndrome. I quit my career as a Police Officer and followed my dream to cycle and hike the most amazing places on the planet and was looking for some way to document my journey.

My only complaint is that eventually, backflushing won’t be enough. These can clog up after some time and no amount of back flushing will fix its low flow. I went through 2 on the AT. However, it will attach to Smart Water Bottles and most bladders!

Built for backcountry reliability and portability, the Sawyer Squeeze filter is our pick for the best portable water purifier.

The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).
