Learn how to replace a refrigerator water filter with our simple, step-by-step DIY guide. Keep your drinking water fresh and clean with our easy instructions.
Clean, filtered water is one of the best features of a modern refrigerator, but it’s easy to forget about the filter itself. An old or clogged filter can lead to a drop in water flow, bad-tasting water, and potential health risks. Knowing how to replace a refrigerator water filter is a quick and easy DIY task that can save you a service call and ensure your family has access to the best-tasting, cleanest water possible. This comprehensive guide will walk you through everything you need to know, from understanding when to change the filter to a step-by-step tutorial on the replacement process.
The Importance of Your Refrigerator Water Filter
Your refrigerator’s water filter is designed to remove contaminants from your tap water before it’s dispensed or used to make ice. Common filters use activated carbon to trap impurities like lead, chlorine, bacteria, and other harmful substances. Over time, the filter becomes saturated and less effective, leading to a decline in water quality. Regular replacement is crucial for both taste and health.
Manufacturers typically recommend changing the filter every six months, but this can vary depending on your household’s water usage and the quality of your tap water. If you notice a change in the taste or odor of your water, or if the water flow from the dispenser slows down, it’s a clear sign that you need to replace a refrigerator water filter.
Choosing the Right Replacement Filter
The most important part of this project is making sure you have the correct replacement filter. Not all filters are the same. Your refrigerator is designed to work with a specific type and model number. Using the wrong filter can cause leaks or damage your refrigerator’s water system.
- Check the Owner’s Manual: This is always the best place to start. Your manual will list the exact filter model number.
- Look at the Existing Filter: If you can’t find the manual, the model number is usually printed directly on the filter itself.
- Use the Refrigerator’s Model Number: If all else fails, you can use your refrigerator’s model number to search for the correct filter online or at an appliance parts store.

Locating Your Water Filter
Replace a Refrigerator water filter by location in different spots depending on the brand and model of your appliance. The most common locations include:
- Inside the Refrigerator: Often in the upper right-hand corner or on the ceiling, in a small housing.
- Behind the Refrigerator’s Kickplate: The kickplate is the grill at the bottom front of the refrigerator.
- Inside a Compartment on the Door: Some French door models have the filter located on the inside of the door.
Once you’ve located the filter, the replacement process is very straightforward. You won’t need any special tools for this job.
Step-by-Step Guide: How to Replace a Refrigerator Water Filter
Follow these instructions for a successful, leak-free refrigerator water filter replacement.
- Turn Off the Water Supply: Before you begin, shut off the water supply to the refrigerator. This is usually done by turning a small valve located on the water line behind the appliance or under the kitchen sink.
- Remove the Old Filter: Depending on your model, this step will vary slightly.
- Twist-and-Pull Filters: For these common filters, simply twist the filter counter-clockwise and pull it straight out. A small amount of water may drip out, so have a towel ready.
- Push-and-Release Filters: Some models have a small button or latch you press to release the filter. Push the button and the filter will pop out.
- In-line Filters: These are located on the water supply line behind the refrigerator. You’ll need to remove the clips holding the old filter in place and then disconnect the lines. This is the most complex type of refrigerator water filter replacement, so be sure to consult your manual.
- Install the New Filter:
- Twist-and-Pull Filters: Insert the new filter into the housing and twist it clockwise until it’s secure. You will feel a slight click when it’s properly seated.
- Push-and-Release Filters: Simply push the new filter into the housing until it clicks into place.
- In-line Filters: Push the water lines onto the new filter until they are firmly seated, then re-secure the clips.
- Flush the System: This is a crucial step. After installing the new filter, turn the water supply back on and dispense water from the dispenser for at least five minutes. This will clear any air from the lines and flush out any loose carbon particles from the new filter. The water may appear cloudy or gray at first, but it will clear up after a few minutes.
- Reset the Filter Light: Most refrigerators have a filter-change indicator light that you’ll need to reset. The method for resetting the light varies by brand, but it’s usually done by pressing and holding a button on the display panel for three to five seconds. Consult your manual for the exact instructions for your model.
Troubleshooting Common Replacement Problems
- Water Leaks: If you notice a leak after installation, the new filter may not be properly seated. Remove the filter, check for any damage to the O-rings, and reinstall it, ensuring it’s twisted or pushed in all the way.
- Slow Water Flow: A slow flow after a filter change is usually due to air in the lines. Continue to flush the system by dispensing water for a few more minutes.
- Cloudy Water: This is completely normal and is caused by air and carbon dust from the new filter. It will clear up after you flush the system.

Preventative Maintenance and Best Practices
To avoid future issues, here are some tips to keep your water and ice system running smoothly. Replace a Refrigerator water filter:
- Replace on Schedule: Don’t wait for the indicator light to turn on. Change your filter every six months to ensure consistent water quality. You can even set a calendar reminder to stay on track.
- Buy a Spare: When you buy a new filter, it’s a good idea to purchase a spare so you always have one on hand when it’s time to replace it.
- Clean the Dispenser: Regularly clean the water and ice dispenser with a soft cloth to prevent the build-up of bacteria and mold.
- Keep the Filter Clean: If you have a twist-and-pull filter, occasionally wipe down the outside of the filter housing to keep it free from dust and grime.
