A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.

The customizable multi-stage water treatment system of claim 1, wherein the keyed mating arrangement includes at least one recess and at least one protrusion configured to matingly correspondingly engage the at least one recess, and wherein the keyed mating arrangement is configured to permit the connector to matingly engage in a fluid tight manner with the first end of the base cartridge, to permit the second end of the base cartridge to matingly engage in a fluid tight manner with the first connector end of the first variable cartridge, and to permit the first receiver end of the first variable cartridge to matingly engage in a fluid tight manner with the second connector end of the second variable cartridge. 3. The customizable multi-stage water treatment system of claim 1, wherein the keyed mating arrangement includes a first keyed mating arrangement between the connector and the base cartridge and a second keyed mating arrangement between the base cartridge and the first variable cartridge, and wherein the first and second keyed mating arrangements are configured to prevent the connector from directly engaging the first variable cartridge and to prevent the first end of the base cartridge from engaging the first coupler end of the first variable cartridge and to prevent the second end of the base cartridge from engaging the connector. 4. The customizable multi-stage water treatment system of claim 3, wherein the keyed mating arrangement further includes a third keyed mating arrangement between the first variable cartridge and the second variable cartridge, and wherein the second and third keyed mating arrangements are configured to prevent the base cartridge from directly engaging the second variable cartridge and to prevent the first coupler end of the first variable cartridge from engaging the second connector end of the second variable cartridge and the first receiver end of the first variable cartridge from engaging the second receiver end of the second receiver cartridge. 5. The customizable multi-stage water treatment system of claim 1, wherein the connector is integral with the base cartridge. 6. The customizable multi-stage water treatment system of claim 1, wherein the connector is configured to be removably and fluidly engaged and disengaged with the first end of the base cartridge bottom by hand, and wherein the second variable cartridge is included in the water treatment system. 7. The customizable multi-stage water treatment system of claim 1, wherein the channel comprises: a base segment extending within the sidewall of the base cartridge between the first end and the second end;a first segment extending within the first wall of the first variable cartridge between the first coupler end and the first receiver end; anda second segment extending within the second wall of the second variable cartridge between the second coupler end and the second receiver end, wherein the base segment, the first segment, the second segment of the channel are substantially aligned to permit fluid to travel there between when the base, the first, and second variable cartridges are engaged with one another. 8. The customizable multi-stage water treatment system of claim 7, wherein the second segment is configured to regulate the rate at which fluid travels through the channel extending through the second variable cartridge, thereby regulating the rate at which fluid travels through the closed circuit and the second treatment medium, and wherein the second segment is configured to correlate with a desired water flow rate for the second treatment medium. 9. The customizable multi-stage water treatment system of claim 7, wherein the base segment and the first segment of the channel are configured to regulate the rate at which fluid travels through the channel extending through the respective base cartridge and first variable cartridge and configured to regulate a residence time the water is in contact with the base, first and second treatment medium, thereby also regulate the rate at which fluid travels through the closed circuit. 10.
