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 sleeve (2). The latter filter segment forms a coaxial filter part of coaxial filter. 12 claims, 1 figure
