Where the Filter Goes and What You Need

Samsung refrigerator filters sit in one of two places: inside the fridge compartment (usually in the upper right corner behind a small panel) or underneath the fridge in the base grille. Check your model's location before you start—if you install in the wrong spot, water won't flow through the filter at all.

You will need the replacement filter cartridge itself (the model number is printed on your current filter or in your owner's manual), a small flathead screwdriver or coin, and a cup or bowl to catch water that drains when you remove the old filter. That's it. The whole job takes about five minutes.

Key Takeaways

  • Samsung filters are located either inside the fridge compartment or in the base grille underneath—check your manual or current filter to find yours.
  • Turn off the water supply to your refrigerator before removing the old filter to prevent water from spraying out.
  • Twist the old filter counterclockwise by hand or with a coin until it stops, then pull it straight out and catch the water that drains.
  • Insert the new filter straight in and twist clockwise by hand until you feel it click or seat firmly—do not over-tighten.
  • Run water through the dispenser for 30 seconds after installation to flush air and set up the filter.

Turning Off the Water Supply

Before you touch the old filter, locate the water shut-off valve behind your refrigerator. It is usually a small plastic knob or lever on the copper or plastic water line running into the back of the fridge. Turn it clockwise (or flip the lever to the off position) until it stops. You should feel resistance—do not force it.

If you cannot find the valve or it will not turn, locate the main water shut-off for your house (usually in a basement, crawl space, or utility closet) and turn that off instead. This prevents water from spraying when you pull out the old filter. Test that the water is off by pressing the water dispenser button on the fridge door—nothing should come out.

Removing the Old Filter

Place your cup or bowl underneath the filter location to catch water. If the filter is inside the fridge, you may need to remove a small plastic panel or cover first—push or twist it gently to release. If the filter is in the base grille, you can access it directly from the front.

Grip the filter cartridge with your hand and twist it counterclockwise. If it is stuck, use a coin (a quarter works well) to grip the flat edge and turn it. Keep turning until you feel it stop—usually a quarter turn or less. Pull the filter straight out toward you. Water will drip, so keep your bowl underneath. Wipe the connection point with a clean cloth or paper towel to remove any debris or mineral buildup.

Installing the New Filter

Remove the new filter from its packaging. Some filters come with a protective cap on the inlet—if yours does, twist or pull it off and discard it. Do not remove any other seals or gaskets; those stay on the filter.

Align the filter cartridge with the opening and push it straight in until you feel it seat. The filter should go in smoothly—if you meet hard resistance, pull it out and check that you are inserting it in the correct direction. Once it is seated, twist it clockwise by hand until it stops. You will feel it click or lock into place. Stop when you feel that resistance—over-tightening can crack the filter or damage the connection.

Turning Water Back On and Flushing the Filter

Turn the water shut-off valve counterclockwise (or flip the lever back to on). If you turned off the main house valve, turn that back on. Wait 10 seconds for water pressure to stabilize in the line.

Press the water dispenser button on your fridge door and let water run into a cup for about 30 seconds. The first water may look cloudy or gray—that is air and activated carbon dust from the new filter, and it is normal. After 30 seconds, the water should run clear. If it stays cloudy after a full minute, run it for another 30 seconds. You can now use the water and ice normally.

Common Mistakes to Avoid

The most common error is forgetting to turn off the water supply first. When you pull out the old filter without shutting off the valve, water sprays out and can damage your kitchen floor or cabinets. Always shut off the valve before you start.

The second mistake is installing the filter backward or in the wrong location. Check your owner's manual or the label on your current filter to confirm the location. If water does not come out of the dispenser after installation, the filter is likely in the wrong spot or inserted backward—remove it and try again.

Over-tightening the new filter is also common. You only need to turn it until you feel it click or seat firmly. Forcing it further can strip the threads or crack the filter housing, which will cause leaks later.

When to Replace Your Filter

Samsung refrigerators typically display a filter status light on the control panel or door. When the light turns red or orange, or when your owner's manual says it is time (usually every six months for standard use), replace the filter. Do not wait until water stops flowing—a clogged filter reduces water pressure and can damage the dispenser valve.

If you have very hard water or use the dispenser frequently, you may need to replace the filter more often than six months. If you notice the water tastes off, smells like chlorine, or flows slowly, replace the filter even if the light has not changed color yet.

Frequently Asked Questions

What if water leaks after I install the new filter?

Turn off the water supply when ready and check that the filter is twisted all the way clockwise until it clicks. If it is seated correctly and still leaks, remove it and inspect the connection point for cracks or debris. Wipe it clean and reinstall the filter. If leaking continues, the filter housing may be damaged and you should contact Samsung service.

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

Yes, many third-party filters fit Samsung refrigerators and meet NSF standards for water filtration. Check the model number on the packaging to confirm it is compatible with your fridge model. Installation is identical—the filter twists in the same way regardless of brand.

Why is my water cloudy after I install a new filter?

New filters release activated carbon dust when water first flows through them. Run water for 30 to 60 seconds after installation to flush this out. If water stays cloudy after a full minute, run it for another minute. Cloudiness that persists after several minutes may indicate the filter is installed backward or the wrong filter is in use.

Do I need to turn off the ice maker before replacing the filter?

No, you do not need to turn off the ice maker. However, turning off the water supply will stop ice production temporarily. Once you turn the water back on and flush the filter, the ice maker will resume making ice automatically.

What do I do with the old filter?

Most communities accept used water filters in regular trash or recycling. Some retailers that sell Samsung filters (like Best Buy or Lowe's) accept old filters for recycling. Check your local waste management guidelines or call your city to confirm. Do not pour the old filter down the drain.
