Abstract

Filtrul de tigara, conform inventiei, este alcatuit dintr-o tija filtru poroasa cu un canal plasat longitudinal în acesta. Capatul canalului dinspre coloana de tutun a tigarii este închis de un perete impermeabil la fum care prezinta un orificiu cu o sectiune transversala mai mica decît cea a canalului pentru asigurarea comunicarii dintre coloana de tutun si canal. Tija poate fi înconjurata cu un material de acoperire permeabil la aer.
