Samsung DA29-00003G — which replacement filters fit, and which are actually certified

If your Samsung fridge cartridge is marked DA29-00003G (also sold by Samsung under the retail alias HAF-CU1/HAFCU1-XAA), here's the short version. The genuine Samsung element is NSF/ANSI 42 and 53 listed. A certified aftermarket option exists from Waterdrop as the EFF-6011S unit — but read the element carefully: the WD-DA29-00003G element is NSF 42 only; NSF 53 certification in that family attaches only to the WDS- and WDP-DA2900003G variants. "Fits" and "certified to reduce a contaminant" are not the same thing, and neither aftermarket part carries a manufacturer-verified OEM cross-reference.

Fitment table

Every row below comes verbatim from data-xref (site repo, commit c1ddb36) with certification detail from data-nsf, both checked 2026-08-15. The compatibility verdict is copied exactly as filed: claims-unverifiable — the NSF listing certifies each part, but states no OEM-to-aftermarket cross-reference, and no manufacturer-page confirmation exists today. That means these aftermarket parts are marketed as replacements; they are not verified-fitment claims on our side.

The one thing to keep straight: WD-DA29-00003G is not NSF 53 listed. NSF 53 certification within the Waterdrop EFF-6011S family attaches only to the WDS-/WDP- element variants, and their claim sets differ from each other (WDP adds Mercury). Don't pick the standard WD element expecting lead or other NSF 53 reductions.

What DA29-00003G is

Per Samsung's own Canada product page for HAFCU1/XAA (retrieved 2026-08-15), the alias maps directly: "DA29-00003G (replacing old model DA29-00003B and also compatible)", listed capacity 300 gal. Samsung's page for this retail model lists 91 compatible fridge models (RF263/265/266/267/268, RF28/29, RFG237–G299, RS21–RS28, RM257, and others). That list comes from the Canada-region page; Samsung's US product page is silent on the part-number mapping and publishes no model list, so the 91-model list rests on the Canada page only.

Certification detail per leg

Leg A — OEM (Samsung filing DA97-06317A, element DA29-00003G), listed under Microfilter Co., Ltd.:

• NSF/ANSI 42: Chlorine Reduction; Nominal Particulate Reduction, Class I; Taste and Odor Reduction. Cycle 300 gal, .4 gpm.
• NSF/ANSI 53: 2,4-D; Asbestos; Atrazine; Benzene; Carbofuran; Cyst; Lead; Lindane; Mercury; O-Dichlorobenzene; P-Dichlorobenzene; Turbidity; Monochlorobenzene; 1,2,4-Trichlorobenzene; Chlordane; Alachlor Reduction.
• Checked 2026-08-15 against NSF 42 and NSF 53, Samsung trade-name listings.

A second, distinct OEM filing exists (Samsung Electronics Co., Ltd., element list HAFIN2/EXP; DA29-00003G) with a different NSF 53 claim set (adds Chlorobenzene, Endrin, Ethylbenzene, Tetrachloroethylene, Toxaphene; lacks Monochlorobenzene, 1,2,4-Trichlorobenzene, Chlordane, Alachlor). It is listed separately in the base NSF table, not under the Samsung trade name. We attribute each claim to its own row and do not merge them. (This filing is not in the data-xref rows; listed here for completeness of the OEM record.)

Leg B — aftermarket (Waterdrop / Qingdao Ecopure, model EFF-6011S):

• Element WD-DA29-00003G: NSF 42 only — Chlorine; Taste and Odor Reduction (300 gal, .5 gpm). No NSF 53.
• Element WDS-DA2900003G: NSF 42 + NSF 53 (Cyst; Lead; Benzene; Carbofuran; Endrin).
• Element WDP-DA2900003G: NSF 42 + NSF 53 (the WDS list plus Mercury).
• Checked 2026-08-15 against NSF 42 and NSF 53, Waterdrop trade-name listings.

A final note on the aftermarket leg: as of 2026-08-15, waterdropfilter.com no longer lists any DA29-00003G product — the historical product URLs redirect and the store's full product sitemap has no entry. The NSF listing is still live, but the maker's own store no longer carries the part. A certification that later disappears is worth watching; we re-check on a schedule.

Chip / RFID / electronic filter lock

Samsung's product pages for this filter family describe no electronic filter lock — no chip or RFID requirement — so there is nothing in this platform that blocks a non-genuine cartridge from seating. What Samsung's page does mention is a physical "Authentication Tag" to verify the filter is genuine, and language that Samsung filters are "designed to work with Samsung refrigerators." The data-xref rows record chip_lock: false for both legs. Bottom line: no chip lock here, but the "designed to work" phrasing is a compatibility-adjacent claim, not a certification of contaminants.

Verify it yourself

The single ingredient that turns "a filter exists" into "a filter is certified" is the NSF listing, and it's public:

1. Open the NSF Drinking Water Treatment Units database.
2. Search the trade name (Samsung or Waterdrop) and the standard (042 or 053).
3. Confirm the element you're buying (DA29-00003G, WDS-, WDP-) appears in a listing dated when you read it — certification is element-specific, which is exactly where the WD-DA29-00003G trap hides.

We verify certification claims against public databases like this one; we don't lab-test. When a claim such as "compatible" isn't manufacturer-confirmed, we say so.

FAQ

Does the WD-DA29-00003G Waterdrop element remove lead? Not under NSF 53 — that element is listed under NSF/ANSI 42 for chlorine and taste & odor only. NSF 53 lead certification in this family sits with the WDS- and WDP- variants.

Is HAF-CU1 the same as DA29-00003G? Yes for fitment purposes — Samsung's Canada page states "DA29-00003G (replacing old model DA29-00003B and also compatible)" for HAFCU1/XAA. Note the US page doesn't publish that mapping.

Does my Samsung fridge have an RFID/chip filter lock? No chip or electronic lock is stated for this filter family. Samsung references a physical Authentication Tag for genuineness instead.

Is DA29-00003G the same as DA29-00003F? No. DA29-00003F is a different element (HAFIN1/EXP), listed at 500 gal and under NSF 42 — don't conflate the two.

A "compatible" filter is certified, right? Not automatically. The NSF database certifies the element's claims; compatibility between brands is a separate claim that, for these parts, is unverified as of 2026-08-15.

Method: all certification claims verified against the public NSF DWTU database on 2026-08-15; alias and fridge-model list from Samsung's Canada product page (2026-08-15). Compatibility verdicts are claims-unverifiable as filed in the site cross-reference data. We do not lab-test.
