Filters for Cigarettes, Pipes, and Cigars and Related Products

Abstract

A filter media containing continuous nanofiber or submicron fiber having low air resistance that that can be incorporated into cigarettes, cigarette attachments, pipes, and cigars. The media may formed in circular or cylindrical shapes and is comprised of thin, flexible fabric forms that can be cut and fit into the body or cavity of cigarettes, cigarette attachments, pipes, cigars, and other tobacco related products and incorporates a nanofiber or submicron fiber coating creating an interfiber spacing between 1.0 to 2.0 μm, preferably between 1.2 and 1.5 μm.

What is claimed is: 
     
         1 . A filter for inhalable tobacco products comprising at least one nanofiber coated fabric. 
     
     
         2 . The filter of  claim 1  wherein said filter is either circular or cylindrical in shape. 
     
     
         3 . The filter of  claim 2  wherein said filter has an interfiber spacing between 1.0 μm to 2.0 μm. 
     
     
         4 . The filter of  claim 3  wherein said interfiber spacing is between 1.2 μm and 1.5 μm. 
     
     
         5 . The filter of  claim 3  wherein said inhalable tobacco products consist of one of the group of cigarettes, cigars, and pipes. 
     
     
         6 . The filter of  claim 5  wherein said filter is able to capture at least 50% of the tar passing therethrough and allowing over 60% of nicotine to pass through. 
     
     
         7 . The filter of  claim 6  wherein said filter captures 50% to 100% of the tar passing therethrough. 
     
     
         9 . A circular or cylindrical shape filter for cigarettes containing at least one nanofiber coated fabric. 
     
     
         10 . The filter of claim  8  wherein the cylindrical shape filter is prepared by rolling up one or more sheets of nanofiber coated fabrics. 
     
     
         11 . The filter of  claim 9  wherein the coated fabric includes sub-micron fibers. 
     
     
         12 . The filter of  claim 9  wherein said nanofibers are continuous and have diameter ranges from 2 nm to 5 μm, preferably in the range of 10 nm to 800 nm. 
     
     
         13 . The filter of  claim 11  wherein said nanofiber coating creates interfiber spacing between 1.0 μm to 2.0 μm, preferably between 1.2 μm and 1.5 μm. 
     
     
         14 . The filter of  claim 13  wherein said filter captures between 50% to 100% of the tar passing therethrough and allows over 60% of nicotine to pass through. 
     
     
         15 . The filter of  claim 11  wherein said submicron fiber coating creates interfiber spacing between 1.0 to 2.0 μm, preferably between 1.2 and 1.5 μm. 
     
     
         16 . The filter of  claim 15  wherein said filter captures between 50% to 100% of the tar passing therethrough and allows over 60% of nicotine to pass through. 
     
     
         18 . A cylindrical shape filter for pipes containing one or multiple nanofiber coated fabrics having low air resistance and interfiber spacing between 1.0 to 2.0 μm. 
     
     
         19 . The filter of  claim 18  wherein said the cylindrical shape filter is prepared by rolling up one or more sheets of nanofiber coated fabrics. 
     
     
         20 . The filter of  claim 19  wherein said coated fabrics include submicron fibers. 
     
     
         21 . A filter comprising at least one nanofiber coated fabric having interfiber spacing between 1.0 μm and 2.0 μm and a ventilation system whereby said ventilation system and filter may be used to remove the smoke and associated tar components of smoke in a room.
