Best Water Filters of 2021 – Reviews & Guide

Public drinking water supplies are teeming with more than 90 chemical, microbial and radiological contaminants, many of which pose a serious health risk. I’m not surprised if you want to remove these contaminants from your water as quickly and effectively as possible.

I’ve been working in the water filter industry for nearly a decade, writing for WaterFilterGuru.com and other key water industry publications, including HowStuffWorks, Water Quality Product Magazine, Water and Wastes Digest Magazine, Sawyer Products.

When there are so many water filters available nowadays, a filter has to offer something really special to make it onto this list. After so long in this industry, I’m well aware of the products that are consistently favorites amongst customers, based on reliability, performance, contaminant removal capabilities, quality of construction, filter capacity, and much more.

In this guide, I’ve shared:

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).
