Part Description
This replacement set includes genuine Sub-Zero water filter 4204490 and air purification cartridge 7042798. The water filter is designed to reduce chlorine taste, odor, particulates, and additional contaminants identified in its NSF certification.
The air purification cartridge is designed for Sub-Zero's integrated air purification system, helping maintain the intended air treatment within the refrigerator compartment.
Part details
Both filtration systems serve different purposes. The water filter treats water supplied to the appliance's ice maker and dispenser, where equipped, while the air purification cartridge works with the refrigerator's air treatment system.
