Replace the filter by turning off the water supply, locating the filter cartridge under the sink or inside the fridge, twisting it counterclockwise, and screwing in a new one

Most Samsung refrigerators and water dispensers hold the filter in one of two places: inside the fridge behind a panel, or under the sink in a separate housing unit. The replacement itself takes about five minutes and requires no tools beyond your hands. You do not need to call a technician — the cartridge is designed to come out and go back in by hand.

The hardest part is usually finding the right replacement filter for your model. Samsung filters are model-specific, and buying the wrong one wastes money and may not fit. Before you start, locate your refrigerator or dispenser model number and confirm which filter type it uses.

Key Takeaways

  • Samsung filters sit either inside the refrigerator (usually behind the bottom grille or in the upper right corner) or under the sink in a separate housing.
  • Turn off the water supply before removing the old filter to avoid water spilling onto your floor or into cabinets.
  • Replacement filters are model-specific — check your manual or the existing filter itself to find the correct part number before ordering.
  • After installing the new filter, run water through it for 3 to 5 minutes to flush out carbon dust and air pockets before drinking.

Locate your filter and find the model number

Open your refrigerator and look for a cylindrical cartridge. On most Samsung fridges, it sits in the upper right corner behind a removable panel, or at the bottom behind the grille. Some models keep it in the door. If you do not see it inside the fridge, the filter is under your sink in a separate housing unit connected to the water line.

Once you find it, look at the cartridge itself or check your owner's manual for the model number. The number usually starts with "DA" or "HAF" and appears on a label on the filter. Write this down or take a photo — you will need it to order the replacement. Do not guess or buy a generic filter; Samsung filters are not interchangeable between models.

Turn off the water supply before you start

Locate the water shut-off valve under your sink or behind the refrigerator. Turn it clockwise until it stops. If you cannot find a dedicated valve, you may need to turn off the main water supply to your house, though this is rare for refrigerator filters.

Once the water is off, open a faucet or the refrigerator's water dispenser to release any pressure in the line. This step prevents water from spraying out when you remove the old filter. If you skip it, expect a small mess.

Remove the old filter cartridge

If the filter is inside the fridge, open the door and locate the cartridge. Most models have a release button or a twist-lock mechanism. Press the button or turn the cartridge counterclockwise by hand until it comes free. Some filters require a quarter-turn; others need a full rotation. Pull straight out once it loosens.

If the filter is under the sink, you will see a housing unit (usually white or clear plastic) connected to the water line. Turn the housing counterclockwise by hand — it should unscrew without tools. Once it comes free, the old cartridge will either fall out or remain inside the housing. Remove it and set it aside.

Install the new filter and run water through it

Take the new filter out of its packaging. Some filters come with a protective cap or plastic wrapper — remove these before installation. If the filter has a rubber gasket or O-ring, make sure it is seated properly and not twisted.

For filters inside the fridge, insert the new cartridge into the slot and turn it clockwise until it clicks or stops. Do not force it — it should seat smoothly. For under-sink filters, screw the housing back onto the line by hand, turning clockwise until snug. Do not over-tighten; hand-tight is enough.

Turn the water supply back on. Open the refrigerator's water dispenser or the faucet connected to the filter and let water run for 3 to 5 minutes. This flushes out carbon dust and air pockets from the new filter. The water may look slightly gray or cloudy at first — this is normal and will clear.

When to replace your filter and what to watch for

Samsung recommends replacing the filter every 6 months, though this depends on your water quality and how much water you use. If your water tastes off, the dispenser slows down, or the filter light on your fridge turns red or orange, it is time for a new one.

Some Samsung refrigerators have a filter indicator light that turns on automatically. If yours does, press and hold the reset button (usually on the filter housing or inside the fridge) for 3 seconds after installing the new filter. The light will turn off and restart its 6-month countdown.

Where to buy replacement filters and what they cost

Samsung replacement filters are sold at most appliance retailers, big-box stores, and online marketplaces. Prices range depending on the model, but most cost between $30 and $60. Buying directly from Samsung or from a certified retailer ensures you get a genuine filter, not a counterfeit.

Some people buy third-party filters that claim to fit Samsung models. These are usually cheaper but may not filter as effectively or fit as snugly. If you choose a third-party filter, check the reviews for your specific model number first. A poor fit can cause leaks under the sink or inside the fridge.

Frequently Asked Questions

What happens if I install the filter backwards?

The filter will not seat properly and water will leak around the edges. If water drips when you turn on the dispenser, remove the filter, check that the rubber gasket is in place, and reinstall it. Make sure the arrow or "flow" marking on the filter (if present) points in the direction of water flow.

Can I use a generic water filter instead of a Samsung filter?

Generic filters may fit some Samsung models, but they often do not filter as well and may not seal correctly. Samsung filters are designed for your specific model's housing and water pressure. Using the wrong filter can result in leaks or unfiltered water reaching your glass.

Why is my water still cloudy after I installed the new filter?

Run water for another 2 to 3 minutes. New filters contain carbon dust that takes time to flush out. If the water stays cloudy after 10 minutes, the filter may be installed backwards or the gasket may not be seated. Remove it, check the seal, and reinstall.

Do I need to turn off the water supply to replace an under-sink filter?

Yes. Even though the pressure is low, turning off the supply prevents water from dripping onto your cabinets and floor while you work. It also makes the job cleaner and faster.

How do I reset the filter light on my Samsung refrigerator?

Most models have a reset button on the filter housing itself or inside the fridge near the filter. Press and hold it for 3 seconds until the light turns off. Check your manual if you cannot find the button — some older models use a different reset method.
