Aprilaire electronic air cleaners apply the same ionization technology to clean and improve indoor air quality. Air enters the system and passes through a control electrode with ionizing wires, producing a strong electric field. The electric field charges pollutant particles, forcing them to clump and collect at a grounded microfiber in media.Aprilaire carries an air filter for every need. Each of their air filters is effective against airborne particles like dust, pollen, and dander. They also effectively remove bacteria, viruses, mold, and dust mites. For example, the Allergy and Asthma Filter MERV 16 is 99% effective against airborne allergy and asthma triggers.
