ABSTRACT:
An apparatus for filtering water dispensed from an appliance (e.g. a refrigerator) includes a low-profile filter cartridge (or a bank of filter cartridges) releasably connected to a manifold assembly. The manifold assembly is in communication with the water inlet of appliance and routs the filtered water to points of use. A water usage sensor in the manifold monitors the filter cartridge life and alerts the user when it is time to replace the filter. A latching mechanism includes a latching member200on the cartridge and a linearly moveable actuator174for releaseably securing the filter cartridge to the manifold assembly. A flow control valve ensures that the water circuit remains closed when the filter cartridge is removed from the manifold.
