Abstract

This invention provides an air cleaner, which has antimicrobial activity during both the operation of the device and the stop of the device, does not deteriorate resins, is safe to the human body and is inexpensive, and an air conditioner or a refrigerator using the air cleaner. The air cleaner comprises a filter member (2) with at least silver formed on its surface and a light source (3), which can apply light with a wavelength of more than 400 nm and not more than 520 nm, provided on the surface of the filter member (2). According to the above constitution, in a period in which no light is applied during the stop of the operation of the device, the antimicrobial activity possessed by silver can be exhibited. On the other hand, in a period in which light is applied during the operation of the device, the antimicrobial activity of silver can be enhanced by the light. This can realize the development of a higher level of antimicrobial activity. Further, the limitation of the wavelength of the light can provide an air cleaner which is safe to the human body and is inexpensive without deterioration in resins.
