a plurality of partitions positioned within the internal chamber, extending between the parallel main walls to form multiple sub-chambers, each partition defining a blocked end and an open end, the partitions spaced apart along a direction between the end walls to form a first group where the blocked end is connected to one of the side walls and a second group where the blocked end is connected with the other side wall, and wherein the partitions define a non-linear pathway for the flow of water through the filter cartridge between the fluid inlet and the fluid outlet; and

filter media positioned in the sub-chambers of the filter cartridge, the filter media configured to remove dissolved solids from water travelling through the filter cartridge.

2. The filter cartridge assembly for the ice making appliance as in claim 1 , further comprising a filter manifold defining a slot for removable insertion of the filter cartridge.

3. The filter cartridge assembly for the ice making appliance as in claim 2 , wherein the filter manifold further comprises a latch mechanism for releasably securing the filter cartridge within the filter manifold.

4. The filter cartridge assembly for the ice making appliance as in claim 3 , wherein the latch mechanism comprises a resilient latch arm supported on a wall of the filter manifold and extending away from the filter manifold, the latch arm including a stop extending orthogonally from the latch arm and positioned to selectively block the filter cartridge from removal from the filter manifold.

5. The filter cartridge assembly for the ice making appliance as in claim 3 , wherein the latch mechanism comprises a pair of resilient latch arms, each latch arm supported on one of the main walls and extending away from the filter manifold, each latch arm including a stop extending orthogonally from the latch arm and positioned to selectively block the filter cartridge from removal from the filter manifold.

6. The filter cartridge assembly for the ice making appliance as in claim 2 , further comprising a filter manifold defining

a slot for removable insertion of the filter cartridge;

a fluid inlet socket for releasable receipt of the fluid inlet of the filter cartridge; and

a fluid outlet socket for releasable receipt of the fluid outlet of the filter cartridge.

7. The filter cartridge assembly for the ice making appliance as in claim 6 , wherein the fluid inlet and the fluid outlet of the filter cartridge each include an O-ring type seal for mating with the fluid inlet socket and the fluid outlet socket, respectively, to prevent leaking of water.

8. The filter cartridge assembly for the ice making appliance as in claim 1 , further comprising a plurality of porous media portions, each porous media portion positioned at one of the open ends of the first group of partitions to allow water to flow through the sub-chambers of the filter cartridge along the non-linear pathway while separating filter media between adjacent sub-chambers.

9. The filter cartridge assembly for the ice making appliance as in claim 8 , wherein the porous media portions comprise non-woven fiber pads.

10. The filter cartridge assembly for the ice making appliance as in claim 1 , wherein the first group of partitions are connected to only one of the side walls and the second group of partitions are connected to both of the sides walls.

11. The filter cartridge assembly for the ice making appliance as in claim 10 , wherein each partition of the second group of partitions defines at least one aperture within the partition for the flow of water.

12. The filter cartridge assembly for the ice making appliance as in claim 1 , wherein the filter media comprises a cation resin and an anion resin removed dissolved solids from the water.

13. An ice making appliance, comprising

a cabinet defining an interior;

a door supported by the cabinet and configured for allowing selective access to the interior;

an ice bin located within the interior of the cabinet and positioned to collect ice created by the ice making appliance;

a cooling system for converting water from a liquid to ice;

a filter cartridge assembly for removing dissolved solids from the water, the filter cartridge assembly comprising

a filter cartridge having a rectilinear shape and defining an internal chamber, the filter cartridge having a pair of generally parallel main walls separated by the internal chamber and connected by a first pair of end walls and a second pair of side walls;

a fluid inlet connected with the filter cartridge and providing for the flow of water into the internal chamber;

a fluid outlet connected with the filter cartridge and providing for the flow of water out of the internal chamber;

a plurality of partitions positioned within the internal chamber and extending between the parallel main walls to form multiple sub-chambers, the partitions configured to form a serpentine pathway for the flow of water through the filter cartridge between the fluid inlet and the fluid outlet; and

filter media positioned in the sub-chambers of the filter cartridge, the filter media configured to remove dissolved solids from water travelling through the filter cartridge.

14. The ice making appliance as in claim 13 , further comprising a filter manifold defining a slot for removable insertion of the filter cartridge.

15. The ice making appliance as in claim 14 , wherein the filter manifold further comprises a latch mechanism for releasably securing the filter cartridge within the filter manifold.

16. The ice making appliance as in claim 15 , wherein the latch mechanism comprises a resilient latch arm supported on one of the main walls and extending away from the filter manifold, the latch arm including a stop extending orthogonally from the latch arm and positioned to selectively block the filter cartridge from removal from the filter manifold.

17. The ice making appliance as in claim 16 , wherein the latch mechanism comprises a pair of resilient latch arms, each latch arm supported on one of the main walls and extending away from the filter manifold, each latch arm including a stop extending orthogonally from the latch arm and positioned to selectively block the filter cartridge from removal from the filter manifold.

18. The ice making appliance as in claim 17 , wherein the filter manifold further comprises:

a fluid inlet socket for releasable receipt of the fluid inlet of the filter cartridge; and

a fluid outlet socket for releasable receipt of the fluid outlet of the filter cartridge.

19. The filter cartridge assembly for an ice making appliance as in claim 18 , wherein the fluid inlet and the fluid outlet of the filter cartridge each include an O-ring type seal for mating with the fluid inlet socket and the fluid outlet docket, respectively, to prevent leaking of water.
