Abstract: Embodiments of the technology disclosed herein include disposable filter cartridges for use with a water dispenser that dispenses hot water, flavored water, and chilled, sparkling water. An exemplary filter cartridge may be assembled by screwing or inserting a filter into filter cap until the filter cap engages a lock, such as an agnail lock, on the filter. Once engaged, the lock permanently secures the filter to the filter cap without adhesives, heat treatment, or curing. The filter cartridge includes one or more protrusions, or partial flanges, that twist into a recess formed by an injection-molded, two-piece locking assembly affixed to the water dispenser. Twisting the filter cartridge to a predetermined angle with respect to the locking assembly locks the filter cartridge into place. In some embodiments, the locking assembly and the filter cartridge audibly “click” or “snap” to indicate that they are secured together.

Abstract: An apparatus is disclosed for dispensing water including: a main inlet configured to receive water from a source; a chilled water line, including: an in-line carbonator; a carbonator water inlet valve configured to selectively direct water from the main inlet to the carbonator; a carbonator gas inlet valve configured to selectively direct carbonating gas to the carbonator; and a chilled water line outlet. The apparatus may be integrated in a refrigerator or other major appliance.

Abstract: The present invention relates generally to fluid filtration, such as, for example, filtration systems and units (and components thereof) and filtration methods.

Abstract: In one aspect, an apparatus is disclosed for dispensing water including: a first inlet, a second inlet, and a third inlet; a chamber in fluid communication with first, second and third inlets, and a dispenser nozzle in fluid communication with the chamber.
