OEM part description
Genuine Sub-Zero two-prong push-in water filter for early Classic BI refrigeration. This CTO cartridge fits the original push-in filter manifold and reduces unwanted color, taste, and odor from the water used for filtered ice and drinking water.
Part details
The early Classic filtration system was designed around a specific two-prong cartridge and water-flow path. A genuine Sub-Zero filter gives you the cartridge Sub-Zero specifies for that manifold, rather than relying on an aftermarket filter that merely claims to fit. Proper cartridge fit matters because the filter must seat and seal correctly while maintaining water flow to the dispenser and icemaker.
The genuine CTO filter also preserves the filtration function intended for this generation of Sub-Zero refrigeration—reducing unwanted taste and odor before the water reaches your glass or freezes into ice.
