This two-cartridge set includes the Sub-Zero 4204490 water filter and 7042798 air purification cartridge for compatible refrigerators that use both components. The water filter helps improve water taste by reducing chlorine taste and odor, while the air purification cartridge works with the built-in air system to help manage ethylene gas and refrigerator odors.

Before purchasing, check your existing cartridges or refrigerator documentation to confirm that your appliance requires the 4204490 water filter and 7042798 air cartridge.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eProduct Details\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eManufacturer:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Sub-Zero\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eCombo Pack Includes:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 1 water filter and 1 air purification cartridge\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eWater Filter:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 4204490\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eAir Purification Cartridge:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 7042798\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003ePrevious Air Cartridge Number:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 7007067\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eWater Filter Purpose:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Chlorine taste and odor reduction and particulate filtration\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eAir Cartridge Purpose:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Helps manage ethylene gas and odors\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eTypical Maintenance Schedule:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Follow the appliance's filter indicators and manufacturer instructions; both components are generally maintained on an approximately annual schedule\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Compatible Sub-Zero refrigerators requiring both replacement cartridges\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003eSpecial Features\u003c\/span\u003e\u003c\/h2\u003e\n\u003ch3\u003e\u003cspan\u003eConvenient Water and Air Filter Replacement\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eInstead of sourcing two cartridges separately, this Sub-Zero 4204490 and 7042798 combo pack brings both replacement components together.
