Abstract: A fluid filter assembly for a water dispensing faucet includes a housing assembly that is constructed and arranged to connect to a water dispensing faucet, a cover assembly that is threadedly attachable to the housing assembly for defining an interior receiving space therebetween and a replaceable filter cartridge installed into the receiving space and being constructed and arranged for filtering a flow of water before that water is delivered to the dispensing faucet. A plurality of reed switches are utilized that are responsive to changes in magnetic flux in order to provide electronic indications of filter status. Some of these electronic indications include the filter cartridge status in terms of its useful life, when a non-approved filter cartridge is installed, when there is no filter cartridge installed, when there is a water leak within the fluid filter assembly, and when one used filter cartridge has been replaced by a new filter cartridge.

Abstract: A rotational limit stop comprising a substantially circular disc having an upper surface, a lower surface and a perimeter surface, the perimeter surface containing a plurality of teeth on one portion thereof, a central aperture passing through the center of the circular disc, and a plurality of resilient spring legs extending downwards from the lower surface of the disc, such that the resilient spring legs of the rotational limit stop flex to accommodate the compression forces as a faucet assembly containing the rotational limit stop is being assembled.
