Marketing InformationElectronic air cleaners work by placing a charge on airborne particles utilizing the principle of 2 stage electrostatic precipitation and then collecting them like a magnet. They remove small, invisible particles that bypass standard air filters. Air is drawn by the ventilating system and blower through a washable metal mesh pre filter, which traps large dust particles. The remaining particles (some as small as 0.01 micron) pass into a strong electrical field (ionizing section) where the particulate receives an electrical charge. The charged particles are then trapped into a negatively charged series of equally spaced parallel plates. The air, now cleaned of up to 95% of its impurities, is returned to the home.
