Abstract
A humidification and air cleaning apparatus is provided, in which a wave having a predetermined cycle is formed on a plurality of blades of a blower fan, such that operating noise caused by a flow of discharged air may be minimized, and a wave is formed at a trailing edge, such that a phase difference may be formed for air to be separated, and air flow noise of the discharged air may be reduced.
