Samsung DA29-00003F (HAF-IN1): NSF 42 certified — not NSF 53

The Samsung DA29-00003F (HAF-IN1/EXP) is certified to NSF/ANSI Standard 42 — and that is where its certification stops. It is not certified to NSF 53. That means it carries no certification for lead reduction, cyst reduction, or volatile organic compound (VOC) removal. If you are buying an aftermarket replacement, the same ceiling applies: AQUA CREST AQF-00003F, Maxblue MB-00003F, and Waterdrop WD-00003F are all NSF 42 certified — and none holds NSF 53 certification either. All three are manufactured by Qingdao Ecopure Filter Co., Ltd. under the EFF-6011S element designation, verified in the public NSF Certified DWTU database (2026-08-16/17). This filter is a reasonable choice for improving chlorine taste and odor. For lead, cysts, or health-effects contaminants, it is not the right tool — and this page exists so you know that before you buy.

Does the Samsung DA29-00003F meet NSF 53 for lead reduction?

No. The DA29-00003F appears in the NSF Certified DWTU database under NSF/ANSI Standard 42 only. Its absence from the NSF 053 listing was confirmed directly against the public database (NSF Standard 053, Samsung, checked 2026-08-16 at info.nsf.org/Certified/DWTU/listings.asp?Standard=053&TradeName=Samsung).

Here is what the two standards cover, and why they are not interchangeable:

NSF 42 is a meaningful certification. It means the filter has been independently tested for chlorine taste and odor reduction and particulate performance. What it does not mean — and what only NSF 53 can mean — is lead or cyst reduction.

One mark to watch for on packaging: NSF/ANSI 372. That standard governs the lead content of the filter's own materials — a plumbing-materials rule — not whether the filter removes lead from your water. A 372 listing does not substitute for an NSF 53 Lead Reduction claim.

If lead is a concern in your household, the DA29-00003F and its aftermarket equivalents do not address it. Look for a filter with an explicit NSF 53 Lead Reduction certification.

Which aftermarket DA29-00003F filters are NSF certified?

Three aftermarket brands are NSF certified for this filter family — AQUA CREST AQF-00003F, Maxblue MB-00003F, and Waterdrop WD-00003F. All three are NSF/ANSI 42 certified. None is NSF 53 certified.

Certification Comparison Table

Sources (NSF DWTU public listings):

Two scope differences to read before you buy:

Particulate reduction. The OEM DA29-00003F carries Nominal Particulate Reduction, Class III as a certified NSF 42 claim. None of the three aftermarket EFF-6011S products holds that claim. This is a genuine performance gap, not a labeling difference. If particulate reduction matters to you, the OEM holds a certification scope the aftermarket alternatives do not.

Service cycle. The OEM DA29-00003F is rated at 500 gallons under its NSF 42 certification. All three aftermarket brands are rated at 300 gallons — a 40 percent shorter replacement interval. That is a material difference.

Same manufacturer, same element. All three aftermarket brands are manufactured by Qingdao Ecopure Filter Co., Ltd. and filed in the NSF database under the same aftermarket element designation, EFF-6011S. From a certified-element standpoint they are the same product under three different brand names, with the same certification scope and the same service cycle rating.

Physical fit. No manufacturer documentation confirms physical compatibility for any of the three aftermarket brands with a Samsung DA29-00003F slot. All three carry an unverified physical fit status in our cross-reference database. "Claims compatibility" from a third-party listing is not manufacturer-confirmed fit — factor that into your purchase decision.

How does the DA29-00003F differ from the DA29-00003G?

The DA29-00003F is the predecessor filter. Samsung's current equivalent is the DA29-00003G (HAFCU1/XAA). Samsung has discontinued the HAF-IN1 product listing.

If your refrigerator specifies the DA29-00003F, the DA29-00003G is Samsung's currently stocked OEM option. However, these are two distinct part numbers. Do not assume they are universally interchangeable — verify compatibility with your specific model in Samsung's current parts documentation before ordering the 00003G as a substitute for the 00003F. A refrigerator specified for the 00003F may accept the 00003G; it may not. The manufacturer's parts catalog, not aftermarket marketing copy, is the authoritative source for that determination.

Is the AQUA CREST AQF-00003F a certified replacement?

The AQUA CREST AQF-00003F is NSF/ANSI 42 certified via the EFF-6011S element listing (manufacturer: Qingdao Ecopure Filter Co., Ltd., checked 2026-08-17 at info.nsf.org/Certified/DWTU/listings.asp?Standard=042&TradeName=AQUA+CREST). It is not NSF 53 certified.

The same applies to Maxblue MB-00003F and Waterdrop WD-00003F: all three brands share the same certified element, the same manufacturer, and the same certification scope — NSF 42 only, service cycle 300 gallons, no Nominal Particulate Reduction Class III claim.

"Certified replacement" deserves careful reading. NSF certifies the filter element for specific performance claims under specific test conditions. NSF does not certify physical fit or confirm compatibility with a particular OEM housing. The physical compatibility of any of these aftermarket filters with a Samsung DA29-00003F slot is unverified by manufacturer documentation. The fit may be fine — we simply cannot confirm it from available sources, and no manufacturer page does either.

What refrigerators use the Samsung DA29-00003F filter?

This is a known data gap. Samsung's original HAF-IN1 model finder page is no longer live, and we do not currently hold a verified list of refrigerator model numbers compatible with the DA29-00003F in our cross-reference database. We will not list models without a sourced entry.

To identify whether your refrigerator uses this filter: check the label on the filter compartment door, or look up the part number in your owner's manual. Samsung's current parts catalog may also cross-reference it if your fridge model predates the transition to the DA29-00003G. If your fridge specifies DA29-00003F and OEM stock is unavailable, check whether Samsung's parts catalog lists the DA29-00003G as compatible with your specific model before substituting.

How do I verify the DA29-00003F certification myself?

The NSF Certified Drinking Water Treatment Units (DWTU) database is the authoritative public source. It is free to search and requires no login.

Confirm NSF 42 certification:
info.nsf.org/Certified/DWTU/listings.asp?Standard=042&TradeName=Samsung
Checked 2026-08-16. The DA97-06317A-B filing appears here.

Confirm the absence of NSF 53:
info.nsf.org/Certified/DWTU/listings.asp?Standard=053&TradeName=Samsung
Checked 2026-08-16. The DA29-00003F (DA97-06317A-B) does not appear in this listing. Note: Samsung does have other NSF 53-certified filters at this link (including the DA29-00003G) -- only the DA29-00003F is absent.

For aftermarket brands, search by trade name (AQUA CREST, Waterdrop) or by manufacturer (Qingdao Ecopure Filter Co., Ltd.) in the NSF DWTU search at info.nsf.org/Certified/DWTU/ under Standard 042 and Standard 053.

How did we verify these certifications?

Certification claims were checked against the public NSF Certified Drinking Water Treatment Units (DWTU) database. Samsung NSF 42 and NSF 53 listings checked 2026-08-16. Aftermarket brand listings (AQUA CREST, Maxblue, Waterdrop) checked 2026-08-17. We verify claims against public databases; we do not lab-test filters. Where a certification was absent, we state the absence rather than imply it. Physical fit compatibility was not independently confirmed for any aftermarket brand; the unverified status reflects the absence of manufacturer documentation, not a confirmed incompatibility. Certifications and product listings change — re-check the linked NSF records before you buy.
