Filter unit

A refrigerator includes a filter, a receiver, a manifold, and a cam. The filter has a handle extending therefrom. The receiver defines a cavity configured to receive the filter. The manifold is configured to engage an opposing end of the filter relative to the handle via axial rotation of the filter. The manifold is configured to pivot upward to transition the filter to an activated position. The manifold is configured to pivot downward to transition the filter to a deactivated position. The cam is configured to interfere with the handle in response to partial axial rotation of the filter to prevent the filter from pivoting upward to the activated position. The cam is configured to provide clearance for the handle in response to full axial rotation of the filter to facilitate the filter pivoting upward to the activated position.

Refrigerator appliance

A filter unit includes a body portion that receives a water filter. An engaging portion is coupled to the body portion. A bypass actuator rotates relative to the engaging portion to rotationally and axially operate a bypass valve of a fluid manifold. The bypass actuator drives axial engagement of the engaging portion with a valve assembly of the fluid manifold. The bypass actuator extends through the body portion and the engaging portion.

Filter assembly

A water treatment apparatus that includes: at least one module which operatively and selectively treats one or both of an original household hot water received from the household hot water line and water flowing through the module and treats cold water received from an original household cold water line that flows through; a process control unit whereby a user selects a desired treatment option for the water flowing through the apparatus to be dispensed to the user; one or more plumbing connections which operatively divert the original household hot and cold water flow to the user selected water treatment module so as to dispense to the user the selected treated water; and one or more valves which operatively cooperate with the process control unit to direct the water flow within the apparatus so as to provide the user with the selected treated water.
