An air deflector can be mounted on an air register. The deflector has a sloping rear wall and a pair of side walls. The two side walls have opposed holes which support a perforated, finned roller rotatable about a horizontal axis. The roller has six horizontally curved fins spaced equally apart with perforations above them. The rear wall defines with the roller a flow path extending through the deflector sets the roller in rotation and is thereby projected out of the top of the deflector at an increased velocity and over a greater distance into the room. A solid circular stick of deodorizer can be internally located within the finned roller.
