An additive dispensing system for a refrigerator that includes a reservoir configured to contain an additive and an additive outlet in fluid communication with the reservoir. The additive dispensing system is configured to be connected to a refrigerator and is operable to selectively dispense an amount of additive to water dispensed from the refrigerator. The additive dispensing system may be connected to a water filtration system of the refrigerator such that the additive dispensing system may dispense the amount of additive into filtered water dispensed from the refrigerator.

1. A refrigerator comprising: a dispensing cove;a water filtration system disposed within the refrigerator, the filtration system comprising: a water inlet connectable to an unfiltered water source,a water filter in fluid communication with the water inlet, anda first water outlet disposed in the dispensing cove, the first water outlet in fluid communication with the water filter operable to dispense filtered water from the refrigerator at the dispensing cove; andan additive dispensing system comprising: a receptacle connected to the refrigerator at the dispensing cove, the receptacle including a space, anda disposable cartridge removably received within the space, the cartridge including a reservoir, wherein the reservoir contains an additive, and an outlet check valve in fluid communication with the reservoir, wherein the outlet check valve is disposed adjacent to the first water outlet,wherein after the disposable cartridge is positioned within the space of the receptacle, the disposable cartridge is selectively movable within the space of the receptacle along a direction parallel with a longitudinal axis of the disposable cartridge to dispense an amount of additive from the reservoir through the outlet check valve;wherein the additive and filtered water are dispensed from the dispensing cove. 2. The refrigerator of claim 1, further comprising a door. 3. The refrigerator of claim 2, wherein the dispensing cove is disposed within the door. 4. The refrigerator of claim 1, wherein the receptacle is positioned at the dispensing cove such that the outlet check valve dispenses the additive from the disposable cartridge at the dispensing cove. 5. The refrigerator of claim 1, wherein the outlet check valve dispenses the additive from the disposable cartridge into the filtered water within the water filtration system prior to the filtered water exiting the first water outlet. 6. The refrigerator of claim 1, wherein the first water outlet dispenses the filtered water from the water filtration system at the cove in a first stream into a container, and wherein the outlet check valve dispenses the additive from the disposable cartridge at the cove in a second stream into the container that is separate and distinct from the first stream. 7. The refrigerator of claim 1, wherein the additive dispensing system comprises a plurality of receptacles, each including a space, and a plurality of disposable cartridges, each movably received with one of the respective spaces. 8. The refrigerator of claim 1, wherein the disposable cartridge slides within the space in order to dispense the amount of additive from the reservoir. 9. The refrigerator of claim 1, wherein the additive dispensing system comprises a bladder containing the additive that is disposed within the reservoir of the cartridge. 10. The refrigerator of claim 1, further comprising a mechanism that moves the disposable cartridge in the space to actuate the dispensing of the additive from the reservoir. 11. The refrigerator of claim 10, wherein the mechanism is selected from the group consisting of a toggle mechanism, a lever mechanism, a linear cam, and a rotary cam. 12. The refrigerator of claim 11, wherein the mechanism is manually, motively, or electrically activated. 13. The refrigerator of claim 1, further comprising an ice machine connected downstream from the filter. 14. The refrigerator of claim 1, wherein the water filtration system comprises a cold water reservoir that stores filtered water and is disposed between the filter and the first water outlet. 15. The refrigerator of claim 14, wherein the water filtration system comprises a first valve disposed between the cold water reservoir and the first water outlet. 16. The refrigerator of claim 14, wherein the water filtration system comprises a first valve disposed between the cold water reservoir and the first water outlet, and wherein the controller is operable to activate the first valve to control the amount of filtered water to be dispensed from the first water outlet. 17. The refrigerator of claim 16, wherein the controller is operable to control the amount of additive dispensed from the outlet check valve based upon the amount of filtered water dispensed from the first water outlet. 18. The refrigerator of claim 1, further comprising a controller operable to activate the additive dispensing cartridge to dispense an amount of additive. 19. A refrigerator comprising: a door;a dispensing cove disposed within a front surface of the door;a water filtration system comprising: a water inlet,a replaceable water filter cartridge in fluid communication with the water inlet, the water filter cartridge comprising activated carbon,a water reservoir in fluid communication with the water filter cartridge, anda first water outlet in fluid communication with the water filter cartridge and positioned within the dispensing cove such that the first water outlet dispenses filtered water from the refrigerator at the dispensing cove; andan additive dispensing system comprising: a receptacle connected to the refrigerator at the dispensing cove, the receptacle including a space, anda disposable cartridge received within the space, the cartridge including a reservoir, wherein the reservoir contains an additive, and an outlet check valve in fluid communication with the reservoir,wherein once the disposable cartridge is positioned within the space of the receptacle, the disposable cartridge is selectively slidable within the space of the receptacle along a direction parallel with a longitudinal axis of the disposable cartridge to dispense an amount of additive from the reservoir through the outlet check valve;wherein the additive and filtered water are dispensed from the dispensing cove. 20. A refrigerator comprising: a water inlet connectable to an unfiltered water source;a replaceable water filter cartridge in fluid communication with the water inlet, the filter cartridge comprising activated carbon;a first valve in fluid communication with the water filter;a second valve in fluid communication with the water filter;a filtered water outlet in fluid communication with the first valve;an ice maker in fluid communication with the second valve;a receptacle positioned adjacent to the filtered water outlet; andan additive dispensing cartridge movably received within the receptacle, the additive dispensing cartridge comprising: a housing,a reservoir formed by the housing, the reservoir configured to hold an additive,an inlet check valve in fluid communication with the reservoir, andan outlet check valve in fluid communication with the inlet check valve,wherein the additive dispensing cartridge moves within the receptacle to open the outlet check valve to dispense the additive from the reservoir. 21. The refrigerator of claim 20, wherein the additive dispensing cartridge is slidably received with the receptacle such that when the cartridge is actuated, the cartridge slides within the receptacle along a direction parallel with a longitudinal axis of the cartridge in order to selectively dispense an amount of additive from the reservoir through the inlet check valve and out the outlet check valve. 22. The refrigerator of claim 20, further comprising a body, a door hingedly connected to the body, and a cove disposed within the door, wherein the filtered water outlet and the receptacle are positioned within the cove.
