Samsung DA29-00020B Replacement Filter (2026): Which One to Buy

Quick verdict

Best choice for most owners: a listed compatible. Waterdrop and ICEPURE both sell DA29-00020B replacements that hold NSF/ANSI 42 listings, at roughly a third of the genuine price per cartridge. Best choice if certification matters most: the genuine Samsung cartridge — it is the one listed in the NSF database under Samsung’s own name, with an exact-fit housing and lead-free construction noted in its listing. Either way, you are changing it twice a year, so the real decision is what a year costs: roughly $80–110 genuine versus $22–34 compatible, at the street prices we found in October 2026 (estimates).

First, confirm the DA29-00020B is your filter

Pull the old cartridge and read its label. The DA29-00020B is an internal filter that lives inside the fresh-food compartment, usually in the upper-right corner behind a small door or cap. If your Samsung’s filter sits on the back wall outside or in the bottom grille, you need a different part number entirely. Several numbers printed on Samsung cartridges are this same filter under different labels:

If your old cartridge carries the HAF-QIN code instead, it is the same filter family — our HAF-QIN replacement filter guide covers buying under that name. And if you want the full fit list and reset walkthrough for this cartridge, our DA29-00020B fit, reset and cost guide has it.

Your replacement options, compared

We researched and compared the options instead of guessing. Three tiers cover nearly everything sold for this part number:

The genuine cartridge’s listing covers chlorine reduction, taste and odor, and nominal particulate reduction (Class I) at a 300-gallon service cycle — a checkable listing, not a marketing bullet. Note what it does not cover: there is no certified lead-reduction claim on this filter, genuine or compatible. If lead is your concern, test first and look at filters with an NSF/ANSI 53 listing for lead.

How to spot a fake “genuine” filter

The DA29-00020B is one of the most counterfeited fridge filters sold online — fake “genuine” cartridges in copied Samsung packaging are a standing problem. Four checks catch most of them:

• Price. A “genuine Samsung” two-pack priced like a no-name multipack is not genuine. Real cartridges street at roughly $40–55 each.
• Print quality. Blurry label printing, misspelled words, or a label that peels or sits crooked are counterfeit tells. Genuine Samsung labels are crisp.
• The seller. Buy from Samsung, an appliance-parts retailer, or the brand’s own storefront — not a marketplace listing from a seller with no history.
• Weight and seal. A cartridge that feels noticeably light, rattles with loose media, or arrives unsealed is suspect. Send it back rather than installing it.

What the genuine premium actually buys

One reassurance whichever tier you pick: 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 damage caused by a badly made cartridge is still on you, which is one more reason to pick a listed brand over a no-name pack.

Fitting your replacement

The short version: open the filter door in the upper-right of the fresh-food compartment, pull or twist the old cartridge out, push the new one up until it clicks, then run 2–4 gallons through the dispenser to clear carbon fines and air. Reset the light by holding the Water Filter or Filter Reset button for about 3 seconds — on models without that button, hold Ice Type plus Child Lock together, and on Family Hub models use Fridge Manager. If the light stays on after a swap, our Samsung filter light reset guide walks through the stubborn cases. Most housings have an auto-shutoff valve, so you usually do not need to turn the water off — your manual has the final word for your model.

Conclusion

For a DA29-00020B replacement filter, the honest choice is between paperwork and price. The genuine Samsung cartridge (roughly $40–55) buys a checkable NSF/ANSI 42 listing and a guaranteed fit. A Waterdrop or ICEPURE compatible (roughly $11–17) keeps an NSF/ANSI 42 listing and cuts a year of filters to under $35. Both are rated 6 months or 300 gallons, both swap in under two minutes, and neither certifies lead reduction. Whichever you buy, buy it from a seller you can name — with this part number, the fakes are the real risk.
