Abstract

The present disclosure relates to a 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, a latching mechanism and a water manifold, the latching mechanism providing a unique mechanism interface between a manifold and a filter cartridge, the latching mechanism providing a compact and simple mechanism between the 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.
