DA29-00020B Replacement (2026): Fit, Reset & Cost
Guide
The red filter light on your Samsung fridge just came on, and now you are holding a part number — da29-00020b — with no idea which cartridge to buy, whether the cheap compatible ones are any good, or how to make that light go away. Genuine or third-party? How much does a year of filters actually cost?
Here is the short answer: the da29-00020b is Samsung’s slim internal filter, used in dozens of French-door and side-by-side models. The genuine cartridge is listed in the NSF database under NSF/ANSI 42 for chlorine, taste and odor, and particulate reduction, and it is rated at 6 months or 300 gallons. Swapping it takes under two minutes, the indicator resets with a short button hold, and a year of genuine cartridges runs roughly $80–110 versus under $30 for a decent compatible. This guide covers which fridges it fits, genuine vs compatible, the reset steps, and the real yearly math.

Which Samsung fridges use the da29-00020b
The da29-00020b is an internal filter: it lives inside the fresh-food compartment, usually in the upper-right corner behind a small door or cap marked LOCK, and it feeds both the water dispenser and the ice maker. If your Samsung fridge has an external filter on the back wall or the bottom grille instead, you need a different part number entirely.
Several part numbers are the same filter under different labels. Any of these on your old cartridge means the da29-00020b is the right replacement:
| Part number | What it is |
|---|---|
| DA29-00020B | Current Samsung part number |
| DA29-00020A | Previous revision of the same filter |
| DA29-00019A | Earlier revision, same housing |
| HAF-QIN / HAF-QIN/EXP | Samsung’s alternate model code for this filter |
| DA97-08006A | Samsung system code printed on genuine packaging |
| 46-9101 | Kenmore cross-reference number |
Popular Samsung fridge models that use it include the RF23J9011SR, RF260BEAESR, RF261BEAESR, RF263BEAESR, RF263TEAESG, RF28HDEDBSR, RF28HFEDBSR, RF323TEDBSR, RF4267HARS, RF4287HARS, and RH22H9010SR — plus dozens more across the RF, RS, RFG, and RH families. The fastest check is still the rating plate inside your fridge or the label on the old cartridge itself.

Genuine vs compatible da29-00020b filters
Third-party da29-00020b compatibles are everywhere, usually at a third of the genuine price. The housings match, the water flows, and most owners report no leaks. So what does the genuine cartridge actually buy you? We researched and compared instead of guessing: the answer is certification.
The genuine Samsung da29-00020b is currently listed in the NSF public database (info.nsf.org) under NSF/ANSI 42 for chlorine reduction, taste and odor reduction, and nominal particulate reduction (Class I), with a 300-gallon service cycle at 0.5 gpm and lead-free [Pb] construction. That is a checkable listing, not a marketing bullet. Some third-party brands (certain ICEPURE and Waterdrop listings, for example) also hold NSF/ANSI 42 listings — but most compatibles carry only the brand’s own claims, which is not the same thing.
Genuine Samsung — pros
- Database-verified certification — current NSF/ANSI 42 listing for chlorine, taste and odor, and particulates, checkable at info.nsf.org.
- Exact-fit housing — built to Samsung’s dimensions, so sealing and valve engagement are never a question.
- Lead-free [Pb] construction — per the NSF listing’s plumbing compliance note.
Genuine Samsung — cons
- 3–4x the price of compatibles — the certification and fit cost real money every six months.
- Counterfeits are common — “genuine” two-packs at suspiciously low prices are usually fakes; buy from reputable sellers.
- Narrower claim list than some rivals — NSF/ANSI 42 covers taste and particles, not the wider contaminant lists of higher-rated filters.
| Genuine Samsung | Third-party 3-pack (e.g. ICEPURE-style) | Third-party single (e.g. Mist-style) | |
|---|---|---|---|
| Price per filter | ~$40–55 | ~$11–14 | ~$14–17 |
| Rated life | 6 months / 300 gal | 6 months / 300 gal (claimed) | 6 months / 300 gal (claimed) |
| Certification | NSF/ANSI 42 — listed in NSF database | Varies: some NSF-listed, most brand-stated only | Usually brand-stated only |
| Fit | Exact | Matches dimensions | Matches dimensions |
| Best for | Certified filtration and exact fit | Budget rebuy with a listed brand | Trying one before committing |
One reassurance: using a compatible filter does not void your fridge warranty. Under the Magnuson-Moss Warranty Act, a manufacturer generally cannot void coverage just because you used a third-party part — though a leak caused by a badly made cartridge is still on you, which is another reason to pick a listed brand.
We ran the same genuine-vs-compatible comparison for Frigidaire’s filters in our WF3CB vs ULTRAWF comparison — the pattern is identical: the genuine cartridge buys you the checkable certification, the compatible buys you the savings.
How to replace it and reset the filter light
No tools needed, and it takes under two minutes:
- Find the housing. Open the fresh-food compartment and look in the upper-right corner for a small door or cap marked LOCK.
- Remove the old cartridge. On most models, press the release button and pull the cartridge straight down. On twist-lock models, rotate it a quarter-turn counterclockwise and pull it out.
- Insert the new cartridge. Unwrap it, push it up into the housing until it clicks. On twist models, insert and rotate a quarter-turn clockwise until it locks — a filter that is not fully seated is the number-one cause of slow flow after a swap.
- Flush the dispenser. Run 2–4 gallons through the water dispenser before drinking. The water may look grey or cloudy at first — that is carbon fines and trapped air from the new cartridge, and it clears as you flush.
- Reset the indicator light. The light does not reset itself, so do this every time:
- Most models: press and hold the Water Filter or Filter Reset touch button for about 3 seconds, until the light changes from red to blue/green or turns off.
- Side-by-side and French-door models without a dedicated button: press and hold Ice Type + Child Lock together for 3 seconds.
- Family Hub models: go to Apps > Fridge Manager > Fridge Settings > Water Filter and tap Reset.
- Water shutoff: on most models you do not need to shut off the water supply — the housing has an auto-shutoff valve. Your manual has the final word for your model.

