What the EDR2RXD1 Filter Does

This Refrigerator water filter is used to filter water for your fridge door dispenser and ice maker. A filter is built to handle a set amount of water, its rated capacity.

Over time, the filter collects material from the water line. When the filter reaches its capacity, water flow may slow down. Replacing the cartridge keeps clean water moving to your dispenser and ice maker.

How to Confirm a Match

Fit is matched by model: search the model of your system, the number on your old filter, or your fridge model. You can check the label on your existing cartridge to see if it shows part number EDR2RXD1.

Many models list their model number on a label: on the side or front of a water system, on the old filter, or inside a fridge on a side wall. Compare the markings directly to verify a match before you install a new part.

When to Replace and How to Install Safely

Typical change intervals are rough guidance: fridge filters about every 6 months. The interval on the product page and in the manual always wins. Change it sooner if water flow slows or the filter light comes on.

Many fridge and RO filter lights track time or water used. They do not test the water. When it is time to install a replacement, remove the old unit, seat the new cartridge firmly in place, and follow the flush steps on the box or product page before drinking the water.

Read your old filter

  1. Locate the existing water filter inside your refrigerator or water compartment.
  2. Remove the filter carefully and look at the printed product label.
  3. Check for the part number EDR2RXD1 printed on the label.
  4. If the label is missing, check the model label inside your fridge on a side wall to look up your fridge model.

When to call a pro

If you are not sure about plumbing work, or if you run into leaks that do not stop, hire a licensed plumber.
