Abstract
A smoke filter (3) for a smoking article (e.g. a cigarette) comprises a filter plug (3) having ducts (5) extending part way along the plug from the mouth end thereof, and opening in register with inlets (9) through wrapping means (7) around the plug (4) to provide segregated peripheral venting of the filter. Further apertures (10) in the wrapping means (7) communicate directly with the filter plug away from the ducts (5), to permit ambient air to enter the filter plug to mix with and dilute the smoke being filtered within the plug. In one embodiment of the invention mixing of ambient air with smoke being filtered within the plug is facilitated by provision of a circumferentially extending channel (13) which is in register with said further apertures. <IMAGE>
