An air-cleaning apparatus is mounted on a wall to collect particulates suspended in the air through electrical control. In the air-cleaning apparatus, a box is mounted on a wall to house therein a dust-collection unit and an air fan such as cross-flow fan for blowing air. The dust-collection unit collects the particulates suspended in the air by imparting a corona electric charge to these particulates, i.e., by rendering them an electrostatic charge. The box of the air-cleaning apparatus is provided with an air outlet in its lower section and also provided with a forward-protruding air duct in its upper section. The forward-protruding air duct is provided with an air inlet in its leading edge portion.
