Special Features

Replaces the Older 7007067 Cartridge

The Sub-Zero 7042798 is the manufacturer's direct replacement for part number 7007067. If the older number appears on your existing cartridge or appliance documentation, verify your model's compatibility before purchasing.

Air Purification for Compatible Refrigerators

The Sub-Zero air purification system helps manage ethylene gas and odors inside the refrigerator. The system treats the air approximately every 20 minutes when operating as intended.

Helps Support Fresh Food Storage

Ethylene is a naturally occurring gas released by many fruits and vegetables. Because it can accelerate ripening, managing ethylene is one way the Sub-Zero air purification system supports refrigerator food storage.
