The Sawyer water filtration systems use technology adapted from kidney dialysis filters. The Sawyer Hollow Fiber Membrane Filters are composed of tiny “U” shaped micro tubes that allow water to enter into their core through tiny micro pores on the side walls of the tubes.  The pores on our filters and purifiers are so small that no bacteria such as E. Coli, cholera, or typhoid can pass through.  The 0.1 micron absolute filter and 0.02 micron absolute purifier not only exceed EPA pathogen removal rate standards, these systems will also out perform and outlast most other personal filters on the market.
