• b) at least one first filter membrane constituting at least a portion of said at least one wall of said cartridge housing;
• c) a cartridge input port with said fluid inlet of said filter housing to direct said fluid to said removable cartridge housing;
• and,
• d) at least one movable inner filter, removably arranged within said interior of said removable cartridge housing and positioned to receive said fluid coming into said cartridge input port and be moved by said fluid, wherein said fluid passes said at least one movable inner filter reaching said filter membrane on said removable cartridge housing;
• wherein said at least one movable inner filter comprising a plurality of freely movable surfaces selected from a group consisting of bands, ribbons, tapes, floccules, strings, sheets, crumpled sheets and disks, said freely movable surfaces arranged to brush against said at least one wall thereby operating to remove and retain said impurities from said at least one wall.
