Abstract: A self-acting device for filtering the smoke commonly associated with cigarettes and cigars includes an ashtray which supports a shroud for confining smoke. The shroud in turn supports a motorized fan which creates a flow of air to carry the smoke. In close proximity to the fan and also supported by the shroud is a detector which acts to sequentially sense the smoke and activate the fan motor. A portion of the detector also serves to separate a certain amount of the smoke from the air. Smoke which remains is further drawn upwards by the suction forces created by the fan through a filter before the filtered air is ultimately propelled into the immediately surrounding environment.

Abstract: A device for filtering the smoke commonly associated with cigarettes and cigars includes an ashtray which supports a shroud for confining the smoke. The shroud in turn supports a motorized fan which creates a flow of air to carry the smoke through a filter. A motor for driving the fan is removed from the flow of air to prevent contamination of the motor by the smoke fumes. An elongated filter and a cylindrical filter are both provided with cartridge configurations to facilitate the removal and replacement of the filters. An absorbent material is impregnated with a perfume to enhance the fragrance of the flow of air through the device.
