Find your filter location and model number first

Samsung refrigerators hold their water filters in one of three places: inside the fridge compartment (usually upper right corner or back wall), inside the freezer, or underneath the unit behind a kick plate. Open both compartments and look for a cylindrical cartridge about the size of a soda can, often white or blue. If you do not see it inside, crouch down and check under the front of the fridge — you may need to remove a plastic panel by hand or with a flathead screwdriver.

Write down your fridge's model number before you buy a replacement filter. The model number is on a sticker inside the fridge, usually on the back wall or on the side wall near the top. Samsung filters are model-specific: a filter for an RF28 will not fit an RS25. You can search your model number on Samsung's website or call their customer service line to confirm which filter you need, or take a photo of your current filter and show it to a salesperson at an appliance store.

Key Takeaways

  • Samsung fridge filters sit in three possible locations: upper right inside the fridge, inside the freezer, or under the unit behind the kick plate.
  • Write down your model number before buying a replacement, because filters are not interchangeable between different Samsung models.
  • Most filters twist counterclockwise to remove and clockwise to install, but some models use a push-and-release button instead.
  • After installing a new filter, run water through the dispenser for 30 seconds to flush out air and carbon dust.
  • Replace your filter every six months or when water flow slows, whichever comes first.

Remove the old filter by twisting or pressing

If your filter is inside the fridge or freezer, grip it firmly with both hands and turn it counterclockwise — think of it like unscrewing a jar lid. Turn slowly and steadily until it stops, then pull it straight out toward you. Some models have a release button on the filter housing instead: press the button and the filter will pop out slightly, then pull it the rest of the way by hand.

If your filter is under the unit, you will need to remove the kick plate first. Grip the bottom edge of the plastic panel and pull it toward you — it usually snaps off without tools. The filter cartridge will be visible in a horizontal housing. Twist it counterclockwise or press the release button, depending on your model, and slide it out. Do not force it; if it does not turn smoothly, you may be turning the wrong direction.

Water may drip when you remove the old filter. Place a towel or shallow pan underneath before you start. If water continues to drip after you have removed the filter, this is normal — the system is depressurizing. Let it drain for a few seconds, then wipe up any spill.

Install the new filter and reset the indicator light

Before you insert the new filter, check the rubber gasket (the ring of rubber around the end of the cartridge) to make sure it is clean and seated properly. If it is cracked or loose, the filter will not seal and you will have leaks. Slide the new filter into the housing and turn it clockwise until it stops — you should feel it click or seat firmly. Do not over-tighten; hand-tight is enough.

After the filter is installed, you need to reset the filter indicator light on your fridge's display panel. The steps vary by model. On most Samsung fridges, you hold down the "Filter" or "Reset" button on the control panel for three seconds until the light goes out or changes color. Some models require you to press a button on the filter housing itself. Check your owner's manual or search "[your model number] reset filter light" online to find the exact steps for your fridge.

Flush the system to remove air and carbon dust

New filters contain loose carbon particles and air pockets that can affect water taste and flow. Turn on the water dispenser and let water run into a cup or sink for 30 seconds without stopping. The water may look cloudy or taste slightly off — this is normal and will clear after flushing. Repeat this once more if the water still looks cloudy.

If you have an ice maker, run a full cycle to clear the line as well. Press the ice dispenser button and let ice fall into a bucket until one full batch has been made and dispensed. Throw away this first batch of ice, as it may contain carbon dust or air bubbles.

Troubleshoot slow water flow or leaks

If water comes out slowly after you install a new filter, the filter may not be seated correctly. Turn off the water dispenser, remove the filter, and check that the rubber gasket is clean and not twisted. Reinstall it and make sure you hear or feel it click into place. Run water again for 30 seconds to see if flow improves.

If water leaks from the connection where the filter meets the housing, the gasket may be damaged or the filter may not be twisted in far enough. Remove the filter, inspect the gasket for cracks or debris, and clean both the gasket and the housing opening with a dry cloth. Reinstall the filter, turning it clockwise until you feel firm resistance. If leaking continues, the filter cartridge itself may be defective — contact Samsung or return it to the store where you bought it.

If water leaks from under the fridge after you install a filter, the issue is usually in the line connection under the unit, not the filter itself. Turn off the water supply to the fridge (usually a valve behind or under the unit), remove the kick plate, and check that the filter housing connection is tight. If you see water pooling, you may need a professional to inspect the water line.

Know when to replace your filter

Samsung recommends replacing your water filter every six months under normal use. If you have hard water or use the dispenser heavily, you may need to replace it more often — every three to four months. The filter indicator light on your display will turn on or change color when the filter is due, but do not wait for the light if water flow has already slowed.

You can buy Samsung filters at appliance stores, big-box retailers like Lowe's and Home Depot, and online through Amazon or Samsung's official website. Prices range depending on the model, but most genuine Samsung filters cost between $30 and $60. Third-party filters are cheaper but may not fit as securely or filter as effectively — stick with Samsung brand filters or filters certified to fit your specific model.

Frequently Asked Questions

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

Third-party filters designed for your model may work, but Samsung filters are engineered to fit your fridge's housing and water pressure system precisely. A loose-fitting filter can leak or allow unfiltered water through. If you choose a third-party option, buy one certified for your exact model number and test it for leaks before relying on it long-term.

What do I do if I cannot find the filter location in my fridge?

Check your owner's manual — it will have a diagram showing the exact location for your model. If you do not have the manual, search your model number plus "water filter location" online, or call Samsung customer service at 1-800-726-7864. They can walk you through finding it over the phone.

Is it normal for water to taste different after I install a new filter?

Yes, for the first few uses. New filters release small amounts of carbon dust and air, which can affect taste. Run water through the dispenser for 30 seconds and discard it. If the taste does not improve after two or three flushes, the filter may be defective or installed incorrectly.

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

No, you do not need to turn off the main water supply. However, some water will drip when you remove the old filter, so have a towel ready. If you see water pooling under the fridge after installation, then turn off the water supply valve (usually located behind or under the unit) and check the connection.

How long does a Samsung water filter actually last?

Six months is Samsung's standard recommendation, but actual lifespan depends on your water quality and how much you use the dispenser. Hard water, high sediment, or heavy use can reduce filter life to three or four months. If water flow slows noticeably before six months, replace the filter early.
