ABSTRACT:
A high performance flatus gas filter assembly, and a body waste collection pouch with which it may be used, along with a method for making such an assembly, are disclosed. The assembly includes a filter pad having first and second layers of deodorizing filter media with an imperforate gas and odor barrier layer sandwiched therebetween for blocking the direct flow of gases between the opposing inner faces of the filter layers. An envelope of liquid and gas impermeable material defines a chamber for enclosing the pad. The envelope has walls with first and second openings communicating with central portions of the first and second filter layers, and defines a peripheral space about the pad to permit the outward flow of flatus gases from the peripheral edge surface of one of the filter layers inwardly into the peripheral edge surface of the other of the filter layers.
