A liquid filter assembly comprising a filter subassembly is inserted within an elongated tubular filter body, enclosed by a pair of end caps. The filter subassembly includes a plurality of filtration discs placed onto a tubular core and inner support member. A disc aperture is provided concentrically through each filtration disc. An outer filter support member and a central filter support member support each filtration disc. The outer filter support member engages with an interior of the elongated body and an end wall engages with the disc perimeter. The central filter support member engages with an exterior of the inner support member and an end wall engages with the peripheral edge about the filtration disc aperture. Fluid passes through the first end cap orifice, continuing through the inner support member, transferring flow through the filtration discs, returning through the inner support member, and exiting the opposite end cap orifice. |

1. A method of assembling and using a liquid filter cartridge device, the method comprising steps of:
assembling said liquid filter cartridge device in accordance with the following steps:
obtaining an elongated tubular filter body, said elongated tubular filter body being defined by a first body edge, a second body edge, an exterior surface spanning between said first body edge and said second body edge, and an interior surface spanning between said first body edge and said second body edge, said inner surface defining an interior void passing said elongated tubular filter body;obtaining a tubular core adapted to provide inner support, said tubular core spanning between a tubular core first filter orifice and a tubular core second filter orifice;obtaining at least one filtration disc defined by an outer peripheral edge and having a centrally located filtration disc assembly aperture, wherein said outer peripheral edge of each of said at least one filtration disc is of a size and shape of said interior void defined by said inner surface of said elongated tubular filter body and said centrally located filtration disc assembly aperture is of a size and shape defined by a cross section of an exterior surface of said tubular core;obtaining at least two outer filter support members, each outer filter support member having a tubular shape comprising an outer circumferential shape for placement and retention within said interior void of said elongated tubular filter body and an inner circumferential shape sized to engage with said respective filtration disc at a location proximate said filtration disc outer peripheral edge;obtaining at least two central filter support members, each central filter support member having a tubular shape comprising an inner circumferential shape for placement onto an exterior of said tubular core and an outer circumferential shape sized to engage with said respective filtration disc at a location proximate said centrally located filtration disc assembly aperture, wherein the at least two central filter support members and the at least two outer filter support members are independent of one another;sliding a first of said at least two outer filter support members along said elongated tubular filter body interior surface of said elongated tubular filter body into a desired position;sliding a first of said at least two central filter support members upon said tubular core into a desired position;sliding said tubular core through said centrally located filtration disc assembly aperture of one of said at least one filtration disc, seating a respective central portion of a first surface of said filtration disc circumscribing a region proximate an edge of said centrally located filtration disc assembly aperture against a first end surface of said first of said at least two central filter support members and seating a respective distal portion of said first surface of said filtration disc circumscribing a region proximate a distal peripheral edge of said filtration disc against a first end surface of said first of said at least two outer filter support members;sliding a second of said at least two central filter support members along said tubular core exterior surface, seating a respective edge of said second of said at least two central filter support members against a central portion of a respective second, opposite surface of said respective filtration disc circumscribing a region proximate said edge of said centrally located filtration disc assembly aperture;sliding a second of said at least two outer filter support members along said elongated tubular filter body interior surface seating a respective edge of said second of said at least two outer filter support members against a distal region of said respective second, opposite surface of said respective filtration disc circumscribing a region proximate said distal peripheral edge of said respective filtration disc;applying sufficient force from each of said at least two outer filter support members and each of said at least two central filter support members against each of said at least one filtration disc to maintain each of said at least one filtration disc in a useable, generally planar configuration; using said liquid filter cartridge device to filter a fluid as follows: supplying a fluid through said tubular core first filter orifice into said tubular core, transferring said fluid from said tubular core to a filtration flow area, wherein said filtration flow area is defined by a volumetric space between said elongated tubular filter body interior surface and said tubular core exterior surface; passing said flowing fluid through each of said at least one filtration disc, wherein each of said at least one filtration disc removes contaminants from said flowing fluid, returning said filtered fluid from said filtration flow area to said tubular core, and discharging said filtered fluid through said tubular core second filter orifice. |
