A filter cartridge for operatively coupling to an appliance interface for treating fluid to the appliance. The filter cartridge includes a cartridge housing and a filter media contained within the cartridge housing. An engagement fitting extends from the cartridge housing. The engagement fitting to be received by the interface. The engagement fitting includes a base portion and a sealing member. The base portion has an inlet aperture on a first side of the sealing member and an outlet aperture on a second side of the sealing member. An interference member actuator extends axially and distally from one of the first end of the cartridge housing and the first end cap. The interference member actuator is configured to actuate an interference member of the interface from an interference position in which the interface is prevented from being actuated from a bypass mode to a filtering mode to a non-interference position.

A attachment and detachment apparatus removably attaches a filter container containing a filter, as a part of a filtration apparatus that filters fluid with the filter. The filter container includes a first mounting protrusion including a flow path in fluid communication with the filter. The first mounting protrusion includes a rotation center axis. An outer periphery surface of the first mounting protrusion includes at least two curved surfaces respectively formed to be at least a part of an arc about the rotation center axis. The attachment and detachment apparatus includes a first mounting protrusion holding part that holds the first mounting protrusion. The flow path for the fluid is connected to the first mounting protrusion holding part, the first mounting protrusion holding part includes an inner periphery surface corresponding to the curved surface of the outer periphery surface, and a notch communicating the inner periphery surface with an outer side of the first mounting protrusion holding part.

A water purifier includes a water purifier main body having a front panel forming a front surface, first and second side panels forming both side surfaces, a top cover forming an upper surface, a rear cover forming a rear surface, and a base forming a bottom surface and in which a filter is accommodated; a fixed cover provided with an elevation space therein in a vertical direction and fixed to the upper surface of the water purifier main body, a water outlet nozzle exposed to a lower end of the fixed cover, and a filter housing disposed inside the water purifier main body and in which a filter accommodating groove in which the filter is accommodated is concave backward, and in which a downwardly concave filter groove is formed in the base to accommodate the lower end of the filter.

A filtration system interconnection structure includes a filter manifold and a filter cartridge in magnetic communication produced by two complementary correlated magnets capable of generating a magnetic force when in close proximity to one another. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a repulsion force is generated between the magnets when the filter cartridge is inserted within the manifold sump. The magnetic repulsion force may be used to move a blocking mechanism or actuate a latch structure in the manifold to secure the filter cartridge within the manifold sump upon insertion, or to provide non-contacting actuation of a downstream valve so as to permit or prevent the flow of fluid. Utilizing correlated magnetism in a filter interconnect further provides enhanced authentication and/or anti-counterfeiting means to ensure that only authorized or OEM filter cartridges can be installed.
