Safety: All Sawyer Water filters exceed EPA and NSF recommendations for removal rates.

Flow Rate: The rate and capacity at which you can treat field water is very important to the quality of your outdoor experience- or in the case of the military, your safety may be at stake. Quite simply, the flow rate of both Sawyer’s Water Filter and Water Purifier are amazing. They offer virtually no resistance until they near the end of their cycle. Just Drink™. These Sawyer Filters can handle 40 PSI, which means you can also hook them up to full faucet pressure. The resistance is so slight you can hook them up to a gravity feed system to yield 5 gallons of treated water in less than 30 minutes. You also apply pressure to increase the flow rate. Or you can Just Drink™. Simply amazing, so simple it will change the way you think about treating water, and about packing.

Cost per Gallon of Water and Water Capacity Are the Best Value in Town  

The filter and purifier will both treat field water for pennies per gallon, now all you need to decide is whether or not you need viral protection. Both the Sawyer Water Filter and Sawyer Water Purifier can be “back washed” to extend their lives. To get the maximum water capacity use the clearest water possible.

No Pumping; No Chemicals; No Waiting; No Worries!
