Abstract
A filtering material for cigar or cigarette filter tips or holders, or tobacco pipes, comprises a support permeable to gases and impregnated with furfural slightly polymerized on the support. The support may be cotton or paper in thin layers or silica gel granules and is impregnated with furfural mixed with caustic potash or caustic soda and dried in a gentle air stream at 60 DEG C. to slightly polymerize it to form a furfural resin. After drying, the impregnated support is washed thrice in a solvent and once in water to eliminate the unpolymerized furfural, and again dried. The filtering material may be contained in a cartridge pierced at both ends to pass smoke.
