Design Specifications

The Folia Filter is a silver nanoparticle coated paper microfilm. As water passes through the filter, larger debris, dirt, and microorganisms are trapped by the small porous nature of the paper filter. Additionally, the water which passes through the filter carries silver cations that act to kill bacteria and other organisms by denaturing metabolic enzymes.
