OEM part description
Genuine Sub-Zero twist-in water filter for select Classic, Designer, and PRO refrigeration. This cartridge was developed for the Sub-Zero filtration system and supplies filtered water to applicable dispensers and icemakers while reducing chlorine taste and odor, particulates, and a broad range of additional tested contaminants.
Part details
The filter is the last treatment stage your household water passes through before it reaches the refrigerator dispenser or freezes into ice. The genuine Sub-Zero cartridge is more than a cartridge that physically fits the opening—it is the filter Sub-Zero specifies and tests as part of the appliance's filtration system.
Factory performance documentation covers reduction of chlorine taste and odor and particulate matter as well as contaminants including lead, mercury, cysts, asbestos, turbidity, atrazine, benzene, carbofuran, lindane, toxaphene, and other listed substances. The system is rated for up to 750 gallons or approximately one year under normal conditions.

Tech Tip: A cartridge that physically twists into the manifold is not necessarily equivalent to the genuine filter's tested performance. For a premium Sub-Zero refrigeration system, use the cartridge specified for the appliance and reset the water-filter monitor after installation.
