Flow rate information for Point Zero Two purifiers.
Sawyer's Guarantee: The Sawyer Company is confident in their million gallon claim because you can continually clean the filter by backwashing it with clean water. So there really is no end to its useful life. That is why they can GUARANTEE THE FILTER FOR LIFE as long as you follow the simple care and use instructions.
Follow the helpful hints included in the directions for use. Backwashing is not required often unless you are filtering very turbid water. Backwashing only takes a few seconds. If you are accustomed to a ceramic filter, the leaning ratio is approximately 20:1. In other words, by the time you first need to clean your hollow-fiber filter you would have needed to clean a ceramic filter 20 times. NO REPLACEMENT FILTERS OR CARTRIDGES ARE NECESSARY.
The Sawyer Water Filters feature a 0.02 Micron Absolute Hollow Fiber Membrane, which uses medical technology developed from kidney dialysis. When the water is drawn through the filter, it flows through the side walls of the Hollow Fiber tubes. Viruses, sediment, bacteria, protozoa, cysts, and other contaminants are filtered out exceeding all applicable EPA recommendations.
NO CHEMICALS, NO WAITING, NO PUMPING, NO WORRIES!
