Abstract

A filter mouthpiece 12 is disclosed which delivers substantially constant levels of DPM which do not vary significantly from cigarette to cigarette. The mouthpiece comprises rod-end 14, middle 16 and mouth-end 18 filter portions in axial alignment with each other rendered generally impermeable over their peripheral surfaces. The middle portion includes a perforate tube 26, open at both ends. The filter mouthpiece may be ventilated. <IMAGE>
