ABSTRACT:
A filter assembly for use with a cigarette includes a porous filter element with a longitudinally extending hollow tube extending from each end thereof, the filter element being circumscribed by a non-porous wrapping material. The filter assembly further includes a chamber axially aligned with the porous filter element and disposed between the filter element and a tobacco column. The chamber is provided with means to direct ventilating air into the hollow tube and means to direct smoke from the tobacco column into the filter element without mixing with the ventilating air. When in use, the smoke and ventilating air exit in separate streams, the smoke exiting in streams which surround the ventilating air exiting the filter through the hollow tube.
