Colorfil does more
Colorfil filters capture not only dust and pollen, but also odors and chemical contaminants that other filters can't. They change color from pink to yellow as they work so you'll know exactly when to change them.
Built for astronauts, now for you
Colorfil air filters were originally built for astronauts with funding from NASA, NSF, and US Army to meet their rigorous demands. Now Colorfil brings clean air to your home, your pets, and your family, wherever you may be.
