An automatic air scenting system that introduces a variety of pre-selectable scents into the heating/air-conditioning duct of a motor vehicle or habitable structure comprising a perforated housing, an electric fan for drawing air through the perforated housing, a container of compressed fiber blocks soaked in a scented oil based liquid positioned within the perforated housing, and a hose connecting the housing to the duct of the heating/air conditioning system whereby the fan forces the accumulated scent through the hose into the duct. Automatic functioning is obtained by connecting the fan power lines to the on/off switch and thermostat wiring of the heating/air-conditioning system.

[ What is claimed:] [1.] An apparatus for introducing a pre-selectable plurality of scents obtained from a plurality of scented oil based liquids into the duct of an existing electrically energizable heating/air conditioning system of a motor vehicle or habitable structure electrically connected to a power supply wherein said heating/air conditioning system is controlled by an on/off switch or thermostat comprising:a housing element comprising a lid having a plurality of air holes and a top and a bottom, a container, and a fan fixedly engaged to said bottom of said lid wherein said fan is electrically energizable and electrically connected to said on/off switch or thermostat;a canister element removably positioned within the housing element comprising a cage and a plurality of blocks wherein the blocks are impregnated with a scented oil based liquid; anda connecting element removably engaged to said housing element and said duct; wherein said fan upon being electrically energized causes air to be drawn through the plurality of apertures in said lid so that the air passes over the blocks and is forced through the connecting element into the duct. [5.] A method of introducing a pre-selectable plurality of scents obtained from a plurality of scented oil based liquids into the air duct of an existing electrically energizable heating/air conditioning system of a motor vehicle or habitable structure controlled by an on/off switch or thermostat comprising:selecting the scented oil based liquid with the desired scent;pouring the selected scented oil based liquid into a vessel;placing blocks into the vessel containing the scented oil based liquid;soaking the blocks in the vessel containing the scented oil based liquid;removing the blocks and placing them in a cage;placing the cage inside a container;removably engaging said lid to said container by means of a plurality of fasteners;connecting a plurality of wires to the fan and to the on/off switch or thermostat of the heating/air conditioning system so that the fan will be electrically energized when the on/off switch or the thermostat provides power to the heating/air conditioning system;creating an aperture in the duct of the existing heating air conditioning system for receiving a connector fitting; andconnecting the housing element to the aperture by means of a connecting element comprising a hose and a plurality of connector fittings.
