Abstract:
1. A window screen apparatus that utilizes electrostatic properties to purify the air passing through or in the vicinity of the apparatus comprising: a. a window screen frame designed to fit and latch into the window frame for which the apparatus is designed to be mounted; and b. a pair of electrically-conductive tracks that run the perimeter of the apparatus frame and are electrically insulated from each other and the apparatus frame, with one track being designated the negative potential track and the other track being designated the positive potential track; and c. a wire mesh screen, consisting of interwoven or cross-hatched wires, mounted to the window screen frame; and d. a power supply unit electrically connected to the tracks that generates high-voltage, low-amperage DC electric pulses; and e. a cleaning mechanism mounted to the window screen frame that cleans the wire mesh screen.
