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.
