An assembly for filtering water includes a housing, a water inlet for supplying unfiltered water to the housing, and a water filter including an outer casing attached to the housing in communication with the water inlet and a filter medium within the outer casing, the water filter filtering the unfiltered water through filter medium to provide filtered water. A water outlet is attached to the housing for transferring filtered water from the outer casing to a device via the housing. Some sort of indicia is located on the outer casing, and an optical device detects a feature of the indicia to determine if the water filter is properly installed in the housing. Related refrigeration appliances incorporating such devices are also disclosed.

1. An assembly for filtering water, the assembly comprising: a housing;a water inlet for supplying unfiltered water to the housing;a water filter including an outer casing attached to the housing in communication with the water inlet and a filter medium within the outer casing, the water filter filtering the unfiltered water through filter medium to provide filtered water, the outer casing attached to the housing a rotationally and axially engaging attachment;a water outlet attached to the housing for transferring filtered water from the outer casing to a device via the housing;a graphical indicia located on a surface of a side of the outer casing; andan optical device positioned adjacent to the outer casing for detecting a feature of the graphical indicia to determine if the water filter is properly attached to the housing, wherein the feature includes a location of the graphical indicia, and wherein the optical device is positioned such that incomplete detection of the graphical indicia indicates the water filter is not properly attached to the housing. 2. The assembly of claim 1, wherein the assembly is configured to discontinue operation so that no further water is provided through the water inlet when the optical device determines the water filter is not properly attached to the housing. 3. The assembly of claim 1, wherein the feature detected includes date information of the graphical indicia, so that a proper duration of use of the water filter can be determined. 4. The assembly of claim 1, wherein the outer casing is attached to the housing a screw-type attachment. 5. The assembly of claim 1, wherein the optical device is a camera. 6. The assembly of claim 1, further including a controller in communication with the optical device to determine the proper installation has occurred. 7. The assembly of claim 1, wherein the housing is attachable to a refrigeration appliance. 8. A refrigeration appliance comprising: a refrigerated compartment having a door;a housing mounted within the refrigerated compartment;a water inlet for supplying unfiltered water to the housing;a water filter including an outer casing attached to the housing in communication with the water inlet and a filter medium within the outer casing, the water filter filtering the unfiltered water through filter medium to provide filtered water, the outer casing attached to the housing a rotationally and axially engaging attachment;a water outlet attached to the housing for transferring filtered water from the outer casing to a device via the housing;a graphical indicia located on a surface of a side of the outer casing; andan optical device positioned adjacent to the outer casing for detecting a feature of the indicia to determine if the water filter is properly attached to the housing, wherein the feature includes a location of the graphical indicia, and wherein the optical device is positioned such that incomplete detection of the graphical indicia indicates the water filter is not properly attached to the housing. 9. The refrigeration appliance of claim 8, further including a controller in communication with the optical device to determine the proper installation has occurred. 10. The refrigeration appliance of claim 9, wherein the optical device is a camera. 11. The refrigeration appliance of claim 10, wherein the assembly is configured to discontinue operation so that no further water is provided through the water inlet when the optical device determines the water filter is not properly attached to the housing. 12. The refrigeration appliance of claim 10, wherein the feature detected includes date information of the graphical indicia, so that a proper duration of use of the water filter can be determined. 13. The refrigeration appliance of claim 10, wherein the featured detected includes a shape of at least a portion of the outer casing. 14. An assembly for filtering water, the assembly comprising: a housing;a water inlet for supplying unfiltered water to the housing;a water filter including an outer casing in communication with the water inlet and a filter medium within the outer casing, the water filter filtering the unfiltered water through filter medium to provide filtered water, wherein the outer casing is attached to the housing a screw-type connection;a water outlet attached to the housing for transferring filtered water from the outer casing to a device via the housing;a graphical indicia located on a surface of a side of the outer casing; andan optical device positioned adjacent to the outer casing for detecting a feature of the indicia to determine if the water filter is properly screwed into the housing and attached to the housing in a proper orientation, wherein the feature includes a location of the graphical indicia, and wherein the optical device is positioned such that incomplete detection of the graphical indicia indicates the water filter is not properly attached to the housing. 15. The assembly of claim 14, wherein the optical device is rigidly attached to the housing. 16. The assembly of claim 14, wherein the housing further comprises a wall portion extending adjacent to the side of the outer casing, and wherein the optical device is attached to the wall portion of the housing. 17. The assembly of claim 14, wherein the assembly is configured to discontinue operation so that no further water is provided through the water inlet when the optical device determines the water filter is not properly screwed into the housing and attached to the housing in a proper orientation.
