Best Gravity Water Filters of 2021

Most of us know by now that “clean” drinking water isn’t quite as clean as it seems. The EPA regulates more than 80 contaminants that pose a health risk – but these chemicals, metals and plastics can legally still be in our water in trace amounts.

What’s more, there are many emerging contaminants that aren’t regulated at all.

If you’re inclined towards choosing a gravity filter to treat your water, I’m here to help you find a system that’s best suited to your needs.

With 140,000 monthly readers and articles published by the likes of WQP Magazine and Sawyer Products, I make all aspects of water filtration my business.

In this guide, I’ll be sharing:

  • The top 10 gravity filters of 2021
  • 6 things you need to consider when buying a gravity filter
  • My answers to your most commonly asked questions

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).
