Abstract

The invention relates to a ventilated filter cigarette, comprising a sleeved tobacco rod and a filter (7). Said filter consists of two filter sections (3, 4) and has ventilation elements. Ventilation elements are located in the area of the filter section (3) on the tobacco-rod side. In addition, the filter section (3) on the tobacco-rod side consists of a single filter segment, whereas the filter section (4) on the mouth side consists of a two-part filter segment, comprising a core (1) and a sleeve (2). The latter filter segment forms a coaxial filter part or coaxial filter.
