Abstract
The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.
