Abstract

The invention relates to a filter cigarette comprising a biodegradable filter and a tobacco strand surrounded by cigarette paper, a non-woven air-laid cellulose filter with a normal retention capacity and a filter ventilation area extending in a peripheral direction. The inventive filter cigarette has the following combination of features: the filter has a condensate retention capacity of 40-60 %; the non-woven cellulose is non-crimped, the nicotine/tobacco strand condensate yield ratio lies between 0,6 and 0,9 (nicotine *10/condensate), the apparent density of the tobacco mixture of the tobacco strand ranges from 200 to 250mg/ml, the tobacco strand drag is between 45 and 65 mmwWS when measured in an enclosed form, air permeability of the cigarette paper is 20-50 CORESTA units and the filter ventilation degree is 15-50 %.
