Filter unit for reducing temperature of heating non-burning cigarette smoke

The invention relates to the technical field of tobacco products, in particular to a filter unit for reducing the temperature of a heating non-burning cigarette smoke. The filter unit is a cylinder ofa longitudinal multi-channel structure which is made of a first non-woven material or a non-woven composite material, the filter unit is obtained by embossing, folding and gathering of the first non-woven material or the non-woven composite material, or the filter unit is obtained by cutting the first non-woven material or the non-woven composite material into a strip with a width of 2-5 mm and then gathering; the surfaces of both the first non-woven material and the non-woven fabric material are provided with hydrophilic antibacterial layers. The invention discloses the filter unit for reducing the temperature of the heating non-burning cigarette smoke, which can effectively reduce the temperature of the heating non-burning cigarette smoke, so that the aerosol temperature reaching an oral cavity is below 70 DEG
