Abstract: An air freshener includes container which carries a cartridge having a plurality of sections, each of which is filled with a porous material impregnated with a differently scented substance. At least the front wall of the container has an aperture of generally the same shape and size as the cartridge sections. The cartridge may be rotated within the container to selectively bring one of its sections into alignment with the aperture, in order to expose a scented substance in one of the sections to the ambient air contained within a room, causing evaporation of the scented substance and freshening of the room's air. The back wall of the container may also be provided with an aperture, which is in general axial alignment with the front wall aperture, and tape or the like surrounding the aperture, so that the air freshener may be mounted over a vent or the like. In this manner, the fragrant scent will be spread into a room by force rather than by convection.
