The Folia Filter is a silver nanoparticle infused antimicrobial filter for water purification.
The Folia Filter is a paper-based, copper and silver nanoparticle infused antimicrobial water filter designed to purify water from tap, tube-wells, rivers, lakes, and ponds. The funnel design of the filter allows it to accommodate existing consumer water habits. The filter is designed, manufactured, and distributed by Folia Water.

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.
Technical Support
Safety precautions are provided by the manufacturer.
Replacement Components
N/A
Lifecycle
20 L and then needs to be replaced
Manufacturer Specified Performance Parameters
The filter was designed to reduce bacteria by 99.9999%, viruses by 99.9%, protozoans by 99.99%, and iron by 99.8%.
Vetted Performance Status
Live bacteria testing trials performed in-house, results of testing are unknown.
Safety
The filter should not be stored outdoors and always kept in its protective bag until used. For an unopened bag of filters, the shelf life is 12 months. The filter should not be used when the color has changed and/or the filter itself is torn/ripped.
Complementary Technical Systems
The filter requires a funnel to store the technology for use as well as two separate water storage containers, preferably 2 L water bottles
