ABSTRACT:
An exhaust gas filter cartridge which is suitable for use in a muffler such as to form an exhaust gas filtering system is disclosed. The filter cartridge preferably includes a first porous longitudinal wall and a second porous longitudinal wall, both porous longitudinal walls having openings which allow for a sufficient gas flow through the filter cartridge. An absorbent material, preferably in pellet form, is housed substantially in-between the first porous longitudinal wall and the second porous longitudinal wall of the filter cartridge. The filter cartridge is preferably disposable. A guard casing may be used in conjunction with the filter cartridge to provide an exhaust gas filtering system. The guard casing preferably has two end closure structures. A gas inlet end structure is preferably associated with one end closure structure and a gas outlet end structure may be associated with the other end closure structure of the guard casing.
