Filed:

Apr 17, 2006

Appl. No.:

11/405264

Inventors:

Leonard Kott - North Massapequa NY, US
Samuel Miller - Trumbull CT, US

International Classification:

B01D 29/00

US Classification:

210338000, 210450000, 210501000, 210502100

Abstract:

A two-stage, tandem, replaceable filter cartridge assembly includes an outer filter cartridge having a cylindrical shape and defining an axial bore therein, and an inner filter cartridge, also having a cylindrical shape which is received within the axial bore of the outer filter cartridge. The inner filter cartridge may be collapsible so that it can be easily inserted inside the axial bore of the outer filter cartridge, and is expandable so that in normal applications, it rests up against the inner surface of the outer filter cartridge's core, if such is included, or filter medium. One or both of the filter media of the inner and outer cartridges may be formed from an antimicrobial material. In a second embodiment, each of the inner and outer filter cartridges has top and bottom end caps which respectively are structured to mate with one another to form seals therebetween to prevent or minimize the egress of water between the mating top and bottom end caps.
