Abstract: A method of manufacturing a cartridge for a fluid treatment system, wherein the cartridge includes a housing defining at least one chamber for a fluid treatment medium, includes providing a cartridge housing part including at least one wall defining at least one opening closable by a filter element. The filter element includes a porous body for at least mechanically filtering fluid flowing into the filter element through at least one first surface area of the filter element, through the porous body and out through at least one second surface area of the filter element. The filter element includes a rim, covering at least a peripheral face of the porous body so as to frame the first and second surface areas. The filter element is combined with the cartridge housing part so as to close at least one of the at least one openings by bonding the rim to the cartridge housing part.

Abstract: A method of manufacturing a cartridge (104; 204; 304; 404; 504; 604; 704; 804) for a fluid treatment system (101; 401), wherein the cartridge (104; 204; 304; 404; 504; 604; 704; 804) includes a housing defining at least one chamber for a fluid treatment medium, includes providing a cartridge housing part (212; 312; 512; 612; 712; 812) including at least one wall (217; 313; 517; 613; 713; 813) defining at least one opening (218; 318; 518; 618; 718; 818) closable by a filter element (219; 319; 519; 619; 719; 819). The filter element (219; 319; 519; 619; 719; 819) is provided.
