Sub-Zero 4204490 Refrigerator Water Filter

The Sub-Zero 4204490 Refrigerator Water Filter is a replacement cartridge for compatible Sub-Zero refrigerators with a matching water filtration system. It filters the water supplied to your dispenser and ice maker, helping reduce chlorine, lead, sediment, and other unwanted impurities that can affect water taste and quality. With a simple twist-and-lock design, replacing the cartridge is a straightforward part of regular refrigerator maintenance.

Specifications

Cleaner-Tasting Refrigerator Water

The 4204490 filter helps reduce chlorine and other impurities that can affect the taste of water from your refrigerator dispenser. A fresh cartridge gives your everyday drinking water a cleaner, more pleasant taste without changing how you use the dispenser.

Better Water for Your Ice

Your refrigerator's ice maker uses the same filtered water supply. By reducing sediment and unwanted tastes before the water reaches the ice maker, the Sub Zero 4204490 water filter helps keep your ice cleaner and fresher for everyday drinks.

Helps Reduce Sediment

Sediment can enter the refrigerator water system along with your household water supply. The 4204490 is designed to reduce sediment and other unwanted particles before they reach the dispenser and ice maker, helping maintain cleaner water throughout the system.

Easy Twist-and-Lock Replacement

Changing the filter does not require a plumber or special equipment. The 4204490 uses a twist-and-lock connection, so the old cartridge can be removed and the new one secured directly into the compatible filter housing.

Replace It on Schedule

The product page lists a service life of up to 6 months or 500 gallons, whichever comes first. Actual replacement timing can vary with household water consumption and water quality, so your refrigerator's maintenance recommendations should also be taken into account.

Built for Compatible Sub-Zero Refrigerators

The 4204490 is designed for specific Sub-Zero refrigerator filtration systems rather than being a universal refrigerator filter. Before ordering, check the model information for your refrigerator or compare the part number on your existing cartridge to make sure the 4204490 is the correct replacement.

If your refrigerator uses a different filter number, such as 4290510 or 9030868, use the corresponding cross-reference product page rather than assuming every Sub-Zero water filter is interchangeable. This keeps the replacement matched to the correct filtration housing.
