What this refrigerator filter does

This cartridge treats the water and ice in your fridge door. A filter is built to handle a set amount of water, which is its rated capacity.

Over time, the cartridge fills as it treats water. Replacing it on schedule keeps water moving properly through your refrigerator door.

How to confirm a matching replacement

Fit is matched by model. Search the model of your system, the number on your old filter, or your fridge model.

Many models list their model number on a label. Check the side or front of a water system, look on the old filter, or inspect the inside side wall of the fridge.

Signs it is time to replace your filter

Typical change intervals are rough guidance. Fridge filters are changed about every 6 months. The interval on the product page and in the manual always wins.

Change the cartridge sooner if water flow slows down or if the filter light comes on. Many fridge filter lights track time or water used. They do not test the water.

Read your old filter

  1. Remove the old filter from the housing inside your refrigerator.
  2. Locate the printed label on the body of the old cartridge.
  3. Check that the label displays part number FPPWFU01.
  4. Check the model label on the inside side wall of your fridge to verify your appliance details.

When to call a pro

If you notice water leaks behind the refrigerator or you are not sure about plumbing work, stop and hire a licensed plumber.
