Review: Best Portable Water Filters

No matter what adventure you plan on undertaking, you will certainly require water to fuel your efforts as you undertake it. Although sparkling mountain streams and rushing creeks typically appear crystal-clear and pure, be aware that they can often harbor dangerous organisms and particles that can quickly turn your adventure into a nightmare. The best way to avoid this microscopic slew of unwelcome hitchhikers is to arm yourself with a water filter or purifier. Both have the ability to fight against bacteria and protozoa, but only a purifier can fight against viral threats. It is a good idea to do your homework regarding the water quality in the area you intend to explore so you can prepare accordingly. Below are some of the best choices for a portable water filter based on filter quality, efficiency, and reliability. Top performing purification tablets were also included in this list to assist those who desire the added protection against viruses.

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).
