Sub-Zero 4204490 Refrigerator Water Filter Replacement - 3 Pack

Plan ahead for future filter changes with this three-cartridge Sub-Zero 4204490 water filter bundle. Each filter is made for compatible Sub-Zero refrigerator systems and helps improve the taste and smell of dispensed water by reducing chlorine taste and odour. The cartridges use a twist-in connection for matching filter housings, making them suitable for routine maintenance when the correct part is selected.
