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.
