How Often Should You Replace Your Refrigerator Water Filter?

Why refrigerator water filters need replacement

Refrigerator water filters use activated carbon to reduce contaminants and impurities from your water supply. Over time, the carbon becomes saturated and the filter can no longer trap particles effectively.

A worn-out filter can lead to reduced water flow, an unusual taste or smell in your water and ice, and in some cases can cause the water dispenser or ice maker to stop working properly.

Signs your refrigerator water filter needs replacement

• Water flow from the dispenser is noticeably slower
• Water or ice has an unusual taste or odor
• Ice cubes are smaller than usual or look cloudy
• The filter indicator light on the refrigerator is on
• It has been more than 6 months since the last change

General replacement schedule

Most refrigerator manufacturers recommend replacing the water filter every 6 months. However, the actual timeline depends on your water quality and how much water you use. Homes with harder water or higher sediment levels may need more frequent changes.

Many modern refrigerators have a filter indicator light that turns yellow or red when it’s time to replace the filter.

Basic steps to replace a refrigerator water filter

1. Locate the filter — it’s usually inside the refrigerator (upper right corner or base grille area, depending on the model)
2. Turn or push to release the old filter
3. Remove the cap from the old filter and transfer it to the new one (if applicable)
4. Insert the new filter and turn or push until it locks
5. Run 2–3 gallons of water through the dispenser to flush the new filter
6. Reset the filter indicator light (check your owner’s manual for instructions)

Brand-specific notes

Filter location and replacement steps can vary by brand and model. Here are some general notes:

• Whirlpool / KitchenAid / Maytag — Many models use filters located in the upper right corner inside the refrigerator or in the base grille.
• GE — Many GE models place the filter inside the refrigerator, often in the back upper area or in a cartridge holder. Some newer models use a twist-and-lock design.
• Samsung — Filter locations vary, but many Samsung models have the filter inside the refrigerator (upper right) or integrated into the water pitcher compartment.
• LG — Many LG models place the filter inside the refrigerator, often in the upper left area. Some models use a pull-out cartridge.
• Frigidaire / Electrolux — Many models use a filter located inside the refrigerator or at the top of the fresh food section.

Always check your owner’s manual or the manufacturer’s website for the correct filter model number for your specific refrigerator.

OEM vs generic filters

OEM (Original Equipment Manufacturer) filters are made by or for the refrigerator brand and are designed to fit and perform exactly as intended. Generic or aftermarket filters are usually less expensive but may vary in quality, filtration performance, and fit.

Using an OEM filter is generally recommended for the best results, especially if your refrigerator is still under warranty.

What if the filter gets stuck?

If the filter won’t release, try the following:

• Make sure you’re turning or pushing in the correct direction (check your manual)
• Grip the filter firmly — some filters require a strong quarter-turn before they release
• If the filter housing is cracked, swollen, or damaged, do not force it

A stuck filter can sometimes be caused by water pressure buildup or a damaged housing. If you can’t remove it safely, a technician can help without damaging the housing.

What if the refrigerator leaks after filter replacement?

A small amount of water dripping after a filter change is normal — especially if the filter wasn’t fully seated. Check that the filter is properly locked in place.

If leaking continues, the filter housing, O-ring, or water line connection may need attention. Persistent leaks after a filter change should be inspected by a technician.
