| abstract |
A disposable filter attachment for smoking articles, such as cigarettes, comprises first and second filter segments and an insertion tube at one end thereof for receiving and supporting a conventional filtered or unfiltered cigarette to be smoked. The first filter segment contains a carbonaceous material for removing gas phase components of the mainstream cigarette smoke. The total pressure drop across the filter attachment is very low, e.g., less than about 15 mm of water at 17.5 cc/sec air flow and preferably in the range of about 3 mm to about 12 mm of water at 17.5 cc/sec air flow. |
