To change a Samsung refrigerator water filter, first identify the exact cartridge your fridge uses, then follow the removal and installation directions for that cartridge. Filter type, location, turn direction, indicator reset, and flushing amount vary by model and region, so do not assume one filter or procedure fits every Samsung refrigerator.
Identify the correct replacement filter
Check the refrigerator’s model code on its label and the part number printed on the existing cartridge. Use Samsung’s filter guidance and compatibility finder and your refrigerator’s user manual to confirm the replacement before buying. Samsung’s North American guidance names HAF-CIN, HAF-QIN, and HAFCU1 for some models; those codes are examples, not universal fits. UK models may use other types, including external HAFEX/EXP and internal HAFIN cartridges, as shown in Samsung’s UK replacement instructions.
The cartridge may be inside the refrigerator, often near the upper-right interior or lower drawers. Some models instead use an externally mounted inline filter. If you cannot find the cartridge or its code, consult the manual for the model rather than guessing.
Prepare the fridge and remove the old cartridge
For an internal cartridge, shut off the refrigerator’s water supply and dispense water until the flow stops. This relieves pressure and can make a stuck filter easier to remove. Keep a towel nearby; a few drops may escape when the cartridge comes out.

HAF-CIN or HAF-QIN
- Open the filter compartment.
- Turn the old cartridge counterclockwise until it unlocks. Depending on the housing, the turn may be about 90 or 180 degrees.
- Pull the cartridge straight out.
HAFCU1
- Locate the internal filter; on models covered by Samsung’s North American instructions, it is usually near the upper-right area.
- Twist the old cartridge counterclockwise to unlock it, then pull it down from the housing.
Other cartridge types can have different locations or removal directions. Follow the manual if the cartridge does not match these descriptions; do not force it.
Install the new filter
Remove the protective cap from the replacement cartridge before inserting it. For HAF-CIN and HAF-QIN filters, push the cartridge into the housing and rotate it clockwise until it locks; align the lock symbol with the compartment’s indicator line. For HAFCU1, push the cartridge up into the housing, turn it clockwise until secure, and align its notch with the arrow on the housing. Check the markings on the filter and housing rather than relying only on how far the cartridge turns.

Samsung recommends genuine filters and warns that filters from other manufacturers may cause fit or housing problems. That warning is Samsung’s guidance; it does not establish that every non-Samsung filter is unsafe. Whatever replacement you choose, verify compatibility with the exact refrigerator model.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteRestore water, flush the system, and reset the reminder
- Turn the water supply back on and check around the filter for leaks.
- Dispense and discard water to flush the new cartridge. Samsung’s North American guidance calls for about seven minutes or 10–12 large glasses; its UK instructions specify 10 litres, or about six to seven minutes, for the procedure described there. Follow your model’s manual if it specifies a different amount.
- Reset the filter reminder using the control specified in the manual. Samsung says many US models reset by holding Alarm, Water Filter, or Ice/Water for three seconds, but the button and sequence vary by model.
Samsung bases the replacement reminder on a six-month interval and recommends changing the filter every six months. Treat that as Samsung’s general recommendation; your model’s manual gives the relevant instructions for its filter and controls.

If the filter will not come out or fit
The old filter is difficult to remove
Shut off the water and dispense until flow stops to relieve pressure before trying again. A small amount of water dripping during removal can be normal. Samsung UK also advises keeping the cartridge horizontal during removal for the models shown in its instructions to minimize leakage.
The new cartridge will not lock into place
Samsung US describes a possible housing-lock issue: the old filter may not have fully opened the housing. Its troubleshooting guidance is to temporarily reinstall the old cartridge, press it into the housing, and turn it farther left until it cannot turn any further. Remove it, then try installing the replacement. Do not force the new cartridge; if it still will not fit, contact Samsung support.

The indicator does not reset or water flow is poor
Check the model manual for the correct reset control and confirm that the cartridge is fully seated and locked. If flow remains poor after the required flush, or there is a leak, stop using the dispenser and consult the refrigerator manual or Samsung support for model-specific troubleshooting.
