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 is amazing. They offer virtually no resistance until they start to near the end of their cycle. Just Drink™. No sucking your brains out, no sucking for just a few drops of water per stroke. These Sawyer® Filters can handle 40 PSI, which means you can 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 can squeeze the bag (okay – you can sit on the bag also) and get large quantities of water incredibly fast. 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 Sawyer® Water Filter yields over 500 gallons of water (the filter now has a LIFETIME WARRANTY) when used with a reasonably clear source of water for less than 7 cents per gallon. The Sawyer® Water Purifier can yield over 3,000 gallons (the purifier now has a LIFETIME WARRANTY as well) from the same water source. The filter and purifier will both treat field water for pennies per gallon (lower cost/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!
