Abstract
A cigarette filter assembly has a filter plug and an open mixing chamber arranged between the filter plug and the distal end of the filter assembly. Perforations are formed in the filter assembly wrapper to communicate between the mixing chamber and outside air, for the purpose of drawing in diluting air to mix with the filtered smoke in the mixing chamber. The filter assembly is constructed to pass smoke and diluting air substantially unimpeded from the mixing chamber to the distal end.
