Patent ID: 7215526

Claim:
An ion generator flooding an interior of a habitable space to be cleaned with cleansing ions without producing ozone, said interior to be cleaned of said habitable space at least partially provided by boundary walls defined by electrical ground, comprising: a) a high voltage power supply having opposite polarity ports and providing an ionizing potential, wherein one of said opposite polarity ports is adapted to be electrically coupled to the potential of said electrical ground and the other of said opposite polarity ports provides said ionizing potential; b) an ion emitter electrically connected to said one of said ports of opposite polarity of said power supply supplying said ionizing potential so that it floods said interior with cleansing ions when placed in said interior of said habitable space, which ions, attracted towards said electrical ground which serves as the counter electrode, efficiently remove dust, smoke or other particulate pollutants from substantially the entirety of said interior of said habitable space as the ions move towards said electrical ground and become captured on said boundary walls; and c) a safety circuit coupled to said high voltage power supply and operative in response to proximity of a human being in said habitable space near said ion emitter to turn off said power supply for a predetermined period of time to prevent electrical shock.
