Folia Water has created the world's first consumer goods water filter: Folia Filters™. Our global vision is to reach the 1.8 billion people who consume microbiologically contaminated drinking water as well as the 2 billion people who pay the poverty penalty: overpaying in time, energy, or money to obtain safe drinking water. Lack of clean water is catastrophic for public health: diarrheal illnesses kill more than 500,000 children a year. Folia Filters™ kill waterborne pathogens at a price that is affordable to even those who make $1-10/day. Our filter papers are designed to fit into either a regular plastic funnel or our Keystone Funnel™. The Keystone Funnel™ allows users to walk away and leave a 2 liter bottle of dirty water to drain through a Folia Filter into any household water container including a soda bottle or jerry can. The Keystone Funnel is designed to be simple to use, effective, and culturally appropriate, minimizing customers' setup time and not requiring them to buy a special water bottle. We aim to promote human welfare through innovation to reduce waterborne disease, one Folia Filter™ at a time.
