Sub-Zero 7042798: Fresher Food, Cleaner Air

The Sub-Zero 7042798 is an air filter cartridge for your Sub-Zero refrigerator. It replaces the older part number 7007067 and fits the same models. Built on NASA-based technology, this cartridge scrubs the air inside your fridge every 20 minutes, so your food stays fresh longer.

What Does the Sub-Zero 7042798 Remove From the Air?

This cartridge reduces or removes:

• Mold spores
• Viruses and bacteria
• Ethylene gas, the compound that speeds up ripening and spoilage
• Odors from strong foods like onions, garlic, and fish

Because it targets contaminants too small for regular filters, your fruits and vegetables stay fresh longer, and your fridge stays free of mixed food smells.

How Long Does It Last?

This cartridge is designed to last up to one year. After that, replace it to keep your air purification system working at full strength.

What Refrigerators Does It Fit?

This cartridge fits every Sub-Zero refrigerator, freezer, and wine storage unit with a built-in air purification system, including Classic, Designer, and Pro series models. It replaces old part number 7007067 — the two parts are the same unit and fit the same units.

Easy to Install

The cartridge fits into the air purification housing inside your fridge. No tools needed. Just remove the old cartridge and place the new one in its spot.

Please note: During shipping, some carbon dust from inside the cartridge may settle on its outer surface. This is normal and won't affect performance. Just wipe it clean with a paper towel before you install it.
