This Electronic Air Cleaner is a two-stage electrostatic precipitator. The air cleaner is designed to remove airborne particulates, including dust, dirt, smoke, pollen, virus, spores, bacteria, and mold from indoor air. Air movement through the unit is provided by the heating, air conditioning or ventilating system blower. As dirty air enters the air cleaner, the air passes through Metal Mesh Pre-filters. The Prefilters prevent lint, pet hair and other large particulates from entering the air cleaner. It is important that these filters be in place to prevent excessive dirt loading of the air cleaner Ionizing-Collecting Cells. These filters extend the time interval between scheduled maintenance of the air cleaner, which allows the Ionizing-Collecting Cells to provide clean air for a longer period between washings. The pre-filtered air then passes through a two-stage Electronic Air Cleaner. In the first stage, all airborne particulate, even submicron size, are electronically charged (positive) as they pass through the ionizer section. The ionizer field is a result of a corona discharge emanating from the fine, tightly strung wires suspended between two adjacent flat plates. In the second stage, the charged particulate passes through an intense electrical field established between alternately charged and grounded parallel collector plates. Here, the charged (positive) particulate is attracted to the ground (negative) plates and removed from the air stream.
