If the water from your Samsung refrigerator has started tasting flat, or the dispenser has slowed to a trickle, the Samsung DA29-00020B water filter is almost always the part you are looking for. It is the genuine Samsung refrigerator filter for a large slice of the French-door and side-by-side lineup, and it carries a second name that trips a lot of shoppers up: HAF-CIN. Same filter, two labels. This guide covers which refrigerators the DA29-00020B fits, how to tell it apart from the filters it gets confused with, and how to swap it in without a service call.

Water Filters FAST stocks the part new buyers struggle to find at a big-box store, ships weekday orders placed before 1pm CST the same day, and keeps a real support line open at 855-789-FAST when a model number does not line up cleanly.

What the DA29-00020B Filter Actually Is

The DA29-00020B is a sealed carbon-block cartridge that sits inside the fridge compartment, usually in the upper-right corner or along the back wall near the ceiling. Water passes through the carbon as it heads to the dispenser and the ice maker, and the carbon reduces the taste and odor of chlorine along with common sediment. It is a residential refrigerator filter, built for the water a household actually drinks and freezes, not a whole-house system.

Two part numbers point at the same cartridge. Samsung sells it as the DA29-00020B and also references the HAF-CIN code on packaging and inside owner manuals. If a manual lists HAF-CIN/EXP and the store shelf says DA29-00020B, that is the match, not a different part.

Most versions of this cartridge are certified to NSF/ANSI 42 for chlorine taste and odor reduction, which is the standard that backs up the better taste people notice after a fresh filter goes in. It is a water-quality and convenience upgrade for the kitchen, nothing more.

Which Samsung Refrigerators It Fits

The DA29-00020B covers a wide span of Samsung models built across the last decade, which is exactly why it shows up in so many kitchens. It fits a large share of French-door and side-by-side units, including many in the RF, RFG, RS, and RH series. Model numbers in those families commonly call for this exact cartridge.

The fastest way to be certain is the number printed on the filter you are pulling out, or the one listed in the manual. If the old cartridge reads DA29-00020B or HAF-CIN, the replacement is settled. If you no longer have the manual, the model number on the sticker inside the fridge (often on the left wall near the crisper drawers) lets the team match it for you.

Two near-misses cause most of the wrong orders. The DA29-00003G, an older round filter, belongs to a different generation of Samsung refrigerators and does not interchange with the 020B. The other is the DA29-00020A, the prior revision of this same cartridge; the B is the current version, so when a manual or old filter reads 020B, that is what to buy. The single most common slip is a worn label where the final letter has rubbed off, which is why reading the code in good light, before checkout, settles things in seconds. The support team at Water Filters FAST matches DA29-00020B fitment by model number every day, so a quick call clears up any unit that is hard to read.

OEM Versus Compatible: A Straight Answer

Shoppers usually land on one of two choices. The genuine Samsung DA29-00020B is the original equipment cartridge, made to the spec the refrigerator was designed around. Aftermarket DA29-00020B filters are also widely sold; the better ones fit the same housing and are tested to the same NSF/ANSI 42 chlorine taste-and-odor standard, often at a lower price per cartridge.

Both seat in the same slot and twist into the same lock. The practical trade is straightforward. The genuine Samsung filter is the safe default when a household wants the exact factory part with no guesswork. A quality aftermarket filter is a sensible pick for anyone replacing on a schedule who wants to spend less over a year of changes. The catalog at Water Filters FAST carries both, so the decision stays with the buyer rather than the shelf.

How to Replace the DA29-00020B, Step by Step

Most DA29-00020B cartridges are a quarter-turn design, so the swap takes a couple of minutes and no tools.

1. Find the filter. On French-door models it usually sits inside the fresh-food compartment, upper right, behind a small door or tucked at the top. Some side-by-side units place it lower along an inside wall.
2. Release the old cartridge. Rotate it about a quarter turn counterclockwise until it releases, then pull it straight out. A little water may drip, which is normal, so keep a towel handy.
3. Prep the new filter. Take the cap off the new DA29-00020B if one is fitted, line up the cartridge with the housing, push it in, and turn it a quarter turn clockwise until it stops. It should feel snug, not forced.
4. Flush the line. Run about two to four gallons through the dispenser to clear trapped air and loose carbon fines. The water may sputter or look cloudy at first; that clears quickly.
5. Reset the indicator. Hold the filter-reset or ice/water button for roughly three seconds until the status light changes. The exact button is in the owner manual, and resetting it restarts the change-reminder clock.

How Often to Change It

A common interval for the DA29-00020B is about every six months, or sooner if the water flow drops or the taste turns. Buying two cartridges at once keeps a spare on the shelf and skips the mid-year scramble, which is a frequent move for anyone who would rather not think about it again until the next change. Households on harder or heavily chlorinated water often land on the shorter end of that six-month window, so a spare earns its keep faster.

Frequently Asked Questions

Is the HAF-CIN the same as the DA29-00020B?

Yes. HAF-CIN is Samsung's internal code for the same cartridge sold as the DA29-00020B. A manual that lists HAF-CIN/EXP is pointing at this filter.

Will an aftermarket DA29-00020B work in my Samsung fridge?

A quality aftermarket DA29-00020B drops into the same housing and installs the same way, and the reputable ones carry NSF/ANSI 42 certification. Buyers who want the exact factory part can choose the genuine Samsung cartridge instead; both are stocked.

What is the difference between the DA29-00020A and DA29-00020B?

The B is the newer revision and the one nearly all recent Samsung refrigerators take. The A is the older version. If your manual or old filter reads 020B, order the 020B.

Do I need a plumber to replace it?

No. The DA29-00020B is a quarter-turn cartridge that swaps by hand in a few minutes, with no tools and no shutoff required.

How do I reset the filter light after changing it?

Hold the filter-reset or ice/water button for about three seconds until the indicator changes. The exact button varies by model and is listed in the owner manual.
