The present disclosure relates to a new fluid filter system including, but not limited to, structure for enabling a filter cartridge to be installed and removed from a manifold with a straight line push/pull motion, an innovative latching mechanism and an innovative water manifold, the latching mechanism providing a unique mechanism interface between an innovative manifold and a filter cartridge, the latching mechanism providing a compact and simple mechanism between the innovative manifold and the filter cartridge that significantly reduces the installation and removal force previously found with fluid filtration cartridges by including a low force filter cartridge installation and removal mechanism for utilization by the end consumer and the manifold assembly includes an inlet and an outlet port, the manifold assembly having structure for maintaining a substantially constant volumetric cavity of the fluid filtration system that contains fluid during installation and operation of the filter therein and removal of the filter therefrom and that has an automatic shut-off system, as the inlet water pressure increases past a predetermined desired maximum system operating pressure, the inlet water will automatically be shut-off, i.e., will not flow into (or out of) the filter cartridge.

A fluid filtration system for enabling a filter cartridge to be installed and removed from a manifold by linear translation of the filter cartridge, the fluid filtration system comprising: a manifold assembly having an inlet port and an outlet port, wherein at least one of the inlet port or the o

1. A fluid filtration system for enabling a filter cartridge to be installed and removed from a manifold by linear translation of the filter cartridge, the fluid filtration system comprising: a manifold assembly having an inlet port and an outlet port, wherein at least one of the inlet port or the outlet port has the capability to translate relative to the manifold assembly; anda filter installation and removal mechanism including a latching mechanism, the mechanism being located on the manifold assembly to: (i) latch the filter cartridge into engagement with the manifold assembly by linear translation of the filter cartridge toward the manifold assembly; and(ii) unlatch the filter cartridge from engagement with the manifold assembly by linear translation of the filter cartridge toward the manifold assembly. 2. The fluid filtration system of claim 1, wherein the relative translation between the at least one of the inlet port or the outlet port and the manifold assembly is such that a fluid trapped in the inlet port or the outlet port can translate and prevent compression of the fluid during: (i) installation of the filter cartridge into the manifold assembly;(ii) operation of the fluid filtration system after the filter cartridge is installed; and(iii) removal of the filter cartridge from the manifold assembly. 3. The fluid filtration system of claim 2, wherein the inlet port translates relative to the manifold assembly, the fluid filtration system further comprising: an automatic shut-off system, operatively connected to the manifold assembly, wherein as an inlet fluid pressure increases past a predetermined desired maximum system operating pressure, the inlet port translates in the manifold assembly away from the filter cartridge such that inlet fluid is automatically shut-off and fluid will not flow into the filter cartridge. 4. The fluid filtration system of claim 1 comprising a filter cartridge, wherein the manifold assembly further comprises a mounting bracket and an alignment collar connected to the mounting bracket; wherein the filter cartridge further comprises one or more alignment members that interface with the alignment collar to align the filter cartridge with the manifold assembly. 5. The fluid filtration system of claim 4 wherein the one or more alignment members comprises a protrusion on the outer surface of the filter cartridge. 6. The fluid filtration system of claim 4 wherein the alignment collar comprises one or more slots to assist in aligning the filter cartridge with the alignment collar. 7. The fluid filtration system of claim 6 wherein the filter cartridge further comprises a cartridge latching structure formed on the filter cartridge outer surface to interact with the latching mechanism, wherein the cartridge latching structure passes through the one or more slots to insert the filter cartridge into the manifold assembly. 8. The fluid filtration system of claim 7 wherein the cartridge latching structure comprises one or more projections that pass through the one or more slots to insert the filter cartridge into the manifold assembly. 9. The fluid filtration system of claim 6 wherein the one or more alignment members comprises a protrusion on the outer surface of the filter cartridge that interfaces with the one or more slots on the alignment collar. 10. The fluid filtration system of claim 9 wherein the filter cartridge further comprises a cartridge latching structure formed on the filter cartridge outer surface to interact with the latching mechanism, wherein the cartridge latching structure passes through the one or more slots to insert the filter cartridge into the manifold assembly. 11. The fluid filtration system of claim 10 wherein the cartridge latching structure comprises one or more projections that pass through the one or more slots to insert the filter cartridge into the manifold assembly. 12. The fluid filtration system of claim 1 wherein the manifold assembly comprises a compression spring that is biased against translation of the filter cartridge into the manifold assembly. 13. The fluid filtration system of claim 1 wherein the manifold assembly comprises a shut-off valve that is opened by translation of the filter cartridge into the manifold assembly, and closed by translation of the filter cartridge out of the manifold assembly. 14. The fluid filtration system of claim 13 wherein the shut-off valve comprises a spring that biases the shut-off valve toward the filter cartridge.
