Samsung DA29-00020B / HAF-CIN Compatible Filters: What Fits and What's Certified

The quick answer

The Samsung DA29-00020B — sold at retail as HAF-CIN or HAF-CIN/EXP — is the replacement cartridge for a wide range of Samsung French-door refrigerators. The Samsung OEM cartridge is NSF 42 and NSF 53 certified, verified in the public NSF database on 2026-08-15. One aftermarket option, the Waterdrop WD-DA29-00020B (NSF-certified model EFF-6027S), carries its own independent NSF 42 and NSF 53 certifications. However, Waterdrop's claim that it fits the DA29-00020B slot is their manufacturer's statement — not a pairing the NSF database verifies.

Fitment table

What this filter is: untangling the names

If you have searched this part number, you have probably seen at least four different strings for the same cartridge slot. Here is what each label actually refers to, based only on the NSF listings and compatibility claim in our filed data:

DA29-00020B is the replacement element — the cartridge you pull out and discard. This is the identifier listed in NSF's "Replacement Element" column and the one printed on the filter itself.

DA97-08006A (and its extended variant DA97-08006A-E) is the NSF-listed assembly or product designation — the system under which Samsung's two certified manufacturers filed their NSF listings. These two filings reflect different component manufacturers: Altwell Tech Inc. filed DA97-08006A-E and Microfilter Co., Ltd. filed DA97-08006A; both list DA29-00020B as the replacement element.

HAF-CIN and HAF-CIN/EXP are retail SKU names on store shelves and in Samsung's consumer materials. The retail SKU HAF-CIN/EXP appears in the NSF certification database under Handok Clean Tech Co., Ltd. (assembly DA9708006A-H, element DA29-00020B). The Altwell, Microfilter, and Waterdrop filings this page covers use element DA29-00020B under assemblies DA97-08006A-E, DA97-08006A, and EFF-6027S respectively. They appear in Waterdrop's manufacturer compatibility claim, which lists "HAF-CIN, HAF-CIN-EXP, HAF-CIN EXP" among the replacement models its filter covers.

WD-DA29-00020B is Waterdrop's consumer-facing model name for their aftermarket replacement cartridge. The NSF-certified product within that model family is filed under the designation EFF-6027S by manufacturer Qingdao Ecopure Filter Co., Ltd.

Certification detail

The NSF database records two separate OEM Samsung filings and one aftermarket Waterdrop filing for this cartridge slot.

Samsung DA97-08006A-E (Altwell Tech Inc.) — NSF 42 + NSF 53

Verified at Std 042 and Std 053, checked 2026-08-15.

NSF 42 (aesthetic effects, 3 claims): Chlorine Reduction; Nominal Particulate Reduction, Class I; Taste and Odor Reduction.

NSF 53 (health effects, 18 claims): 2,4-D Reduction; Asbestos Reduction; Atrazine Reduction; Benzene Reduction; Carbofuran Reduction; Chlorobenzene Reduction; Cyst Reduction; Endrin Reduction; Ethylbenzene Reduction; Lead Reduction; Lindane Reduction; Mercury Reduction; O-Dichlorobenzene Reduction; P-Dichlorobenzene Reduction; Tetrachloroethylene Reduction; Toxaphene Reduction; Turbidity Reduction; 1,2,4-Trichlorobenzene Reduction.

Samsung DA97-08006A (Microfilter Co., Ltd.) — NSF 42 only

Verified at Std 042, checked 2026-08-15. This filing does not appear in the NSF 53 harvest; NSF 53 should not be assumed for this manufacturer's filing.

NSF 42 (3 claims): Chlorine Reduction; Nominal Particulate Reduction, Class III; Taste and Odor Reduction.

Waterdrop EFF-6027S (Qingdao Ecopure Filter Co., Ltd.) — NSF 42 + NSF 53

Verified at Std 042 and Std 053, checked 2026-08-15.

NSF 42 (2 claims): Chlorine Reduction; Taste and Odor Reduction.

