Genuine Sub-Zero 4204490 refrigerator water filter

The Sub-Zero 4204490 refrigerator water filter is the original twist-in cartridge made by Sub-Zero, in its original Sub-Zero packaging. As a result, it filters the water and ice exactly as Sub-Zero designed.

Sub-Zero 4204490 refrigerator water filter, genuine Sub-Zero

Why replace it every year

Sub-Zero rates the filter for 750 gallons and up to 12 months. In addition, Sub-Zero lists it as meeting NSF/ANSI 42 and 53. A household that uses a lot of water and ice, however, reaches the gallon limit sooner, so the flow from the dispenser slows down when the filter is full.

How to replace the Sub-Zero 4204490 refrigerator water filter

  1. First, find the water filter in your refrigerator. Your Sub-Zero use and care guide shows its position.
  2. Next, turn the old filter counterclockwise and pull it out.
  3. Then insert the new filter and turn it clockwise until it stops.
  4. Finally, run water from the dispenser for a few minutes and reset the filter reminder if your model has one.

Tips after a filter change

Run about two gallons of water through the dispenser after each change, because the first water flushes out air and loose carbon. Also, throw away the first batch of ice. If the water flow is weak afterwards, make sure the filter sits fully in place. Finally, write the install date on the filter or set a phone reminder, so you know when the next change is due.

Questions

Is this a genuine Sub-Zero part? Yes. It is the original Sub-Zero filter in its original box, not a compatible copy.

Do you sell the Sub-Zero air purification cartridge? Yes. Together with this water filter, the Sub-Zero 7042798 is also in a yearly bundle.
