An air cleaning apparatus and comprising a housing that has at least one opening thereon, at least one rotation-driving device therein and at least one ultraviolet irradiator disposed in a suitable position therein. The rotation-driving device connects to a blade to drive such blade to rotate. A layer of photo catalyst is coated on the surface of the blade. The ultraviolet irradiator irradiates the photo catalytic layer on the blade to activate the photo catalyst to clean the air. The cleaned air then flows through the opening of the housing under the rotation of the blade to clean the air of an indoor and local space rapidly and produce an active air cleaning effect.
