Locate Your Filter and Gather What You Need

Most GE refrigerators have the water filter in one of two places: inside the refrigerator compartment (usually in the upper right corner or along the back wall) or underneath the sink cabinet if your model has an external filter system. Open your refrigerator and look for a cylindrical cartridge about the size of a soda can, often white or blue, with a release button or twist mechanism. If you don't see one inside, check under your sink for a filter housing mounted to the cold water line.

Before you start, gather a small bowl or cup to catch water that will drip when you remove the old filter, and have your replacement filter ready. You can find the correct replacement by checking your refrigerator's model number (usually on a sticker inside the fridge or on the back) and looking it up on GE's website or your owner's manual. Common GE filter models include the MWF, MWFA, and GWF series, but your specific model may differ.

Key Takeaways

  • GE refrigerator filters are located either inside the fridge compartment or under the sink, depending on your model.
  • You can identify your filter type by checking your refrigerator's model number against GE's filter compatibility chart.
  • The entire filter change takes about five minutes and requires only the new filter and a small bowl to catch drips.
  • After installing the new filter, run water through the dispenser for 30 seconds to flush air and set up the filter.
  • Most GE filters should be replaced every six months, though this varies based on your water quality and usage.

Remove the Old Filter from Inside the Refrigerator

If your filter is inside the fridge, place your bowl underneath it first to catch any water. Locate the release button or twist mechanism on the filter cartridge. For push-button models, press the button firmly and the filter will pop out slightly—pull it straight toward you to remove it completely. For twist models, turn the filter counterclockwise (to the left) about a quarter turn until it stops, then pull it straight out.

Some water will drip into your bowl, which is normal. If water continues to drip after you've removed the filter, don't worry—this is the refrigerator's water line releasing pressure. Let it drain for a few seconds, then wipe the area dry with a paper towel before installing the new filter.

Remove an Under-Sink Filter System

If your filter is mounted under the sink, place your bowl under the filter housing to catch water. Most under-sink filters have a release button on the side or a twist mechanism similar to the internal models. Press the button or turn counterclockwise until the cartridge stops, then pull it straight down and out of the housing.

Water will drip from both the cartridge and the housing itself. Let it drain completely into your bowl before proceeding. If water continues to flow from the housing after you've removed the cartridge, turn off the water supply valve (usually a small knob on the cold water line under the sink) by turning it clockwise, then try again.

Install the New Filter Correctly

Before inserting the new filter, check that the rubber gasket (the small ring at the end of the cartridge) is clean and properly seated. If it looks dry, you can lightly wet it with tap water—this helps create a better seal. For internal filters, align the cartridge with the slot and push it straight in until you hear a click or feel it lock into place. For push-button models, the filter will click when fully inserted; for twist models, push in and turn clockwise until it stops (usually a quarter turn).

For under-sink filters, insert the new cartridge into the housing and turn clockwise until it stops. Do not over-tighten—stop as soon as you feel resistance. If you've turned off the water supply, turn it back on now by rotating the valve counterclockwise.

Flush the New Filter Before Using It

After installation, run water through the dispenser for 30 seconds without collecting it. This flushes air out of the new filter and activates the carbon media inside. The water may look slightly cloudy or gray during this time—this is normal and will clear within a few seconds. If you have an ice maker, it will also dispense some ice during this flush; you can discard this ice.

After the 30-second flush, your water and ice should be ready to use normally. Some people notice a slight taste or smell change after installing a new filter; this usually disappears within a day or two as the filter fully activates.

Know When to Replace Your Filter

GE recommends replacing your water filter every six months under normal household use. However, the right timing depends on your water quality and how much water you dispense. If you have hard water or use the dispenser frequently, you may need to replace it more often—every three to four months. If you use it rarely, you might stretch it to nine months.

Most GE filters have a small indicator light on the refrigerator's display panel that will turn red or orange when the filter is due for replacement. Don't ignore this light—a clogged filter reduces water pressure and allows bacteria to grow. If you notice the water dispenser is slower than usual or the ice maker is producing less ice, the filter is likely clogged and should be replaced when ready, even if the indicator hasn't lit up yet.

Troubleshoot Common Problems

If water leaks from the filter area after installation, the cartridge may not be fully seated. Remove it and try again, making sure you push it all the way in until you hear the click or feel the stop point. Also check that the rubber gasket is clean and not damaged. If the gasket looks cracked or worn, you may need a replacement gasket kit (sold separately by GE).

If the water dispenser has very low pressure after you install a new filter, you may have trapped air in the line. Run the dispenser for a full minute without stopping to push the air through. If pressure is still low after that, check that you turned the under-sink water supply valve all the way back on (if your model has one). If you still have problems, contact GE customer service with your model number—there may be an issue with the water line itself.

Frequently Asked Questions

Can I use a third-party filter instead of a GE filter?

You can, but GE does not recommend it. Third-party filters may not fit properly, may not filter as effectively, and could damage your refrigerator's water system. Stick with GE-branded filters or filters certified as compatible with your specific model to avoid leaks and poor water quality.

What do I do with the old filter?

Most communities accept water filters in regular recycling or at special e-waste collection events. Some retailers that sell replacement filters, like Home Depot or Lowe's, also accept old filters for recycling. Do not throw it in the trash if your area has a recycling program.

Why is my water cloudy after I change the filter?

Cloudiness is usually just air bubbles in the water line and will clear within a few seconds. If it persists for more than a minute or two, run the dispenser for another 30 seconds. If the water stays cloudy or discolored after that, the filter may be defective and should be replaced.

Do I need to turn off the water supply before changing the filter?

No, you don't need to for internal filters—just have a bowl ready to catch drips. For under-sink filters, you only need to turn off the water supply if water continues to drip from the housing after you remove the cartridge. Most of the time, the pressure releases on its own.

How do I know which filter my GE refrigerator uses?

Check your owner's manual or look up your refrigerator's model number on GE's website. The model number is usually on a sticker inside the fridge or on the back. You can also call GE customer service with your model number and they will tell you the correct filter type.