NSF 53 (6 claims): Cyst Reduction; Lead Reduction; Benzene Reduction; Carbofuran Reduction; Endrin Reduction; Mercury Reduction.

Compatibility claims vs. certification: not the same thing

Both the Samsung OEM filter (Altwell filing) and the Waterdrop EFF-6027S hold NSF 42 and NSF 53 certifications. But "this filter is NSF-certified" and "this aftermarket filter is certified to fit my slot and reduce the same contaminants as the OEM" are different statements — only the first is verifiable in a public database.

The NSF database certifies the filter product, not that one manufacturer's cartridge is an equivalent replacement for another's. No OEM-to-aftermarket pairing appeared in our NSF DWTU check on 2026-08-15.

The claim that the Waterdrop WD-DA29-00020B fits the DA29-00020B / HAF-CIN slot is Waterdrop's own statement. Its product page states in the "Replacement Models" section: "DA29-00020B, DA29-00020A, HAF-CIN, HAF-CIN-EXP, HAF-CIN EXP..." and elsewhere: "The filter perfectly fits Samsung." (https://www.waterdropfilter.com/products/samsung-da29-00020b-refrigerator-water-filter-nsf-53-certified, accessed 2026-08-15.) That is a manufacturer claim. We cannot independently verify it through the NSF database, and we have not lab-tested physical fitment.

There is also a meaningful scope difference in the certified contaminant lists. The OEM Samsung cartridge (Altwell filing) holds NSF 53 certification across 18 contaminant reduction claims — including lead, asbestos, atrazine, mercury, and a broad set of organic compounds. The Waterdrop EFF-6027S holds NSF 53 certification for 6 contaminant reduction claims: cysts, lead, benzene, carbofuran, endrin, and mercury. Both filters are NSF 53 certified. "Fits" is not the same as "certified to reduce the same list." If the full 18-claim coverage matters to you, that distinction is worth weighing.

Verify it yourself

Every claim above is checkable directly in the NSF database:

1. Go to the NSF DWTU listings at https://info.nsf.org/Certified/DWTU/listings.asp. Choose a standard (42 or 53), enter the trade name (Samsung or Waterdrop), and run the search.
2. Find the Replacement Element column. The assembly designation (DA97-08006A-E) and the replacement cartridge (DA29-00020B) are listed separately.
3. Read the claim list in that row. An NSF 53 listing is only as broad as the contaminants named in that filing's claim list; checking the list tells you which contaminants are covered.

FAQ

What is the difference between HAF-CIN and HAF-CIN/EXP?

Both are retail naming variants for the same DA29-00020B replacement cartridge. Samsung has used both forms on packaging and in appliance manuals across model years. The retail name HAF-CIN/EXP does appear in the NSF database — under Handok Clean Tech assembly DA9708006A-H (element DA29-00020B). The filings this page covers (Altwell DA97-08006A-E, Microfilter DA97-08006A, Waterdrop EFF-6027S) use the element number without the retail suffix.

Is the Waterdrop WD-DA29-00020B actually NSF certified, or does it just "meet NSF standards"?

The Waterdrop EFF-6027S has a verified listing in the public NSF DWTU database under both Standard 42 and Standard 53 (NSF 042, NSF 053, checked 2026-08-15). This is a genuine third-party listing. The phrase "meets NSF standards" used by some sellers signals a self-assessment without an actual listing — a weaker claim. What NSF does not verify is the physical fit between the Waterdrop cartridge and your refrigerator's filter slot; that pairing claim comes from Waterdrop.

How often should I replace the DA29-00020B?

Both Samsung OEM filings and the Waterdrop EFF-6027S filing list a 300-gallon service cycle. Your refrigerator's filter indicator light should be your primary replacement prompt.

Does using an aftermarket filter damage the refrigerator?

Our filed data does not cover this question — it is outside the scope of a certification cross-reference page. Consult your refrigerator's owner's manual directly.

Will using an aftermarket filter void my Samsung warranty?

Also outside our filed data. Warranty terms are Samsung's to define, not a certification question we can answer.
