Abstract

A tobacco smoke filter element comprises a wrapped core (4). The wrapper (2) is longitudinally corrugated to provide, externally thereof, passages (6) extending longitudinally of the filter. The wrapper also has a circumferential groove (8) into which the said passages open. For use the filter element can be provided with an air-permeable wrap, which may be a ventilating tipping overwrap incorporating the element in a filter cigarette such an overwrap suitably has ventilating perforations opening directly into the circumferential groove.
