The Samsung DA97-17376B — sold as the HAF-QIN/EXP — is NSF 42 and 53 certified under three OEM manufacturer assemblies (NSF DWTU database, checked 2026-08-16). One aftermarket option, the Waterdrop EFF-6045S, is also NSF certified for this slot. The critical difference: the OEM NSF 53 listing covers 18 to 21 contaminants; Waterdrop's NSF 53 (WDS and WDP element variants only) covers three — Cyst, Lead, and Mercury. The base WD-DA97-17376B element carries no NSF 53 certification at all.

What is the difference between DA97-17376B, HAF-QIN/EXP, and the DA97-08006C assembly numbers?

Three kinds of identifiers describe this Samsung filter, and they are easy to mix up:

HAF-QIN vs HAF-CIN: These are different filters for different refrigerator slots. HAF-CIN (part number DA29-00020C) fits an older Samsung assembly slot. HAF-QIN/EXP (DA97-17376B) fits the newer integrated slot. Do not use them interchangeably.

Which Samsung OEM assemblies carry NSF 42+53 certification for the DA97-17376B?

Three manufacturers produce Samsung-branded assemblies that include DA97-17376B as a certified replacement element. All four assembly variants are NSF 42 certified; three carry NSF 53 as well.

Assembly Manufacturer NSF 42 NSF 53 NSF 53 claims Service cycle Flow rate Source (checked 2026-08-16)
DA97-08006C-A Altwell Tech Inc. ✅ ✅ 18 300 gal 0.4 gpm Std 042 · Std 053
DA97-08006C-H Handok Clean Tech Co., Ltd. ✅ ✅ 21 316 gal 0.4 gpm Std 042 · Std 053

DA97-08006C[Pb] Microfilter Co., Ltd. ✅ — — 316 gal 0.4 gpm Std 042

About the [Pb] suffix: The [Pb] designation is a material compliance notation — it indicates the assembly meets lead-free material requirements under NSF/ANSI 372 and applicable state laws (California, Vermont, Maryland, Louisiana) and the Safe Drinking Water Act. It is not a filtration claim. This assembly is NSF 42 certified only; it does not carry NSF 53 health-effects certification.

About the Microfilter dual-element listings: Both DA97-08006C[G] and DA97-08006C[Pb] are certified for two replacement elements: DA29-00020C (HAF-CIN slot) and DA97-17376B (HAF-QIN/EXP slot). Only the DA97-17376B element is in scope for this filter slot.

About HAF-QIN/EXP in the NSF database: The retail name HAF-QIN/EXP appears only in the Handok (DA97-08006C-H) listing as an alternate element designation. The Altwell and Microfilter listings do not name HAF-QIN/EXP; they list DA97-17376B only.

Is the Waterdrop EFF-6045S NSF certified for the DA97-17376B / HAF-QIN slot?

The Waterdrop EFF-6045S is the only NSF-certified aftermarket product found for this slot in the 2026-08-16 harvest. It has three element variants, and NSF coverage differs between them.

Element NSF 42 NSF 53 NSF 53 claims Service cycle Flow rate Source (checked 2026-08-16)
WD-DA97-17376B ✅ — 0 — NSF 42 only 316 gal 0.5 gpm Std 042
WDS-DA97-17376B ✅ ✅ 3 (Cyst, Lead, Mercury) 316 gal 0.5 gpm Std 042 · Std 053
WDP-DA97-17376B ✅ ✅ 3 (Cyst, Lead, Mercury) 316 gal 0.5 gpm Std 042 · Std 053

Which variant carries NSF 53? Only WDS-DA97-17376B and WDP-DA97-17376B. The base WD-DA97-17376B element is NSF 42 certified only — it carries no NSF 53 health-effects certification. If NSF 53 coverage matters to your purchasing decision, confirm before buying which element variant you will receive. The EFF-6045S model name covers all three variants in NSF's database, and packaging may not distinguish them clearly.

If you want NSF 42+53 coverage from this aftermarket option, look for the WDS or WDP element variants of the Waterdrop EFF-6045S (waterdropfilter.com, accessed 2026-08-16).

How does the OEM NSF 53 scope compare to the Waterdrop EFF-6045S for the DA97-17376B?

This is the most important comparison on this page. "NSF certified" is not the same as "certified to reduce the same list." Certified is certified — the scope varies significantly.

Filter NSF 42 NSF 53 NSF 53 claim count Notable NSF 53 contaminants
OEM Altwell (DA97-08006C-A) ✅ ✅ 18 Lead, Cyst, Mercury, Asbestos, Turbidity, Atrazine, Benzene, 2,4-D, Carbofuran, Chlorobenzene, and 8 more
OEM Handok (DA97-08006C-H) ✅ ✅ 21 All 18 above + Alachlor, Chlordane, Monochlorobenzene
OEM Microfilter (DA97-08006C[G]) ✅ ✅ 21 Same 21 as Handok
OEM Microfilter (DA97-08006C[Pb]) ✅ — — NSF 42 only
Waterdrop EFF-6045S (WD-DA97-17376B) ✅ — 0 NSF 42 only
Waterdrop EFF-6045S (WDS-DA97-17376B) ✅ ✅ 3 Cyst, Lead, Mercury
Waterdrop EFF-6045S (WDP-DA97-17376B) ✅ ✅ 3 Cyst, Lead, Mercury

Source: NSF DWTU database — Samsung brand, Std 053 · Waterdrop brand, Std 053, checked 2026-08-16.

