Where the filter sits and what you need before you start

Samsung refrigerator filters are usually located inside the fridge itself, most often in the upper right corner behind the crisper drawers or in the back wall. Some models put the filter in the bottom grille at the front. Open your fridge and look for a cylindrical cartridge about the size of a soda can, or check your model number in the manual to confirm the exact location — the manual is often taped inside the fridge door or available free on Samsung's website by entering your model number.

Before you start, order a replacement filter that matches your exact model number. Samsung filters are model-specific; using the wrong one can damage the water system or produce poor-tasting water. You can find the correct filter number on the old cartridge itself, on a label inside the fridge, or in your manual. You do not need any tools — the filter twists or slides out by hand.

Key Takeaways

  • Samsung filters are located inside the fridge, most commonly in the upper right corner or bottom grille, and you can find the exact spot in your model's manual.
  • Order a replacement that matches your model number exactly; using the wrong filter can damage the water system.
  • The old filter twists counterclockwise or slides straight out — no tools needed — and the new one goes in the same way.
  • After installation, run water through the dispenser for 30 seconds to flush air from the line and remove any carbon dust.
  • Most Samsung filters need replacement every six months, though this depends on your water quality and how much water you use.

Removing the old filter

Locate the filter cartridge and look at how it sits in the housing. Most Samsung filters twist out: grip the cartridge firmly and turn it counterclockwise about a quarter turn until it stops, then pull it straight toward you. Some models have a filter that slides straight out without twisting — if turning does not work, try pulling gently in the direction the cartridge points.

When the filter comes free, water may drip from the opening or the cartridge itself. Have a small bowl or towel ready. Do not panic if a small amount of water spills; this is normal. Once the old filter is out, look inside the housing to make sure no rubber seal or O-ring came out with it — these should stay in place on the new filter.

Installing the new filter

Remove the new filter from its packaging and look at the rubber seal on one end. This seal should face into the housing. Align the filter with the opening and push it in straight, then twist it clockwise until you feel it catch and stop — usually a quarter turn. Do not force it; if it does not turn smoothly, remove it and check that the seal is seated correctly.

Some models have a reset button on the filter housing or on the fridge's control panel. If yours does, press it now to reset the filter life counter. This tells the fridge's system that a new filter is installed and resets the replacement reminder.

Flushing the system after installation

After the new filter is in place, run water through the dispenser for about 30 seconds before you drink any. This flushes air from the water line and removes loose carbon dust that can make the first water taste or look off-color. The water may look cloudy or taste slightly of carbon for the first few uses — this is normal and will clear.

If you have an ice maker, run a few cycles to clear the line there as well. Some people prefer to discard the first batch of ice cubes made after filter replacement, though this is not required.

When to replace the filter and what affects timing

Samsung recommends replacing the filter every six months for most households. However, the actual timing depends on how much water you use and your local water quality. If you have hard water or high sediment, you may need to replace it more often. If you live alone and use very little water, it may last longer than six months.

Your fridge will show a reminder when the filter life counter reaches zero, usually a light on the control panel or a message on the display. You can also check the filter manually — if the cartridge looks dark or discolored, it is time to replace it. Do not ignore the reminder; a clogged filter reduces water pressure and can affect ice maker performance.

Troubleshooting common problems

If water pressure from the dispenser drops after you install a new filter, the filter may not be seated correctly. Remove it and reinstall, making sure the rubber seal is fully inside the housing before you twist it in. If pressure is still low, run water for a full minute to ensure the line is fully flushed.

If water leaks from the filter housing after installation, the seal may not be seated properly or the cartridge may be slightly misaligned. Turn off the water supply to the fridge (usually a valve behind or under the unit), remove the filter, and check that the seal is clean and undamaged. Reinstall the filter, making sure it sits flush in the housing.

If the water tastes or smells bad even after flushing, the old filter may have been overdue for replacement. Run water for several more minutes; sometimes it takes longer to clear. If the problem continues, contact Samsung support with your model number — a faulty new filter is rare but possible.

Frequently Asked Questions

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

Third-party filters that fit Samsung models exist and are usually cheaper, but Samsung does not warrant them and they may not filter as effectively. If you choose to use one, make sure it is designed for your exact model number. Using a filter that does not fit properly can damage the water line or cause leaks.

What do I do with the old filter?

Most water filters can go in the trash, though some areas have recycling programs for them. Check your local waste guidelines. Do not pour the old filter down the drain or compost it.

Why is my water cloudy after I install a new filter?

Cloudiness after filter replacement is usually air bubbles in the line or loose carbon from the new filter. Run water for 30 to 60 seconds and the cloudiness should clear. If it persists after several minutes, the filter may not be seated correctly.

Do I have to reset the filter counter after installation?

If your model has a reset button, yes — pressing it tells the fridge that a new filter is installed and resets the replacement reminder. If you do not reset it, the reminder will continue to show even though the filter is new. Check your manual for the button location if you cannot find it on the control panel.

What happens if I do not replace the filter when the reminder shows?

A clogged filter reduces water pressure at the dispenser and can slow or stop ice production. The water may also taste or smell off. Continuing to use an overdue filter does not damage the fridge, but it defeats the purpose of having a filter. Replace it as soon as you can.
