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.

How the Air Purification System Works
  1. Draws internal air into the purification system
  2. Passes it through the 7042798 cartridge
  3. Neutralizes odor molecules and ethylene gas
  4. Redistributes cleaner air throughout the unit

This continuous cycle helps reduce odor transfer, slow spoilage of fruits and vegetables, and maintain a fresher overall refrigerator interior.
