<p>A method an apparatus for filtering water dispensed by a water dispensing appliance comprises a low-profile filter cartridge (102) releasably connected to a manifold assembly (110). The manifold assembly (110) is in communication with the wafer inlet (112) to the appliance and routs the filtered water to points of use in the appliance. The manifold assembly (110) includes water usage sensor (168) to monitor filter cartridge life and relay that information to the appliance, which will then alert the user when it is necessary to replace the filter cartridge (102). A latching mechanism (106) is included to releasably secure the filter cartridge (102) to the manifold assembly (110). A flow control valve (140) ensures that the water circuit remains closed when the filter cartridge (102) is removed from the manifold assembly (110). The cartridge (102) and manifold assembly (110) include registration features to prevent reverse installation of the filter cartridge (102).</p> |
