Sub-Zero 7042798 Refrigerator Air Purification Cartridge (1 Pack)

The Sub-Zero 7042798 refrigerator air purification cartridge helps manage ethylene gas and odours inside compatible refrigerators. Many fresh foods naturally release ethylene, which can speed up ripening and spoilage. Sub-Zero's air purification system treats the refrigerator air at regular intervals to help maintain a fresher storage environment. This 1-pack contains one replacement cartridge designed for refrigerators equipped with the compatible air purification system.

Contaminants It Reduces

This is an air purification cartridge, not a drinking-water filter. Its stated purpose is to help manage substances that affect the refrigerator's internal air and food freshness.

• Ethylene gas: Helps reduce this naturally occurring gas released by many fresh foods.
• Unwanted odours: Helps reduce odours inside the refrigerator.

These functions are intended to support food freshness. The cartridge does not replace proper food storage, cleaning or safe food-handling practices.
