Abstract

A filter for a smoking article comprising a flow restrictor (34) configured to cause an increase in velocity of smoke drawn through the filter; and at least one guide surface (36) configured to cause swirling motion of the increased velocity smoke, such that constituents of the smoke impact and are captured by the filter.
