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.

1. A disposable filter cartridge comprising: a first locking member;a second locking member;a filter cap including at least one partial flange configured to twist into a recess defined by an interference fit of the first locking member and the second locking member to secure the filter cap within the recess; anda filter container for receiving a filter therein, wherein the filter container is threadably coupled to the filter cap and includes a lock for retaining the filter container to the filter cap;wherein the first locking member comprises an inlet/outlet attachment including an inlet port and an outlet port extending therefrom, the inlet port configured to allow a flow of fluid into the filter and the outlet port configured to allow the flow of fluid out of the filter;wherein the outlet port is a centrally located port connected to a central channel in the filter cap to allow fluid to flow along a longitudinal axis of the filter;wherein the inlet port is offset from the centrally located port and fluidly connects to one or more other channels in the filter cap via a toroidal chamber formed between a bottom of the inlet/outlet attachment and an upper surface of the filter cap; andwherein the second locking member comprises a support bracket. 2. The disposable filter cartridge of claim 1, wherein at least one of the filter cap, first locking member, and second locking member includes an o-ring to form a water-tight seal between the filter and at least one fluid channel defined by the filter cap. 3. The disposable filter cartridge of claim 1, wherein the lock couples the filter container to the filter cap without adhesive and heat treatment. 4. The disposable filter cartridge of claim 1, wherein, when assembled together to form a locking assembly, the inlet/outlet attachment and support bracket define a recess bounded on one side by the lower edge of the inlet/outlet attachment and other side by a rim along an aperture in the support bracket. 5. The disposable filter cartridge of claim 1, wherein the support bracket comprises one or more twist-and-lock features protruding from an edge thereof wherein the twist-and-lock features define a guide path for an end of the filter cap. 6. The disposable filter cartridge of claim 5, comprising: a lock well at the end of each twist-and-lock feature, wherein the lock well engages a complementary feature on the filter cap to secure the filter cap to the support bracket. 7. The disposable filter cartridge of claim 6, wherein each twist-and-lock feature comprises a dislodge aid that facilitates removal of the filter cap from the recess. 8. The disposable filter cartridge of claim 1, further comprising cartridge positioning aids on at least one of the filter cap and the filter container to properly seat the filter in the filter container. 9. The disposable filter cartridge of claim 8, further comprising one or more water shut-off rims and one or more gaskets coupled together to separate and prevent incoming unfiltered water from mixing with and contaminating the filtered water exiting the filter. 10. The disposable filter cartridge of claim 1, wherein the lock on the filter container engages the filter cap to couple the filter container to the filter cap by screwing the filter container to the filter cap. 11. The disposable filter cartridge of claim 10, further comprising an o-ring received in a groove of the filter cap to create a watertight seal between the filter cap and the filter container once the filter cap is locked to the filter container. 12. The disposable filter of claim 1, wherein: the filter cap comprises a cylindrical shoulder that protrudes from a central region of the filter cap;a cylindrical plug extends from a central region of the cylindrical shoulder;a cylindrical inner channel and one or more cylindrical outer channels run through the plug and shoulder, respectively, to the inside of the assembled disposable filter cartridge; andan inflow and outflow separating wall prevents fluid from spilling between the inner channel and the outer channel without flowing through filtration media in a body of the filter container. 13. The disposable filter cartridge of claim 12, wherein the filter cap comprises one or more partial flanges protruding from the shoulder, each partial flange comprising: a mount shoulder,a lodge aid, anda second lock;the mount shoulder, lodge aid and second lock each configured to mount and nest the filter cartridge. 14. The disposable filter cartridge of claim 13, wherein: the filter cap and filter container are configured to be installed into the locking assembly by:inserting the plug into the central aperture in the support bracket; andtwisting the filter container with respect to the locking assembly to cause the partial flanges to engage the twist-and-lock features along the recess defined by the assembled inlet/outlet attachment and the support bracket. 15. The disposable filter cartridge of claim 1, wherein the cartridge is configured such that fluid can travel in through the inlet port, along a linear flow path along the longitudinal axis of the filter container filled with filtration media, and along a return path along an outer edge of the filtration media to the outlet port. 16. The disposable filter cartridge of claim 1, wherein the cartridge is configured such that fluid can travel in through the inlet port, along a path along an outer edge of filtration media in the filter container, through the media, and to the outlet port along a linear return flow path along the longitudinal axis of the filter container.
