We’re always asked what we do about water when we’re out doing what we do. It’s simple: we treat it. Here are two systems worth a look.

The Sawyer Mini weighs just 2 ounces, is small enough for a pocket and removes 99.99999% of all bacteria and protazoa. Plus, it’s good for 1,000 gallons.Brandon Mathis

Treating water when you’re in the field doesn’t mean you have to stop and pump and clean and hassle with heavy and cumbersome tubes and containers. Today, it’s easy to filter on the go.

Sawyer Mini– $20

Sawyer is standard issue in the backcountry around the world. Its small size, two ounces, its small cost, $20, and its filtering capabilities make it the go-to for hikers, runners, hunters and others. It self cleans with a simple backwashing flush method, and even though the flowrate might be a little low, this thing is good for 100,000 liters of water. With an included straw, it can be used to directly drink water from the source, it comes with a burly collapsible water pouch, plus it can fit any standard 28 mm threaded water bottle out there.

Sawyer Select $60-$90

Sawyer’s Select S1 system can remove 99.99999% of bacteria and protozoa plus chemicals and pesticides, and helps filtered water taste better.Brandon Mathis

By using a special bottle with a foam core that attracts contaminate molecules to adhere to its surface–something Sawyer calls adsorption filtration technology–Select Filters go beyond filtering bacteria and protozoa. It also purifies by filtering chemicals pesticides and viruses. Other Sawyer Select systems can remove heavy metals and viruses.
