Encapsulated lenticular filter cartridge

A method of manufacturing a fluid filtration device comprising the steps of:

• a) providing a capsule housing including an upper housing portion and a lower housing portion, said upper housing portion having an upper circumferential mating surface, said lower housing portion having a lower circumferential mating surface and an annular retention ring
• b) providing a filter assembly including an elongated mounting post having an upper end portion including a compression flange and a lower end portion including an engagement fitting dimensioned and configured to engage the annular retention ring formed within the lower housing portion, said annular retention ring projecting radially to engage said engagement fitting and a plurality of filtration cells supported on said mounting post in axially spaced apart relationship;
• and
• c) engaging said engagement fitting of said mounting post in said annular retention ring of said lower housing portion so as to axially compress said filtration cells relative to said mounting post to effect a positive seal between said filtration cells and said lower housing portion.

A fluid filtration device comprising:

• a) a capsule housing including an upper housing portion defining a fluid inlet and a lower housing portion defining a fluid outlet;
• b) a filter assembly including an elongated mounting post and at least one filtration cell supported on said mounting post, said mounting post having an integral engagement fitting formed at a lower end portion thereof;
• and
• c) a retention structure integrally formed in said lower housing portion adjacent said fluid outlet for receiving and retaining said engagement fitting of said mounting post, said retention structure including a annular retention ring projecting radially inwardly to engage said engagement fitting, said at least one filtration cell adapted to be axially compressed relative to said mounting post when said engagement fitting is engaged with said annular retention ring.
