A clean refrigerator water filter is the difference between fresh, great-tasting water and water that carries odors, sediment, or contaminants. The good news? Changing your fridge filter is a simple, tool-free job that takes about five minutes. This step-by-step guide walks you through exactly how to do it.
Why Replacing Your Refrigerator Water Filter Matters
Over time, the carbon inside your filter becomes saturated and stops trapping chlorine, lead, sediment, and other impurities. An old filter can also slow your water dispenser and leave cloudy ice. Replacing it on schedule keeps your water safe, your ice clear, and your refrigerator running efficiently. Browse compatible options in our refrigerator water filters collection.
Before You Begin: What You'll Need
In most cases you need nothing but your hands and a replacement filter that matches your refrigerator model. Keep a towel nearby to catch a few drops of water, and have your old filter handy so you can match it to the correct replacement.
Step-by-Step: How to Change a Refrigerator Water Filter
Step 1: Locate Your Filter
Filters are usually found in one of three places: inside the upper-right corner of the fridge compartment, in the bottom front grille, or at the back lower corner. Check your owner's manual if you're unsure.
Step 2: Release the Old Filter
For twist-style filters, turn the filter a quarter-turn counter-clockwise until it releases. For push-button filters, press the eject button and the cartridge will pop out. Pull it straight out gently.
Step 3: Prepare the New Filter
Remove the protective caps from the new filter. Do not run water through it yet. Confirm the model number matches your old filter so you get the correct fit and seal.
Step 4: Insert and Lock the New Filter
Push the new filter into the housing and twist a quarter-turn clockwise (or push until it clicks) until it locks firmly in place. A loose filter is the most common cause of leaks.
Step 5: Flush the System
Run 2 to 4 gallons of water through the dispenser to clear air and carbon dust. The water may sputter at first — that's normal. Once it runs clear and steady, your filter is ready.
Step 6: Reset the Filter Indicator
Press and hold the "Filter Reset" button on your control panel for about three seconds until the light turns from red to green or off. This restarts the replacement countdown.
How Often Should You Replace It?
Most manufacturers recommend replacing your filter every six months, or sooner if you notice reduced flow or a change in taste. Households with hard water or heavy usage may need to replace more often.
Frequently Asked Questions
Do I need to turn off the water before changing the filter?
No. Modern refrigerators have an internal shut-off valve that automatically stops water flow when the filter is removed, so you can swap it without turning off your water supply.
Why is my water cloudy after changing the filter?
Cloudiness is caused by trapped air and is completely harmless. Run a few gallons through the dispenser and it will clear up within a day.
Can I use a non-branded replacement filter?
Yes — high-quality compatible filters are tested to meet the same standards as OEM filters at a lower cost. Just make sure the model number matches. Find your match in our water filter collection or shop by your refrigerator brand.
