Samsung Refrigerator Water Filter Replacement: DA29-00020B and DA29-00020A Guide for 2026
Samsung produces some of the most popular residential refrigerators in the US market, including the Bespoke line that lets homeowners customize panels and the standard French-door and side-by-side models that have been bestsellers for over a decade. If you own a Samsung refrigerator with a water dispenser, your replacement filter is almost certainly part of the DA29 series. Knowing which exact cartridge fits is the first step toward water quality that matches your refrigerator's design.
This guide covers the active Samsung refrigerator filter lineup, which models fit each cartridge, the difference between DA29-00020B and DA29-00020A, and how subscribe-and-save scheduling keeps Samsung owners ahead of the 6-month replacement cycle.
The Samsung Refrigerator Filter Lineup
Samsung uses the DA29 series for most of its residential refrigerators. The current production standard is the DA29-00020B, which replaced the older DA29-00020A. Both cartridges share the same housing geometry and are largely interchangeable, with the newer DA29-00020B offering improved filtration media.
| Cartridge | Common Use | Replaces |
|---|---|---|
| DA29-00020B | Current standard, most French-door and side-by-side | DA29-00020A |
| DA29-00020A (HAF-CIN) | Older standard, still in production | None |
| DA29-00003G (HAFIN1) | Older side-by-side models | Legacy models only |
| HAF-QIN (Bespoke) | Samsung Bespoke line | None |
| DA97-17376B | Older models with specific housing | Legacy only |
If your existing cartridge says "DA29-00020B," "DA29-00020A," "HAF-CIN," "HAF-QIN," or "HAFIN1" on the body, you have one of the matches in the table above.
DA29-00020B: The Current Samsung Standard
The DA29-00020B is the most commonly ordered Samsung refrigerator cartridge. It fits the majority of current-production Samsung French-door, four-door, and select side-by-side models.
Quick Specs
| Spec | Value |
|---|---|
| OEM part number | DA29-00020B |
| Replaces | DA29-00020A |
| Capacity | 300 gallons |
| Replacement interval | 6 months or 300 gallons |
| Connection | Twist-on quick-change |
| Certifications | NSF/ANSI 42 and 53 |
What the DA29-00020B Removes
- Chlorine taste and odor (NSF 42)
- Lead (NSF 53)
- Mercury (NSF 53)
- Cysts including Cryptosporidium and Giardia (NSF 53)
- Particulates Class I (NSF 42)
- VOCs (volatile organic compounds)
The DA29-00020B is NSF-certified to 42 and 53. It does not carry NSF 401 certification, which is the gap relative to LG LT1000P and Whirlpool EveryDrop cartridges. For most municipal water supplies the gap is minor. For households specifically focused on emerging contaminant reduction, the gap is worth understanding before choosing.
DA29-00020B Compatible Models
The DA29-00020B fits most current Samsung French-door and four-door refrigerators built from approximately 2014 forward. Common compatible model number prefixes:
- RF (French-door, four-door, and side-by-side)
- RH (side-by-side)
- RS (side-by-side)
- RFG (French-door with Family Hub)
- RSG (side-by-side with Twin Cooling)
Samsung publishes a compatibility list on its support site, indexed by refrigerator model number. If you cannot find a clear cartridge label in your existing filter, the refrigerator's model number sticker on the inside door is the fallback.
DA29-00020A and HAF-CIN: The Legacy Standard
The DA29-00020A, also marketed as HAF-CIN, was the Samsung standard before the DA29-00020B. Samsung continues to produce the DA29-00020A for the large installed base of older Samsung refrigerators, and the cartridge remains widely available.
Difference Between DA29-00020B and DA29-00020A
Both cartridges share the same housing geometry and the same NSF 42/53 certifications. The DA29-00020B uses improved filtration media that Samsung introduced in the 2018 production run. The cartridges are interchangeable in most Samsung refrigerators, with the DA29-00020B providing slightly improved contaminant reduction.
For Samsung refrigerators that originally shipped with the DA29-00020A, the DA29-00020B is a drop-in upgrade. For Samsung refrigerators that originally shipped with the DA29-00020B, ordering either cartridge is fine.
Samsung Bespoke (HAF-QIN)
Samsung's Bespoke line, introduced for the customizable-panel French-door refrigerators, uses a different cartridge format. The HAF-QIN is the cartridge for Bespoke refrigerators.
The HAF-QIN carries similar NSF 42/53 certifications and a 6-month replacement interval, but the cartridge connection is keyed differently from the standard DA29 series. Bespoke refrigerator owners should confirm the cartridge label before ordering. If your Samsung refrigerator was purchased as part of the Bespoke line and your cartridge says HAF-QIN, the standard DA29-00020B will not fit.
