Product Description
The Sub-Zero 7042798 Air Purification Cartridge is designed to actively clean the air inside your refrigerator— not just mask odors. Installed inside your Sub-Zero unit, it works continuously to maintain a cleaner internal environment that helps food stay fresh longer.
Unlike passive refrigerator deodorizers, this cartridge uses active air-scrubbing technology inspired by aerospace research. The system automatically filters refrigerator air every 20 minutes, targeting odor-causing molecules and food-spoiling gases before they circulate. It’s an essential maintenance component for preserving the performance, hygiene, and food-preservation standards Sub-Zero refrigerators are known for.
