Abstract
This invention provides a cigarette filter comprising a filtering core (2, 4), a smoke-impermeable wrapper (16) in surrounding engagement with the core, tipping material (8) in surrounding engagement with the impermeable wrapper, at least one passage (14) defined between the impermeable wrapper and core and open at an end of the filter, and at least one further passage (16) defined between the impermeable wrapper and tipping material and open at an end of the filter, the tipping material providing, when the filter is drawn on in use, for the ingress of external air laterally therethrough into said further passage. The tipping material may be a tipping overwrap incorporating the filter in a filtered cigarette. The impermeable wrapper may be profiled to provide the passages, which may extend fully or only partially the length of the core. <IMAGE>
