Abstract

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.

Claims (15)

1 . A filtration system comprising: a modular filter assembly having a manifold head and a filter cartridge assembly;

said filter cartridge assembly including a filter housing sealingly containing a filter media, said filter housing including an annular collar fixedly attached to said filter housing, or integral therewith, for mating to said manifold head, said annular collar having a top surface, internal threads facing radially inwards, and at least one aperture or recessed indent facing radially outwards, and having a rotation coinciding with said filter housing, and said at least one aperture or recessed indent adapted to receive a protrusion or lead-in tab for securing said filter cartridge assembly from further rotation when secured in said manifold head; and

said manifold head having a receiving portion with external threads for threadingly receiving said filter housing annular collar internal threads, a top portion fluid access port capable of releasably joining to an adjacent manifold head top portion fluid access port by a manifold union or conduit, which allows said fluid access ports to link in fluid communication to one another.

2 . The filtration system of claim 1 wherein said manifold head includes ingress and egress ports adapted for receiving either said manifold union or conduit to continue water flow outside the manifold head, or a conduit plug to cease water flow from a given port, or an input/output conduit for receiving fluid ingress or dispensing fluid egress.

3 . The filtration system of claim 2 wherein said manifold union or conduit, said conduit plug, and said input/output conduit are arranged on said manifold head to allow fluid filtration in a series configuration or a parallel configuration.

4 . The filtration system of claim 1 wherein said manifold union or conduit includes spaced ribs to secure O-rings for a watertight seal of said manifold union or conduit to said manifold head.

5 . The filtration system of claim 1 wherein said annular collar at least one aperture or recessed indent being in a partial circumferential arcuate segment to facilitate insertion of said filter cartridge assembly into said manifold head.

6 . The filtration system of claim 1 wherein said manifold head is integral with a support bracket for holding and/or supporting said manifold head and said filter cartridge assembly.

7 . The filtration system of claim 6 wherein said support bracket or said manifold head includes at least one inwardly, radially extending arcuate segment having a radius of curvature approximately equal to a radius of curvature for said annular collar.

8 . A filtration platform comprising:

at least two filter cartridge assemblies, each including a filter housing sealingly containing a filter media, said filter housing including an annular collar for mating to a respective manifold head, said annular collar fixedly attached to said filter housing, or integral therewith, having a top surface, internal threads facing radially inwards, and at least one aperture or recessed indent positioned within said annular collar below said top surface, and below at least a portion of said internal threads, said at least one aperture or recessed indent facing radially outwards, and having a rotation coinciding with said filter housing, and said at least one aperture or recessed indent adapted to receive a resilient protrusion or lead-in tab for securing said filter cartridge from further rotation;

said respective manifold head for each of said at least two filter cartridge assemblies, said manifold head includes a top portion fluid access port in fluid communication with an adjacent manifold head top portion fluid access port, which allows each filter cartridge assembly to link in fluid communication to one another, and a receiving threaded portion for threadingly securing said filter housing.

9 . The filtration platform of claim 8 wherein said manifold heads are supported by, or integral with, a support bracket.

10 . The filtration platform of claim 8 wherein each of said manifold heads includes ingress and egress ports adapted for receiving either a manifold union or conduit to continue water flow outside the manifold head, or a conduit plug to cease water flow from a given port, or an input/output conduit for receiving fluid ingress or dispensing fluid egress.

11 . The filtration platform of claim 8 wherein said resilient protrusion or lead-in tab comprises a resilient arcuate lock/release lever insertable within said manifold.
