Abstract
An indoor air pollutant destruction apparatus destroys pollutants by a corona discharge that is generated by a rapidly oscillating electric field. Free electrons generated by the corona discharge produces ozone (O.sub.3), which effectively destroys volatile organic compounds (VOCs) and biological forms such as bacteria, fungi, viruses and spores. Fine particulate materials such as smoke and dust are charged by the corona discharge, and when they pass through the rapidly oscillating electric field, they coagulate to form larger particles which are then filtered out.
