Folia Water

Folia Water's antimicrobial Folia Filter papers are the world's first water filters that cost pennies and not dollars. Each is packaged like a coffee filter and is a week of safe, germ-free water for a family for only 50¢, an affordable consumer product for families making $2-10/day. Folia is creating a new $1B consumer goods water filter category by selling through distributors to groceries and kiosks throughout developing countries as a mass-market staple at a 75-95% savings to bottled water.
