Sub-Zero Refrigerator Filter Replacement Combo – 4204490 Water Filter & 7007067 Air Cartridge

Looking for a Sub-Zero refrigerator water and air filter replacement combo? This two-component set includes the 4204490 twist-in water filter and the 7007067 air purification cartridge for compatible Sub-Zero refrigeration systems. The water filter helps reduce chlorine taste and odor while filtering particulates, and the air cartridge works with the refrigerator's designated air purification system to help manage ethylene gas and odors. Ordering both components together can make filter maintenance more convenient when both systems require attention. Because Sub-Zero has designated 7042798 as the direct replacement for 7007067, it is important to verify the cartridge supplied with your order and confirm the required part numbers for your refrigerator before purchasing.

Special Features

Convenient Water and Air Filter Replacement

The Sub-Zero 4204490 and 7007067 combo pack brings two replacement components together in one purchase. It is a practical option for customers who prefer to plan refrigerator maintenance and order both components at the same time.

Helps Improve Water Taste

The 4204490 water filter is designed to reduce chlorine taste and odor and filter particulates. Additional contaminant-reduction claims should be based on the manufacturer's published performance data for this exact filter.

Supports Refrigerator Air Purification

The 7007067 cartridge is associated with Sub-Zero's built-in air purification system, which helps manage ethylene gas and odors in compatible refrigerators. It is an air purification component, not a drinking-water filter.

Clear Replacement Part Number Information

Sub-Zero lists 7042798 as the direct replacement for the previous air cartridge number 7007067. Check the existing cartridge and the product supplied by your retailer to ensure the correct replacement is selected for your appliance.

Practical Maintenance Planning

Keep track of your filter replacement dates and follow the refrigerator's indicators and use and care guide. Replace each component according to its own maintenance instructions, as the water and air filtration systems have separate functions.
