After years of working on clean water projects across the globe, founder Bob Ashley saw a troubling pattern: existing filters worked well, but they were too costly for the families that needed them most.

Determined to change that, he spent two years designing and testing what would become the VF100—a lightweight, portable water filter made from the same high-quality membranes used in top-tier systems, but at a fraction of the cost.

We provide a simple, effective filter that attaches to any standard bucket. But to make this filter affordable for a family earning $2 a day or less, we don't use assembly lines. Our filters are assembled by hand, by volunteers. By you.
