Cigaretový filtr obsahuje mikrovlákna (21), pricemž též obsahuje od 0,5 do 10 % hmotnostních polymerních nanovláken (22), která jsou usporádána mezi mikrovlákny (21). Pri zpusobu výroby cigaretového filtru obsahujících mikrovlákna (21) se k povrchu útvaru urceného k výrobe cigaretového filtru (2) tvoreného alespon z 90 % hmotnostních mikrovlákny (21) privedou nanovlákna (22) nebo útržky (23) plošné nanovlákenné textilie a uloží se na povrchu a/nebo v objemu útvaru v množství od 0,5 do 10 % hmotnostních. The invention relates to the cigarette filter containing the microfibres, which contains from 0.5 to 10% by weight of polymeric nanofibres, that are arranged among the microfibres. At manufacturing of cigarette filter containing the microfibres, the nanofibres or shreds of surface nanofibrous textile are brought to the surface of a configuration designated for production of the cigarette filter formed at least of 90% by weight of microfibres, and they are deposited onto the surface and/or into the volume of the configuration in a quantity from 0.5 to 10% b weight.
