Abstract
Air quality control systems for rooms or other enclosed spaces relying on generators which supply charges to particles present in the air thereby purifying or otherwise controlling the condition of the air. A source of high voltage is connected to radiating surfaces of various configurations carrying electrostatic charges. A fan or other air circulating device including natural air movement insures adequate contact of the air with the charges generated to thereby achieve the desired quality control. Operating mechanisms provided in the system include voltage varying circuitry to permit adjustment of the generating intensity. A sensor is provided to detect variations in conditions thereby permitting automatic voltage variations. A remote control station is comtemplated where independent environments may be involved and where separate control of these environments is desired. Switching of the system polarity enable production of positive or negative electrostatic charges depending on the atmospheric conditions encountered.
