What Filter Does My Samsung Fridge Use?

[Published: July 11, 2026 | Last updated: July 11, 2026]

TL;DR

The fastest way to answer what water filter does my Samsung fridge use is to read the model number inside the fridge, then match that number to Samsung’s approved parts list.
Samsung refrigerator filters often use codes such as HAF-CIN/EXP, HAF-QIN/EXP, DA29-00020B, and DA97-17376B, but the right code depends on the exact fridge model.
A filter can look correct and still fail if the connector style, size, or regional suffix is wrong.
After installation, flush the new filter with several gallons of water, or follow the manual’s flush steps, so carbon dust and trapped air do not affect taste or flow.
The safest purchase path is Samsung’s parts lookup or the owner’s manual first, then the exact part number on the box before you open it.

What Water Filter Does My Samsung Fridge Use? Start With the Model Number

What water filter does my Samsung fridge use depends on the exact refrigerator model, not just the brand name. Samsung uses several filter formats, and the model number is the only reliable starting point for choosing the right replacement.

Samsung places the model number on a rating label or serial tag, often on the upper-left inside wall, the door frame, or behind a crisper drawer. That model number links the refrigerator to the correct filter family and part code.

Where to find the model number

The model number comes first because Samsung maps the refrigerator to the correct replacement parts through that code. Once you have it, you can search Samsung support, the owner’s manual, or a parts seller’s compatibility tool.

Use these common locations:

Inside the fridge compartment on a side wall.
On the ceiling or upper frame near the door hinge.
Behind a produce drawer or on the drawer frame.
On the original receipt, manual, or product registration page.

If the label is hard to read, take a photo and zoom in. The model number often looks like RF28T5001SR or RF23M8070SG, and that exact string matters more than the series name or finish color.

Why the model number matters more than the fridge appearance

Two Samsung fridges can look nearly identical and still use different filters. Door style, water line setup, and production year can all change the part number. A seller may list a broad compatibility range, but the model number is the safest way to avoid a bad match.

Match the Correct Filter Code

The correct filter code is the part number Samsung assigns to your fridge’s water filter. Once you have the model number, compare it with Samsung’s parts database or the filter chart in the owner’s manual to find the approved code.

Samsung refrigerator filters often appear under codes such as HAF-CIN/EXP, HAF-QIN/EXP, DA29-00020B, and DA97-17376B. These are common codes, not universal ones, so you still need to verify the exact match for your model.

How to read the filter code

The filter code is the actual part number, and the packaging should show it clearly on the front or side panel. Some replacement sellers also print the compatible Samsung model numbers on the box.

Check for three things:

The part number matches the one listed for your fridge model.
The connector style matches the filter housing inside the refrigerator.
The filter is sold for your region, since some Samsung parts use regional suffixes like /EXP.

If the code on the box differs from the code in your manual, treat that as a warning sign. A close-looking substitute can still fail to lock in or may not seal correctly.

Common Samsung filter codes and what they mean

Here is a simple reference for common Samsung filter codes. This list helps with recognition, but it does not replace model-based matching.

Filter code	Common use	Notes
HAF-CIN/EXP	Many Samsung side-by-side and French door models	Verify by model number before buying.
HAF-QIN/EXP	Many newer Samsung French door models	Often sold with twist-in style connectors.
DA29-00020B	Older and some current Samsung models	Check the regional suffix and fit.
DA97-17376B	Some newer Samsung refrigerators	Always confirm the exact model compatibility.

Samsung’s own parts lookup and owner manuals are the best references for code matching. Retail listings can help, but they should come after the manufacturer match.

Check Fit and Packaging Carefully

Fit and packaging are your last defense before installation. A filter can have the right code printed on the box and still be wrong if the seal is damaged, the connector differs, or the package has been opened and repacked.

Check the box before you open it. The label should show the part number, compatibility list, and any regional suffix. Look for a sealed package, an undamaged carton, and a clean filter body with no cracks, dents, or loose plastic.

What to inspect before opening the box

The box should tell you whether the filter is meant for your exact refrigerator family. If the seller includes a compatibility chart, compare your model number line by line instead of relying on a photo or a general “fits Samsung” claim.

Inspect these details:

The part number on the box matches your required filter code.
The connector shape matches the old filter and housing.
The packaging seal is intact and not resealed with tape.
The expiration or production date, if printed, is current enough for normal storage.

