<P>PROBLEM TO BE SOLVED: To provide an air cleaning device using both an antibody filter and an ozone generator, which can be downsized. <P>SOLUTION: The surface temperature of the antibody filter is estimated by using a solar radiation sensor 23 or the like. When the estimated surface temperature exceeds, for instance, 50°C set as a threshold temperature, an ozonizer 12 is turned on, while when it does not, the ozonizer 12 is kept off. Consequently, when the surface temperature is low, the antibody filter 15 inactivates viruses, and when the surface temperature is high, the ozonizer 12 works to deodorize and sterilize with ozone, as the antibody filter 15 is denatured and therefore is less effective in inactivating viruses under the condition. <P>COPYRIGHT: (C)2013,JPO&INPIT |
