Sub-Zero 7042798 Air Purification Cartridge

The Sub-Zero 7042798 Air Purification Cartridge is a replacement cartridge for newer Sub-Zero refrigerators equipped with the updated air purification housing. It helps reduce food odors, ethylene gas, bacteria, and other airborne impurities inside the refrigerator, while the built-in system continuously circulates air through the cartridge. If your existing cartridge is marked 7042798, this replacement is designed for that specific housing.

Specifications

Made for the 7042798 Housing

The 7042798 is designed for the updated air purification housing found in newer Sub-Zero refrigerator generations. Because Sub-Zero uses different cartridge housings, the 7042798 should not be selected based on appearance alone. Check the part number printed on your current cartridge before ordering.

Fresher Air Inside Your Refrigerator

Food odors can linger when different ingredients share the same refrigerator compartment. The 7042798 air purification cartridge helps reduce unwanted odors as air passes through the refrigerator's built-in purification system.

Helps Reduce Ethylene Gas

Fresh fruits and vegetables naturally release ethylene gas as they ripen. The air purification system helps reduce ethylene gas inside compatible Sub-Zero refrigerators, supporting a fresher environment for stored produce.

Continuous Air Purification

The cartridge works with the refrigerator's active air purification system rather than simply sitting inside the compartment as a passive deodorizer. The system scrubs the refrigerator air approximately every 20 minutes, helping maintain consistent air purification throughout normal use.

Simple Replacement

Replacing the 7042798 does not require special tools or refrigerator modifications. The cartridge is designed to push or slide into the compatible housing, making routine replacement straightforward.

7042798 vs. 7007067

The 7042798 and 7007067 serve similar air purification functions, but they use different housing formats. The 7042798 is associated with newer Sub-Zero models, while the 7007067 is used with earlier systems. They are not interchangeable, so the part number on your existing cartridge is the safest way to identify the correct replacement.

Built for Newer Sub-Zero Systems

The Sub Zero 7042798 air cartridge is designed for compatible Sub-Zero refrigerators, freezers, and wine storage units that have the corresponding air purification slot. Not every Sub-Zero model includes an air purification system, so check for the compatible cartridge housing before ordering.

If your existing cartridge is labelled 7042798, this is the correct part-number family to look for. If it says 7007067, use the 7007067 replacement instead. Matching the printed part number helps avoid ordering a cartridge designed for a different housing generation.
