Abstract

A water filter cartridge assembly for fluid filtration which may be attached to, and removed from an appliance water filter manifold assembly of an appliance, typically by a push-actuated release. The water filter cartridge assembly has a filter housing, and an ingress port and egress port extending therefrom. Each of the ingress port and the egress port typically comprise a port portion having a varying radial diameter. The water filter cartridge assembly further comprises a connection assembly that is structured to establish an electrical connection between the connection assembly and a controller of the appliance. Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.
