Abstract

L'invention concerne un article à fumer comprenant un système filtrant comprenant une première section de filtre et une seconde section de filtre, la seconde section de filtre étant située en aval de la première section de filtre, et un système de ventilation configuré pour fournir un niveau de ventilation pouvant être réglé par l'utilisateur dans la première section de filtre. Une résistance à l'écoulement gazeux sur la longueur de la seconde section de filtre est inférieure à une résistance à l'écoulement gazeux sur la longueur de la première section de filtre, et la résistance à l'écoulement gazeux sur la longueur du système filtrant reste sensiblement constante lorsque le niveau de ventilation varie.
