SUB-ZERO Air Purification Cartridge

Maintaining the peak flavor and texture of fresh produce is the single-minded mission of Sub-Zero refrigeration. From the moment a fig is picked, a clock begins to tick, and Sub-Zero is dedicated to prolonging that fleeting freshness. The air purification system in Sub-Zero refrigerators is designed to scrub the air of mold, viruses, and bacteria, contaminants too small for conventional filters, as well as reducing the ethylene gas that hastens food spoilage.

Developed based on NASA technology, the Sub-Zero refrigerator air purification cartridge operates on a 20-minute cycle to ensure constant freshness. The old part number 7007067 and the new part number 7042798 are the same unit and will fit the same refrigerators. Sub-Zero's Authentic Factory Certified Microbiological Purification System, with part numbers 4204490, 7023812, and 7042798, is available in a convenient combo pack (7012333).

Maintaining the optimal temperature and humidity is only part of the preservation story. Sub-Zero's pioneering refrigeration technology goes beyond simply keeping food cold, scrubbing the air of impurities to ensure fresher, more flavorful food. As an added note, during the shipment process, the carbon from inside the unit may deposit on the exterior, which is a normal occurrence and will not affect the performance of the unit. Customers are advised to clean the unit with a paper towel before installation.

The Sub-Zero air filtration system is compatible with all models, providing a revolutionary solution to preserving the freshness and flavor of food. With a simple maintenance process, Sub-Zero customers can enjoy the benefits of this advanced technology, ensuring their produce and other perishables stay fresher for longer.
