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

Most Samsung refrigerators have the water filter in one of two places: inside the fridge compartment in the upper right corner, or underneath the fridge behind a kick plate at the bottom front. Open your fridge and look in the upper right—you'll see a cylindrical cartridge about the size of a soda can, often with a blue or white plastic housing. If it's not there, crouch down and remove the kick plate (usually held by two screws or clips) to find it mounted horizontally underneath.

The filter type depends on your model year and refrigerator style. Samsung uses three main cartridge types: DA29-00003G (the most common, fits most models from 2000 onward), DA29-00020B (found in some French-door models), and HAF-CIN (a newer cartridge in recent models). Your model number is printed on a sticker inside the fridge, usually on the side wall or back. You can also check the current filter itself—the part number is stamped on the cartridge.

Before you buy a replacement, confirm the exact cartridge your model needs. Visit Samsung's website, enter your model number in the parts finder, and look for "water filter" in the results. This takes two minutes and prevents buying the wrong size.

Key Takeaways

  • Samsung water filters are located either in the upper right corner of the fridge or underneath behind the kick plate, depending on your model.
  • The most common cartridge is the DA29-00003G, but you must confirm your exact model number before purchasing a replacement.
  • The entire filter change takes about five minutes and requires no tools other than your hands.
  • After installing the new filter, run water through the dispenser for 2 to 3 minutes to flush out carbon dust and air pockets.
  • Samsung recommends replacing the filter every six months, though the actual interval depends on your water quality and usage.

Removing the old filter step by step

If your filter is in the upper right corner of the fridge, locate the cartridge and look for a small button or release tab on the side or bottom of the housing. Press or twist this button counterclockwise—the cartridge will either pop out or twist free. Some models require you to push the button while pulling the cartridge straight down. If you're unsure which direction, check the label on the housing itself; Samsung prints an arrow showing the correct rotation.

If your filter is underneath the fridge, remove the kick plate by unscrewing the two screws at the bottom corners or unclipping the plastic tabs. The cartridge sits horizontally in a housing. Locate the release button on the end of the cartridge closest to you, press it, and slide the cartridge straight out toward you. You may need to angle it slightly as it comes free.

Once the old filter is out, water may drip from the housing or the cartridge itself. Place a small bowl or towel underneath to catch it. Do not panic if a small amount of water spills—this is normal. Wipe the inside of the housing with a clean, dry cloth to remove any debris or sediment before inserting the new filter.

Installing the new filter correctly

Before opening the new cartridge, check that the rubber seals on both ends are intact and not cracked. If they are damaged, the filter will leak. Remove the plastic cap from the inlet end of the new cartridge (the end that faces the water line inside the fridge). Do not remove the cap from the outlet end—that stays on.

For filters that go in the upper right corner, align the cartridge with the housing opening and push it straight in until you hear a click or feel resistance. Then twist it clockwise until it stops—do not force it. The housing will feel snug when the filter is seated correctly. For filters underneath the fridge, slide the new cartridge straight into the housing until the release button clicks into place.

If the cartridge does not slide in smoothly, stop and check the alignment. Forcing a misaligned filter can crack the seal and cause leaks. The cartridge should glide in with gentle, steady pressure. Once it is fully seated, the housing should feel solid with no gaps.

Flushing the new filter before using it

After the new filter is installed, run water through the dispenser for 2 to 3 minutes without stopping. The water may look cloudy, gray, or black at first—this is carbon dust from the new filter and is harmless. Keep the water running until it runs clear. This step is important because it removes air pockets from the filter and prevents sediment from reaching your glass.

If you have an ice maker, run the dispenser for another minute after the water clears, then make a batch of ice and discard it. This ensures the ice maker lines are also flushed. Do not drink the water or use it for cooking until you have completed this flushing step.

What to do if water leaks after you install the filter

A small drip from the housing during installation is normal, but steady leaking after the filter is seated means the seal is not tight. First, check that the cartridge is fully inserted and twisted all the way clockwise (for top filters) or fully clicked in (for bottom filters). Sometimes a half-turn more will seal the leak.

If tightening does not stop the leak, remove the filter and inspect the rubber seals on both ends. If either seal is cracked, torn, or missing, the cartridge is defective and must be replaced. If the seals look intact, wipe the inside of the housing with a dry cloth and reinstall the filter, making sure it is aligned straight before pushing it in.

If leaking continues after reinstalling, the housing itself may be cracked or the water line connection may be loose. Check the water line connection at the back of the fridge—it should be hand-tight but not over-tightened. If the connection is loose, tighten it a quarter turn. If the housing is cracked, you will need to call a Samsung service technician to replace it.

How often to replace your Samsung water filter

Samsung recommends replacing the filter every six months. However, the actual interval depends on your water quality and how much water you dispense. If you have hard water or high sediment in your tap water, the filter will clog faster and may need replacement every three to four months. If you rarely use the dispenser, it may last longer than six months.

Most Samsung filters have a reset button on the housing that you can press to start a six-month countdown timer. After six months, a light on the fridge display will alert you that the filter needs replacement. This is a reminder, not a hard important date—the filter will continue to work, but its effectiveness decreases over time. If you notice the water pressure from the dispenser dropping or the water tasting different, replace the filter even if the timer has not reached six months.

Keep a replacement cartridge on hand so you are not caught without one. Buying filters in bulk from Samsung or a third-party supplier often costs less per filter than buying them one at a time.

Frequently Asked Questions

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

Yes. Third-party filters that match your cartridge type (DA29-00003G, DA29-00020B, or HAF-CIN) will fit and work in your refrigerator. Many are cheaper than Samsung brand filters. Check the product listing to confirm it is compatible with your exact model before ordering. The installation process is identical.

What if I lose the plastic cap that comes on the new filter?

The cap protects the inlet during shipping and storage. If you lose it before installation, you can still install the filter—just be careful not to touch the inlet opening with your fingers. If you have already installed the filter without the cap, it will not cause a problem. The cap is only needed during storage and transport.

Why is my water pressure low after changing the filter?

Air pockets trapped in the new filter reduce water pressure until they are flushed out. Run water through the dispenser for 2 to 3 minutes continuously. If pressure remains low after flushing, the filter cartridge may be installed backward or not fully seated. Remove it, check the alignment, and reinstall. If pressure is still low, the old filter may have been very clogged and the new one is working correctly—pressure should return to normal within a few days as the filter settles.

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

No. The refrigerator's water line has a shutoff valve built into the filter housing. When you remove the cartridge, this valve closes automatically and stops the water flow. You do not need to access the main water shutoff under your sink.

How do I know if my filter is clogged?

A clogged filter shows two signs: water pressure from the dispenser drops noticeably, or the water tastes or smells different than usual. If either happens before six months, replace the filter. You cannot clean or unclog a Samsung cartridge—they are designed to be replaced, not serviced.