The OEM NSF 53 scope covers pesticides (Atrazine, Lindane, Alachlor, Carbofuran, and others), industrial solvents and aromatic compounds (Benzene, Tetrachloroethylene, Ethylbenzene, and others), Asbestos, Turbidity, and heavy metals (Lead, Mercury). The Waterdrop WDS and WDP variants certify three of those: Cyst, Lead, and Mercury. Both certifications are genuine — but they are not equivalent in scope.

Waterdrop manufacturer compatibility claim

Waterdrop states this filter is compatible with the DA97-17376B / HAF-QIN/EXP slot (waterdropfilter.com, accessed 2026-08-16). We checked the NSF certifications against the public NSF DWTU database independently — we did not lab-test either filter. NSF certifies each product on its own merits; the database does not certify OEM-to-aftermarket pairings. The compatibility statement above is the manufacturer's own claim.

How often should you replace the Samsung DA97-17376B filter?

Filter Recommended interval NSF-tested capacity Flow rate
OEM Samsung (Altwell, DA97-08006C-A) 6 months 300 gal 0.4 gpm
OEM Samsung (Handok / Microfilter) 6 months 316 gal 0.4 gpm
Waterdrop EFF-6045S (all variants) 6 months 316 gal 0.5 gpm

Waterdrop’s manufacturer page recommends replacement every six months. For Samsung OEM assemblies, use up to 300 gallons or six months; NSF listings show 300–316 gallon service cycles. The gallon figures reflect the volume at which NSF certification conditions held during testing; NSF notes that capacity claims are not applicable for mechanical filtration.

Frequently asked questions

Is the Samsung DA97-17376B the same as HAF-QIN/EXP? Yes. DA97-17376B is the part number, and HAF-QIN/EXP is the retail name for the same replacement cartridge. In the public NSF database, both names appear together in the Handok Clean Tech listing for the DA97-08006C-H assembly. That listing treats HAF-QIN/EXP as an alternate element designation for DA97-17376B. The Altwell and Microfilter listings use DA97-17376B only. Samsung NSF database, checked 2026-08-16

What is the difference between HAF-QIN and HAF-CIN? They are different filters for different refrigerator slots. HAF-CIN is part number DA29-00020C; HAF-QIN/EXP identifies DA97-17376B. The Microfilter DA97-08006C[G] and DA97-08006C[Pb] assemblies list both elements, but this page covers only DA97-17376B. The newer integrated HAF-QIN/EXP slot is distinct from the older HAF-CIN slot, so do not substitute one for the other. Samsung NSF database, checked 2026-08-16

Does the Waterdrop EFF-6045S reduce lead? Only the WDS-DA97-17376B and WDP-DA97-17376B element variants carry NSF 53 certification for Lead Reduction. The base WD-DA97-17376B element is NSF 42 only and has no NSF 53 certification. The EFF-6045S name covers all three variants in the NSF database, so confirm the element variant before buying if lead reduction matters. Waterdrop NSF database, checked 2026-08-16

What does the [Pb] suffix mean on the Microfilter assembly? It is a material compliance notation: the assembly meets lead-free material requirements under NSF/ANSI 372 and applicable law. It is not a filtration performance claim. The DA97-08006C[Pb] assembly is NSF 42 certified only and does not carry NSF 53 health-effects certification. That suffix therefore does not mean the filter has certified lead reduction. Samsung NSF database, checked 2026-08-16

Which Samsung refrigerator models use the DA97-17376B / HAF-QIN filter? We cannot provide an authoritative Samsung model list from this research. The Samsung DA97-17376B product page and model finder were unavailable in the 2026-08-16 harvest. The Waterdrop page names RF28R7201SR and RF28R7351SG, but that is a competitor claim, not Samsung confirmation. Use Samsung model finder to check the part number before ordering. NSF certification verifies filter claims; it does not confirm refrigerator compatibility. Waterdrop page, accessed 2026-08-16

Is the Waterdrop WD-DA97-17376B adequate if I only care about taste and odor, not health-effects reduction? If your need is limited to chlorine, taste, and odor reduction, the base Waterdrop WD-DA97-17376B has NSF 42 certification for those claims. It has no NSF 53 certification, so it has no certified health-effects reduction claims, including lead. The WDS-DA97-17376B and WDP-DA97-17376B variants carry NSF 53 certification for Cyst, Lead, and Mercury. Confirm the element variant before buying: EFF-6045S covers all three variants, and packaging may not distinguish them clearly. Waterdrop NSF database, checked 2026-08-16 · NSF 53
