Where to find your Samsung fridge water filter and what type you have

Samsung refrigerators use one of two filter locations: either inside the fridge compartment (usually in the upper right corner behind a small panel) or underneath the fridge in the base grille. Open your fridge door and look for a cylindrical cartridge behind a plastic cover, or crouch down and look for a horizontal filter tucked into the front grille. Your model number, printed on a sticker inside the fridge or on the back wall, tells you which one you have — you can search it on Samsung's website or your manual to confirm before you buy a replacement.

The filter type matters because Samsung makes several cartridge sizes. The most common are the DA29-00003G (older models), DA29-00020B (mid-range), and HAF-CIN (newer models with the filter in the base). Write down your exact model number and filter type before you shop, because buying the wrong cartridge wastes money and leaves you unable to install it.

Key Takeaways

  • Samsung fridge filters sit either inside the fridge compartment or in the base grille, and you must know which before buying a replacement.
  • Turn off the water supply to your fridge before you remove the old filter to avoid water spilling onto your floor.
  • The replacement cartridge twists or slides out depending on your model, and the new one goes in the same way it came out.
  • After installation, run water through the dispenser for 30 seconds to flush air from the line and clear any carbon dust from the new filter.
  • Most Samsung filters need replacement every six months if you use the ice maker and water dispenser regularly, or every 12 months with light use.

Turn off the water supply before you start

Locate the water shut-off valve behind your refrigerator. It is usually a small plastic knob or lever on the copper or plastic line running into the back of the fridge. Turn it clockwise (or flip the lever to the off position) until it stops. This prevents water from spraying out when you remove the old filter.

If you cannot find the valve behind the fridge, it may be under your sink or in a basement or crawl space where the water line originates. Check your fridge manual or Samsung's support site for your model if you are unsure. Do not skip this step — the pressure inside the line is enough to spray water across your kitchen floor.

Remove the old filter cartridge

For filters inside the fridge compartment: locate the filter cover (usually a white or stainless-steel panel in the upper right corner). Push the release button or twist the cover counterclockwise to open it. The cartridge itself either twists counterclockwise to release or slides straight out toward you, depending on your model. Have a towel ready — a small amount of water may drip when you pull it free.

For filters in the base grille: open the grille panel at the front bottom of the fridge. The filter cartridge sits horizontally inside. Locate the release button on the side or end of the cartridge and press it while sliding the filter straight out toward you. Again, have a towel underneath because water will drip.

Install the new filter cartridge

Before you insert the new filter, check that the rubber gasket (the seal ring) on the old cartridge did not stick to the housing. If it did, peel it out and discard it — the new cartridge comes with its own gasket. Wipe the inside of the filter housing with a clean cloth to remove any dust or debris.

Slide or twist the new cartridge into place, following the same motion the old one came out. For twist-in filters, turn clockwise until you feel resistance and hear a click — do not force it. For slide-in filters, push straight in until the cartridge seats fully and the release button clicks into place. Close the filter cover or grille panel.

Turn the water back on and flush the line

Turn the water shut-off valve counterclockwise (or flip the lever back to on). Wait 30 seconds for water pressure to build in the line. Then hold a cup under the water dispenser and run water for 30 seconds. This flushes air from the line and clears carbon dust from the new filter, which can make the water taste or smell off for the first few uses.

If water does not flow after 30 seconds, check that the shut-off valve is fully open and that the new cartridge is seated correctly. If water still does not flow, turn the valve off again, remove the cartridge, and confirm the gasket is in place and the housing is clear of debris.

When to replace your Samsung fridge filter

Samsung recommends replacing the filter every six months if you use the ice maker and water dispenser regularly. If you use them lightly (a few glasses of water per week), you can stretch it to 12 months. Some models have a filter indicator light on the control panel that turns red or blue when replacement is due — this is a rough guide, not a hard important date, because water hardness and sediment levels vary by location.

If your water tastes off, the ice maker produces cloudy ice, or the water pressure from the dispenser drops noticeably, the filter may be clogged before the recommended interval. Replace it early if any of these signs appear. Keeping a spare cartridge on hand means you can swap it out when ready instead of waiting for delivery.

Frequently Asked Questions

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

Yes, many third-party filters fit Samsung fridges and cost less than official Samsung cartridges. Check the model number on the package to confirm it matches your fridge model. Third-party filters perform the same basic filtration, though some users report different taste or longevity. If water quality or taste matters to you, buy one and test it before committing to that brand long-term.

What if water leaks from the filter housing after I install the new cartridge?

Turn off the water valve when ready. Remove the cartridge and check that the rubber gasket is seated properly in the groove — it should sit flat all the way around. Wipe the housing clean and reinstall the cartridge, pushing or twisting firmly until it clicks. If it still leaks, the gasket may be damaged; try a new cartridge. If a second cartridge leaks, the housing itself may be cracked and you should contact Samsung support.

Do I need to reset anything after I install a new filter?

Some Samsung models have a filter reset button on the control panel or inside the fridge. If your fridge has one, press it after installing the new cartridge to clear the indicator light. Not all models have this button — check your manual. If you do not reset it and the light stays on, it will not affect the filter's performance, only the reminder function.

How do I know if my fridge has the filter inside or in the base?

Open your fridge and look in the upper right corner for a small panel or cover. If you see one, your filter is inside. If not, crouch down and look at the front grille at the base of the fridge — you should see a horizontal cartridge or a panel that opens. Your model number on the fridge sticker will also tell you; search it on Samsung's website and the product page shows the filter location.