How to Replace a Samsung Refrigerator Filter
The replacement procedure is similar across DA29-00020B, DA29-00020A, and HAF-QIN. Total time is under two minutes plus a flush.
- Locate the cartridge. Samsung refrigerators position the filter in one of three places: inside the upper-right corner of the fresh food compartment, behind a bottom-grille panel at floor level, or inside the door near the dispenser on French-door models.
- Turn the existing cartridge counter-clockwise approximately a quarter turn. You will feel the cartridge release.
- Pull the cartridge straight out. A small amount of water will drip. Have a paper towel ready.
- Remove the new cartridge from packaging. Pull off the protective cap and avoid touching the O-ring with bare hands.
- Insert the new cartridge into the housing with the orientation matching the housing slot. Push gently and rotate clockwise a quarter turn until the cartridge locks.
- Reset the filter indicator by holding the "Filter Reset" or "Ice/Water" button on the control panel for 3 to 5 seconds. The procedure varies by Samsung model.
- Flush the new cartridge by dispensing approximately 2 gallons of water before drinking. The first cup or two may appear cloudy from carbon fines. The cloudiness clears within a minute.
When to Replace a Samsung Filter
Samsung specifies replacement every 6 months or 300 gallons of filtered water, whichever comes first. The 6-month calendar interval is the binding constraint for most households.
Signs the cartridge is past due:
- Filter indicator on the control panel
- Reduced flow from the water dispenser
- Returning chlorine taste in filtered water
- Slower ice production
- Cloudy water that does not clear within a minute
Subscribe and Save: Built for Samsung's 6-Month Cycle
The Samsung 6-month replacement cycle pairs well with subscription delivery. Every 6 months, a fresh cartridge arrives a few days before the install date with email reminders if you want them. Skip, pause, or cancel any shipment without penalty.
For multi-refrigerator households (Samsung primary kitchen unit plus a secondary refrigerator or wine cooler), coordinated subscription delivery ensures all cartridges replace on schedule.
Authentic vs Aftermarket Samsung Cartridges
The genuine Samsung DA29-00020B and DA29-00020A cartridges are manufactured to Samsung specifications with NSF 42/53 certifications. Aftermarket "Samsung-compatible" cartridges fit the same housings but vary in NSF certification and carbon density.
Things to verify on any aftermarket cartridge:
- NSF 42 and 53 certification printed on the packaging
- O-ring fit matches the original Samsung housing dimensions
- Carbon density matches the original specification
- Manufacturer reputation for consistent quality
The price difference between authentic Samsung and aftermarket is usually small enough that the OEM cartridge is the right choice. For Bespoke (HAF-QIN) cartridges specifically, OEM is strongly recommended because the cartridge connection is more sensitive to dimensional tolerances.

Frequently Asked Questions
What is the difference between DA29-00020B and DA29-00020A?
Both cartridges share the same housing and NSF 42/53 certifications. The DA29-00020B uses improved filtration media introduced in 2018. The DA29-00020B is a drop-in replacement for the DA29-00020A.
Is the HAF-CIN the same as the DA29-00020A?
Yes. HAF-CIN is Samsung's marketing name and DA29-00020A is the OEM part number for the same physical cartridge.
Does the DA29-00020B fit my Samsung Bespoke refrigerator?
No. Samsung Bespoke refrigerators use the HAF-QIN cartridge, which has a different connection geometry. Verify by checking the cartridge label on your existing filter.
Why does my Samsung refrigerator filter cost less than some other brand filters?
Samsung cartridges are NSF-certified to 42 and 53, which is the standard residential certification level. LG LT1000P, Whirlpool EveryDrop, and GE RPWFE/XWFE add NSF 401 certification, which tests for pharmaceutical and pesticide reduction. The price difference reflects the certification difference.
Can I subscribe to a multi-refrigerator household plan?
Yes. Subscriptions can be set up per refrigerator with coordinated delivery dates. Multi-cartridge subscriptions also stack the subscribe-and-save discount across all cartridges in the subscription.
Does the DA29-00020B remove fluoride?
No. The DA29-00020B removes lead, mercury, chlorine, cysts, and particulates. Fluoride removal requires a reverse osmosis system.
My Samsung filter indicator says replace but I just installed a new one. What is happening?
The indicator is calendar-based and needs to be reset after installation. Hold the "Filter Reset" or "Ice/Water" button on the control panel for 3 to 5 seconds.
