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

The Sub-Zero 7042798 air purification cartridge is a replacement air filter designed for compatible Sub-Zero refrigerators equipped with the factory-installed air purification system. Developed around technology based on NASA research, the Sub-Zero air purification system helps remove ethylene gas and odors from the refrigerator interior. Ethylene is naturally released by many fresh foods and can accelerate ripening and spoilage. The system treats the refrigerator air approximately every 20 minutes, helping support a fresher food-storage environment. The 7042798 cartridge replaces the previous part number 7007067 and is designed to last approximately one year under normal use. Before ordering, verify that your refrigerator has the air purification system and that this replacement cartridge is suitable for your specific model.

Key Features

Helps Manage Ethylene Gas and Odors

The Sub-Zero 7042798 refrigerator air filter works with the appliance's air purification system to help remove ethylene gas and odors. Because ethylene can accelerate the ripening of certain fruits and vegetables, managing it is an important part of Sub-Zero's approach to food preservation.

Supports a Fresher Refrigerator Environment

The air purification system treats refrigerator air approximately every 20 minutes. This helps manage odors and ethylene within compatible refrigerator compartments, supporting the storage environment for fresh food.

Direct Replacement for Part Number 7007067

If your existing Sub-Zero air purification cartridge is labeled 7007067, part number 7042798 is the manufacturer's designated replacement. Check your appliance's documentation or existing cartridge before ordering.

Approximately One-Year Service Life

Sub-Zero recommends replacing the air purification cartridge approximately once a year or when the refrigerator's air purification indicator signals that replacement is needed. Actual replacement timing should follow your model's instructions.

Straightforward Cartridge Replacement

The cartridge fits into the designated air purification compartment of compatible refrigerators. Follow the appliance-specific instructions to remove the old cartridge, install the new one, and reset the filter-life indicator when required.
