ABSTRACT:
A filter for tobacco smoke comprises a porous substrate (other than tobacco) having a deposit thereon of particles of a water-insoluble hydrophobic moisture-laden substance, the major ingredient of the substance being water, which is activated by the smoke of burning tobacco to release the moisture. The filter may be in the form of a cartridge for insertion in a cigarette or cigar holder or as a filter tip made integral with a body of divided tobacco.
