Having fresh, clean drinking water from your refrigerator is one of the best modern conveniences in any home.
But many homeowners don’t realize how important the refrigerator water filter is to keeping that water pure and safe.
Over time, your fridge’s water filter collects impurities from your water supply—so replacing it regularly is key to maintaining your appliance and your family’s health.
How Refrigerator Water Filters Work to Improve Water Quality
Refrigerator water filters rely on activated carbon and other filtration technologies to trap contaminants like chlorine, sediment, and harmful particles.
This filtration process improves both taste and odor while extending the life of your ice maker and internal water lines.
Essentially, your refrigerator’s water filter works as the first line of defense against poor water quality inside your kitchen.
How Often Should You Replace a Refrigerator Water Filter?
Most refrigerator manufacturers recommend replacing the water filter every six months. However, water usage, water quality, and brand differences can affect this schedule.
Factors That Impact Filter Replacement Frequency
-
Local water quality: If your area has hard water, high mineral content, or contaminants, you may need to replace your filter more often.
-
Appliance usage: The more you use the ice and water dispenser, the faster the filter will clog.
-
Brand and model: Some refrigerator filters are designed for higher capacity (measured in gallons), while others need more frequent attention.
If your fridge has a filter change indicator light, use it as a guide—but always refer to your owner’s manual for the best advice.
Signs You Need to Change Your Refrigerator Water Filter
Even if it hasn’t been six months, certain changes in your refrigerator’s performance can tell you it’s time for a replacement:
-
Noticeably slower water flow from the dispenser
-
Water or ice that tastes or smells off
-
Cloudy or discolored ice cubes
-
A lit or blinking refrigerator filter light
Any of these signs means your filter can no longer remove impurities effectively.
Choosing the Right Replacement Water Filter for Your Fridge
Identifying the Correct Model
Check your refrigerator’s user manual or look inside the fridge for its model number. You’ll typically find it near the crisper drawers, on the inner wall, or on the appliance’s back panel.
OEM vs. Compatible Refrigerator Filters
You can choose between Original Equipment Manufacturer (OEM) filters, which are made by your appliance’s brand, or compatible filters from third-party vendors.
Whichever you choose, make sure the filter is NSF-certified to ensure it meets safety and performance standards.
Step-by-Step Guide: How to Replace a Refrigerator Water Filter
-
Locate the filter compartment—it’s usually in the grille at the bottom, inside corner, or rear panel.
-
If needed, shut off the refrigerator water supply.
-
Remove the old filter and insert the new one, following the arrows or alignment markings.
-
Once installed, flush at least two gallons of water through the new filter to remove air and loose carbon particles.
-
Reset your filter replacement indicator light.
This quick process can be done in just a few minutes and greatly improves your water’s quality.
Frequently Asked Questions About Refrigerator Water Filters
Do You Really Need to Replace Your Filter Every Six Months?
Yes. Bacteria and contaminants can build up inside older filters, reducing water quality and possibly affecting appliance performance.
What Happens If You Don’t Replace the Filter?
Ignoring filter maintenance leads to poor-tasting water, reduced pressure, and potential clogs in your refrigerator’s water system.
Can You Clean and Reuse an Old Filter?
No. Refrigerator water filters are designed for single use. Once the carbon and filtration materials are saturated, cleaning them won’t restore their effectiveness.
