<p>A suction air filtering and sterilizing method and system is disclosed, which mainly includes the following steps: Firstly, after activating the power source of a fan and sucking air by the fan, the air then is filtered out by a regular filter, dusts and particles seized by the filter are sterilized by an ultraviolet light tube. Next, the air enters into a plasma generator, wherein high-frequency and high-voltage electric energy ionizes the air into ozone plasma (or negative ion plasma), and now all of the bacteria and viruses contained in the air are killed; then the air mixed with the ozone plasma flows into a tank filled with water or other solvents using for adsorbing and filtering all the fine particles, and a ultraviolet light source is installed in the tank and is used to kill the bacteria adsorbed in the water or other solvents. The filtered air is then sucked out by the fan and enters into an air-filtering oil-eliminating drying system so as to eliminate the moisture in the air. As a result, the air free of dusts/particles, bacteria and water molecules may be obtained and be sent back to an indoor space.</p> |
