The CFS ES filter uses the natural phenomenon of static electricity to extract airborne contaminants. Just like walking across certain carpets creates a "shock" the woven polypropylene media generates an electrostatic charge as air passes over it. Airborn pollutants such as dust, pollen, mold, bacteria and lint particles contact the polypropylene fibers are forcibly held in place by the electrostatic charge.
