How to Replace Your Refrigerator Water Filter

How often to change it

Plan on a new filter about every six months. Many refrigerators light up a filter indicator when it's time, but cloudy water, an off taste or slower dispenser flow are also signs a filter is overdue. An old filter can become saturated and let more contaminants through, even when the water still looks clean.

Step 1: Find your filter type

Check the part number printed on your current filter, or look up the approved filter for your refrigerator's model number (usually on a label inside the fresh-food compartment). Filters generally sit in one of two places: inside the fridge, often in the upper right corner, or behind the base grille at the bottom front.

Step 2: Remove the old filter

• Interior filters: open the filter cover, then pull, twist or turn the cartridge (usually to the left) to release it, depending on your model.
• Base-grille filters: press the eject button. If it sticks, push the filter in first, then press and hold the button firmly.
• You typically don't need to shut off the water supply — but check your owner's manual to be sure.

Step 3: Install the new filter

• Unwrap the new filter and remove the protective caps from the O-rings, making sure the O-rings stay in place — a missing or worn O-ring is a common cause of leaks.
• Line up the arrow or grooves as shown on the housing, then push in (and turn, if your model requires it) until the filter locks.
• Never force it. If it won't slide or lock, pull it out, realign it and try again — over-tightening can distort the seal.
• Close the filter door until it snaps shut. If it won't close, the filter isn't fully seated.

Step 4: Flush, check and reset

• Run water through the dispenser to flush out trapped air and carbon dust — many manufacturers recommend about four gallons.
• Check the filter housing and dispenser area for drips over the next few hours.
• Reset the filter indicator light. The button is often on the dispenser panel or an interior control panel; press and hold for a few seconds until it beeps or changes.
