The air you breathe contains many irritants such as pollen, dust, bacteria, mold spores, pet dander and smoke. Most of these particles are smaller than one micron. Your electrostatic air filter is an effective and efficient way to remove these particles from your air. Electrostatic Air Filters clean the air by using static electricty, a safe, naturally occurring phenomenon. An electrostatic charge is generated by air flowing through a maze of static prone fibers. Airborne particles are attracted and held by a static charge, until released by washing.
