A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

Modular filtration platform

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.

Filter housing with filter key attachment

A 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 influent and effluent piping, such as within a refrigerator. The 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.

Push filter with floating key lock

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.

A proportioning valve for a reverse osmosis system that controls the production of product water by the differential pressure across the purification membrane. By sensing increasing tank pressure to actuate the proportioning valve, the flow of waste water is restricted. Placement of seals within the cavity of the valve, as well as placement of waste water inlet and outlet ports, protects tension components that provide reverse tank pressure from waste water exposure. A needle valve assembly responsive to an actuating assembly that senses tank pressure removes the need for an inlet tank water port while restricting water flow.

Variable drain flow restrictor

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.
