Abstract

An air cleaning apparatus includes: a collection filter for collecting dust; a first ultraviolet light emitter for irradiating the collection filter with ultraviolet light having a first wavelength; and a photocatalyst supporting filter which supports a photocatalyst exhibiting photocatalytic activity by the ultraviolet light having the first wavelength and collects the dust. The collection filter transmits the ultraviolet light having the first wavelength, and the ultraviolet light having the first wavelength passing through the collection filter is irradiated to the photocatalyst supporting filter.
