The 4204490 water filter is NSF 42 and 53 certified to reduce chlorine taste and odor, lead, and other contaminants through activated carbon block filtration. The 7042798 air cartridge works alongside the water filter to reduce odors inside the refrigerator compartment, keeping stored food fresher for longer. Both cartridges are specific to compatible Sub-Zero models and are not interchangeable with other brand filter systems. One detail worth confirming before ordering: always verify both part numbers against your refrigerator model to ensure the combo pack is the correct replacement for your unit.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" bis_size='{\"x\":12,\"y\":201,\"w\":560,\"h\":58,\"abs_x\":300,\"abs_y\":309}'\u003e\u003cspan bis_size='{\"x\":12,\"y\":202,\"w\":493,\"h\":57,\"abs_x\":300,\"abs_y\":310}'\u003eWhy Choose the Sub-Zero 4204490 Water Filter \u0026amp; 7042798 Air Cartridge Combo Pack\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp dir=\"ltr\" bis_size='{\"x\":12,\"y\":271,\"w\":560,\"h\":78,\"abs_x\":300,\"abs_y\":379}'\u003e\u003cspan bis_size='{\"x\":12,\"y\":271,\"w\":532,\"h\":77,\"abs_x\":300,\"abs_y\":379}'\u003eReplacing both the water filter and air cartridge at the same time maintains consistent filtration across both systems and eliminates the risk of one saturated cartridge undermining the performance of a freshly replaced one.
