Abstract: When the electrically driven fan (14) of a vacuum cleaner is driven, air containing dust is drawn into the cleaner main body (1) through a hose (7) connected to a hose socket (8) and is exhausted into the outside of the cleaner main body (1) through an exhaust port (1b) via first and second suction passageways (10, 13). Disposed outside the first suction passageway (10) is an ion generator (23), it being arranged that plus and minus ions generated in the ion generator (23) are fed to the air stream flowing in the first suction passageway (10). Since the plus and minus ions kill floating germs in the air stream, the exhaust can be purified.

Abstract: An air conditioning apparatus incorporates an ion generating device that generates positive and negative ions by applying an alternating-current voltage between electrodes. The generated positive and negative ions coexist in the air and, when they attach to the surfaces of airborne bacteria, they react chemically with each other and generate radical hydroxyl and hydrogen peroxide, which extract hydrogen atoms from the cells of the bacteria and thereby kill them. This sterilizing effect is combined with the temperature-conditioning, dehumidifying, humidifying, air-purifying, and other functions of the air conditioning apparatus to bring about a comfortable and healthful indoor environment.

Abstract: An ion generating device generates O2−(H2O)n (where n is a natural number) as negative ions and H+(H2O)m (where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide H2O2 or radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.
