Abstract
Abstract An air purifying and deodorizing device for an automobile comprising a housing positioned on the rear window deck of the automobile and having air intake and air discharge openings. An electronic filtering device is mounted at the air intake opening for removing air-borne particles from the air being taken into the device. A ring-shaped filter device is positioned in the housing for further filtering the air as it passes therethrough. A deodorant cup is positioned within the ring-shaped filter and deodorizes the air as the air passes through the device. An electric fan means is positioned below the rear deck and is adapted to draw the air through the device and to discharge the same through the discharge opening. A directional vent is provided at the discharge opening for directing the discharged air onto the rear window to de-fog the same. An optional purifying and deodorizing device may also be employed which is adapted to supply outside air into the interior of the vehicle and to purify and deodorize the same.
