Why Choose Genuine Sub-Zero Filters?

Original OEM Fit and Quality

Both replacement filters are genuine Sub-Zero parts designed for compatible refrigerator systems. Avoid the uncertainty of generic or imitation alternatives.

Better-Tasting Water and Ice

The 4204490 water filter helps reduce chlorine taste and odor, particulate matter, lead, mercury, cysts, and other contaminants specified in the manufacturer's performance data.

Advanced Air Purification

Sub-Zero's air purification system circulates refrigerator air through a specialized cartridge to help reduce ethylene gas and unwanted odors. Reducing ethylene can help slow the ripening process of certain fresh foods.

Convenient Two-Filter Bundle

Purchase your water filter and air purification cartridge together for a simpler refrigerator maintenance routine.

Easy Replacement

Both filters are designed for replacement in compatible Sub-Zero systems. Follow your refrigerator's Use & Care Guide for model-specific installation and filter-life reset instructions.

Product Specifications

Refrigerator Compatibility

This combo is designed for select Sub-Zero refrigerators that use both the 4204490 twist-in water filter and the 7042798 air purification cartridge.

Compatible refrigerator families may include:

• Sub-Zero Classic Built-In (BI) series

• Sub-Zero Classic (CL) series

• Sub-Zero Designer (IC, IT, DET, DEC) series

Important: Not every refrigerator within these families uses both filters. Some older BI models use a different two-prong water filter, and some models do not have an air purification system.

Check your complete refrigerator model number, serial number, and current filter part numbers before ordering.
