What this filter does
A refrigerator filter is built to handle a set amount of water, known as its rated capacity. It serves the water dispenser and ice maker in your fridge door.
Over time, the filter reaches its limit as water passes through. Typical change intervals serve as rough guidance, with fridge filters typically changed about every 6 months. You should always follow the interval given in your manual or on the product page.

How to confirm a replacement matches
Fit is matched by model and part number. You can 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 located inside a fridge on a side wall, on the side or front of a water system, or right on the old filter itself. Check these areas carefully to make sure your numbers align.
Signs of filter wear and safe replacement
A filter should be replaced sooner than the usual interval if water flow slows down or if the filter indicator light turns on. Many fridge filter lights track elapsed time or water volume used rather than testing the water directly.
When installing a new filter, always complete the recommended flush cycle before drinking the water. Follow the specific flush instructions printed on the packaging to clear out air and prepare the filter for daily use.
Read your old filter
- Locate the printed label directly on your old filter housing.
- Check that the label reads part number 261836.
- Find your refrigerator model number on the side wall inside the fridge compartment.
- Match the number from your old filter or fridge model against the listing to confirm a correct fit.
