How to replace a Samsung refrigerator water filter (HAF-CIN, HAF-QIN, DA29 series)

Replacing a Samsung refrigerator water filter is a 3-minute job

Samsung designs their filters for quick, tool-free replacement. Whether you have a French-door, side-by-side, or bottom-freezer model, the process is straightforward. This guide covers the most common Samsung filters: DA29-00020B (HAF-CIN), HAF-QIN, and DA29-00003G.

Identify your Samsung filter first

• Samsung DA29-00020B (HAF-CIN) — 2012+ French-door and side-by-side models
• Samsung HAF-QIN — 2020+ models
• Samsung DA29-00003G — pre-2012 models

Replacing the DA29-00020B and HAF-QIN (twist-in interior filters)

1. Open the refrigerator and locate the filter compartment in the upper-right corner.
2. Press the filter release button (on models with a button) or turn the filter counterclockwise about a quarter turn.
3. Pull the filter straight out. A small amount of water dripping is normal.
4. Remove the cap from the new filter if present, and line up the arrow on the filter with the arrow on the housing.
5. Push in and turn clockwise until the filter locks in place.
6. Run 2–3 liters of water through the dispenser to flush the system before drinking.
7. Reset the filter indicator — typically by pressing and holding the “Ice/Water” button or a dedicated filter reset button for 3 seconds.

Replacing the DA29-00003G (older models)

1. Locate the filter — typically in the lower-left interior or bottom grille depending on your model.
2. Turn counterclockwise to unlock and remove.
3. Install the new filter by aligning and turning clockwise until snug.
4. Flush thoroughly — at least 2 liters — before using water for drinking or ice.

Common issues and fixes

• Filter leaks after installation: Remove and reinstall, making sure it’s fully seated and locked.
• Water dispenser is slow: Air bubble in the line — flush more water through the dispenser.
• Cloudy or grey water: Normal for the first few glasses after installing a new carbon filter. Flush until water runs clear.
• Filter light won’t reset: Hold the reset button for 5 full seconds. On some models, the fridge needs to be in cooling mode for the reset to work.

How often should you replace your Samsung water filter?

Samsung recommends every 6 months or every 300 gallons, whichever comes first. A household that uses the water dispenser daily will likely need replacement closer to every 4–5 months in practice.