If the filter looks used, scratched, or rewrapped, return it. Water filters contain carbon and internal seals, so packaging damage can affect performance or hygiene.

Why fit matters even when the code looks right

Samsung uses twist-in, push-fit, and internal cartridge formats across different models. Think of the code as the street address and the connector as the front door key. If either one is wrong, the filter may not lock in or may leak.

Some aftermarket filters advertise broad compatibility, but broad compatibility is a claim, not proof. When in doubt, use Samsung-branded parts or a replacement maker that lists your exact model number, not only the fridge series.

Replace and Flush After Installation

Replacement and flushing complete the job. After you install the new filter, run water through it so trapped air and loose carbon particles clear out before drinking or using the ice maker.

Start by shutting off the water supply only if your manual asks for it. Many Samsung filters twist out and twist in without tools. Install the new filter firmly until it clicks or locks, then reset the filter indicator light if your model has one.

How to replace the filter

The exact replacement steps vary by model, but the process is usually simple. Remove the old filter, align the new one with the slot or twist connector, and rotate or push it until it seats fully.

Follow this sequence:

Open the filter housing or access panel.
Remove the old filter by twisting or pulling it out, depending on the design.
Insert the new filter in the correct orientation.
Lock it into place until it stops moving.
Check for leaks at the connector.

If the filter does not slide or twist smoothly, stop and recheck the model and code. Forcing it can damage the housing.

Why flushing is necessary

Flushing clears loose carbon fines and air pockets from the new filter. Those particles can make the first water cloudy or give it an odd taste. Samsung manuals commonly instruct users to flush the filter and discard the first several gallons, though the exact amount varies by model and filter type.

Follow your manual if it gives a specific flush amount. If it does not, run water until the flow is steady and the taste is normal. Then make a few ice batches and discard the first batch if the manual recommends that step.

Common Mistakes to Avoid When Choosing a Samsung Fridge Filter

The most common mistakes are guessing the part number, buying by fridge color or size, and ignoring the package details. Each one can lead to a filter that leaks, does not fit, or performs poorly.

Buying by refrigerator appearance

A French door Samsung fridge and another French door Samsung fridge can use different filters. Appearance is not a reliable selector because Samsung changes parts by model family and production run.

Use the model number instead. It gives you the exact part match and cuts down on returns.

Trusting a seller’s generic compatibility claim

A listing that says “fits most Samsung fridges” is too vague. It may include some models and exclude yours, especially if the seller mixes regional part codes.

Check the compatibility table on the listing, then compare it with Samsung’s documentation. If the seller does not list your exact model number, move on.

Skipping the flush step

Skipping the flush step leaves carbon dust, air, and stale water in the new filter. That can cause cloudy water, odd taste, or sputtering from the dispenser.

Flush the filter right after installation, and do not use the first water output for drinking unless your manual says it is ready.

Frequently Asked Questions About Samsung Fridge Water Filters

How do I know what water filter my Samsung fridge uses?

Read the model number inside the refrigerator, then match it to Samsung’s parts list or manual. That is the most reliable way to answer what water filter does my Samsung fridge use without guessing.

Can I use an aftermarket filter in my Samsung fridge?

Yes, if the aftermarket filter lists your exact model number and uses the correct connector and regional code. Samsung-branded filters are usually the simplest choice, but a well-made third-party filter can work if it matches precisely.

Where is the Samsung fridge model number located?

It is usually on a label inside the fridge, often on the left wall, upper frame, or behind a drawer. If you cannot find it there, check the original manual or product registration record.

Do Samsung water filters need to be flushed?

Yes, they usually do. Flushing removes loose carbon particles and trapped air, and Samsung manuals commonly require several gallons or a few minutes of flow before normal use.

What happens if I install the wrong Samsung filter?

The filter may not lock in, may leak, or may reduce water flow. In some cases, the dispenser will not work at all, so it is better to verify the part code before installation.

How often should I replace a Samsung fridge filter?

Most Samsung refrigerator filters are replaced about every six months, but usage and water quality can change that timing. If water flow drops or taste changes sooner, replace it earlier and follow the fridge display or manual guidance.

Do all Samsung fridges use the same filter?

No. Samsung uses several filter families across different models and years. The model number is the only dependable way to choose the right replacement.
