Abstract: A filter housing assembly for fluid filtration which may be attached to, and removed from, a filter base by a push-actuated release. The filter housing assembly has a top portion with an ingress port and egress port extending therefrom, and a protrusion extending from the filter housing longitudinally axial center. The ingress and egress port are formed in an hourglass shape. A filter key having a base with a groove for mating with said projection, at least one finger extending from said base, and an electronic circuit component housing attached thereto for receiving a printed circuit board, is connected to the filter housing top portion by mating said top portion protrusion with the filter key groove. Both of said ingress and egress port have at least one cavity for the passage of fluid therethrough, where each cavity is exposed in a direction facing away from the printed circuit board.

Abstract: A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.

Abstract: A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a filter key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter housing assembly may be attached to, and removed from, a filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: A single sheet water filter media for gravity filtration applications that improves flow performance over the product life while maintaining sufficient metal reduction, wherein at least two distinct density gradients of the single sheet form a physical barrier for capturing colloidal and insoluble contaminants, retaining the colloidal and insoluble contaminants until the contaminants become soluble in the fluid, and being removed by the single sheet filter media. The single sheet filter overcomes the difficulties of dual- and multi-layer filters attributable to slower flow rate realized well before the rated lifetime of the product. The two distinct density gradients of the single sheet filter media are created by exerting a force on a liquid slurry, such force resulting in the separation of higher powder loading and fibers that compose the top and bottom density gradients, respectfully.

Abstract: A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism and latch blocking structure in the manifold secures the filter cartridge with a manifold sump when the filter cartridge is inserted within the manifold sump. The magnetic communication is formed between two complementary coded magnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes the latching blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. Movement of the latching blocking structure coded magnet relative to the filter cartridge coded magnet may be perpendicular or parallel with respect to each other. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a shear force is generated between the magnets when the filter cartridge is inserted within the manifold sump housing, allowing for actuation of the latch blocking mechanism against a biasing force, and allowing the latch to move radially inwards against a separate biasing force.

Abstract: A filter media having lignite-derived activated carbon, polyacrylic acid (PAA), a commercially available copper-zinc alloy, and polydiallyldimethylammonium chloride (PolyDADMAC) or Luviquat®, which is Poly[(3-methyl-1-vinylimidazolium chloride)-co-(1-vinylpyrrolidone)], combined and used as suitable replacement for TOG bituminous coal-based activated carbon, silver, and PolyDADMAC. Functional groups in lignite-based activated carbon interact with the polyacrylic acid. Functional groups such as calcium, iron, or aluminum oxide/hydroxide of lignite-based activated carbon interact with PAA, and help hold the PolyDADMAC in place. The additional presence of a copper-zinc alloy enhances the filter anti-microbiological performance.
