Most filters capture dust and pollen but are unable to address chemical contaminants.

Colorfil filters capture dust, pollen, and chemical contaminants that other filters can't. They also change color from pink to yellow as they work so you'll never replace them too early.

Colorfil technology was developed with support from NASA the U.S. Army, and the National Science Foundation.
