Sub Zero 4204490 Water Filter & 7042798 Air Cartridge Combo Pack

Together, they give your Sub-Zero refrigerator cleaner water and fresher air with one convenient replacement pack.

Specifications

Fresher Taste, Right Away

The Sub Zero 4204490 water filter helps reduce chlorine, sediment, unpleasant tastes, and odors before they reach your glass. That means the water from your dispenser can taste cleaner and fresher with every pour.

Cleaner, Better-Tasting Ice

The water going into your ice maker matters just as much as the water you drink. By filtering unwanted particles and tastes before freezing, the 4204490 helps your ice stay clean and fresh for everyday drinks.

A Fresher Refrigerator Interior

The 7042798 air purification cartridge helps reduce food odors and ethylene gas inside compatible Sub-Zero refrigerators. It continuously helps keep the air fresher, which can be especially useful when your refrigerator is filled with foods that naturally produce strong smells.

Two Replacements in One Pack

This Sub Zero water filter and air cartridge combo gives you two important refrigerator replacements in one package. Instead of ordering the water filter and air purification cartridge separately, you can replace both as part of the same maintenance routine.

Simple, Tool-Free Replacement

The 4204490 water filter uses a twist-lock, quarter-turn installation, so you can replace it without special tools. The 7042798 air cartridge also installs directly into its compatible housing, making routine filter replacement simple.

Built for Everyday Sub-Zero Use

A refrigerator does more than keep food cold. Its water system and internal air filtration system work every day, so keeping both filters fresh can help maintain the experience your Sub-Zero refrigerator was designed to provide.

The 4204490 water filter is rated for up to 750 gallons, while the 7042798 air cartridge is designed for long-term use in compatible Sub-Zero systems. For the best fit, check your refrigerator's existing filter numbers before ordering to confirm that it uses 4204490 and 7042798.
