Waterdrop refrigerator water filters

Independent aftermarket brand. Its cartridges are cross-referenced to an OEM part number, and some carry a recognition chip — check the listing against your housing, not the brand name.

Waterdrop does not build refrigerators. These are aftermarket cartridges made to replace the original part in a specific housing — each one lists the OEM part numbers it substitutes, and the refrigerators it fits.
