Abstract (en)
[origin: US2008251091A1] A tobacco smoking filter is disclosed, with adjunets on the surface in the form of fibres filaments or films and whereby the drawing resistance of the tobacco smoking filter and the mass of the adjuncts in the tobacco smoking filter meet the following equation (I) M<SUB>ad</SUB>/Deltap>1 mg/daPA (I), where Deltap is the drawing resistance [daPA], applied as a value calculated with a 7.8 mm filter diameter and M<SUB>ad </SUB>[mg] is the mass of the adjuncts. The tobacco smoking filter comprises channel structures and the filer material is provided as a planar material. Said tobacco smoking filter has a low draw resistance on smoking with a particularly good filtration effect and is relatively simple to produce.