Cost per year: genuine vs compatible
The filter is rated at 6 months or 300 gallons, so a normal household buys two cartridges a year. The yearly cost is just two times the per-cartridge price:
| Option | Price per cartridge | Cartridges per year | Estimated yearly cost |
|---|---|---|---|
| Genuine Samsung (single) | ~$40–55 | 2 | ~$80–110 |
| Genuine Samsung (2-pack) | ~$38–50 each | 2 | ~$75–100 |
| Third-party 3-pack | ~$11–14 | 2 | ~$22–28 |
| Third-party single | ~$14–17 | 2 | ~$28–34 |
The gap is real: genuine costs about 3–4 times the compatible per year — roughly $60–80 more annually — for the NSF-listed cartridge. A 3-pack of compatibles covers a full year with one cartridge to spare, which is why so many owners buy them in bulk.
For a second data point on fridge-filter math, Whirlpool’s EveryDrop EDR4RXD1 runs a similar yearly pattern — our EveryDrop EDR4RXD1 replacement guide breaks it down the same way.
Conclusion
The da29-00020b is one of the simplest filters to live with: it fits dozens of Samsung models, swaps in under two minutes, and the indicator light resets with a short button hold. Genuine cartridges run roughly $80–110 a year for the NSF-listed filter; a decent compatible cuts that under $30. Buy the genuine if you want the database-verified certification and exact fit, buy a listed compatible if you want the savings — and either way, change it on schedule, because a filter you leave in too long is just plumbing.

FAQs
How often should I replace the da29-00020b?
Every 6 months or 300 gallons, whichever comes first — that is the manufacturer’s rated life. Households with hard water or heavy sediment may need to swap sooner: slow dispenser flow or a taste change are the practical signals. The fridge’s indicator light is a timer, not a sensor, so treat it as a reminder rather than a measurement.
What does the da29-00020b replace?
The da29-00020b is the current part number for a filter family that also goes by DA29-00020A, DA29-00019A, HAF-QIN, HAF-QIN/EXP, DA97-08006A, and the Kenmore cross-reference 46-9101. If any of those numbers is printed on your old cartridge, the da29-00020b is the right replacement.
How do I reset the Samsung refrigerator filter light?
On most models, press and hold the Water Filter or Filter Reset touch button for about 3 seconds until the light changes from red to blue or green, or turns off. On side-by-side and French-door models without a dedicated button, hold Ice Type plus Child Lock together for 3 seconds. On Family Hub models, go to Apps, then Fridge Manager, then Fridge Settings, then Water Filter, and tap Reset. Button layouts vary, so check your manual for your exact model’s combination.
Are compatible da29-00020b filters as good as the genuine one?
For fit, usually yes — the housings match and most owners report no leaks. For certification, that is where they differ: the genuine cartridge holds a current NSF/ANSI 42 listing in the NSF database for chlorine, taste and odor, and particulate reduction, while most compatibles carry only the brand’s own claims. If you buy third-party, pick a brand that appears in the NSF database and be wary of “genuine” listings at impossibly low prices.
Does the da29-00020b remove lead?
Not as a certified claim. The genuine filter’s current NSF listing covers NSF/ANSI 42 only — chlorine reduction, taste and odor reduction, and nominal particulate reduction — with no certified lead-reduction claim. If lead is your concern, test your water first and look for a filter with an NSF/ANSI 53 listing for lead.
Do I need to shut off the water to change the da29-00020b?
Usually not. Most Samsung housings for this filter have an auto-shutoff valve that stops the water when the cartridge is removed. Your owner’s manual has the final word for your model, and it never hurts to know where your supply valve is before you start.
Why does my water look cloudy after installing a new filter?
Cloudy or grey-looking water right after a swap is normal — it is trapped air and loose carbon fines from the new cartridge. Run 2 to 4 gallons through the dispenser and it clears up. If the cloudiness persists after a full flush, remove and reseat the cartridge to make sure it is fully locked in.
