Sub-Zero 4204490 Water Filter & 7007067 Air Purification Cartridge Combo Pack

Maintain two parts of your refrigerator's filtration system with this Sub-Zero air and water filter kit. It combines the 7007067 air purification cartridge with the 4204490 refrigerator water filter, offering a practical option when both components need attention.

The air cartridge helps manage ethylene gas and unwanted odours within compatible refrigerators. The water cartridge helps reduce chlorine taste and odour in dispensed water.
