DA29-00020B, HAF-CIN and HAF-CIN/EXP are the same Samsung filter. Read the number on your old filter, or look up your fridge model on Samsung's site. NSF lists Samsung's HAF-CIN (model DA97-08006A-1, model code DA29-00020B / HAF-CIN/EXP) for NSF/ANSI 42, 53 (lead, cysts and other chemicals) and 401, for 300 gallons.

- Waterspecialist WS627B: The best seller in this group on October 22, 2026. IAPMO lists Waterspecialist WS627B-A for lead, but the Amazon listing names WS627B, a different code. We could not confirm which one ships.
- GLACIER FRESH Z007: The Amazon listing says Z007 in its model field and GF-20B in its part field, two different codes. IAPMO R&T lists both under company Ningbo Pureza Technology: GF-20B for NSF/ANSI 42 only (W-10104), and Z007 for NSF/ANSI 42 and for lead, mercury and cysts (W-10104 and W-11601). We cannot tell which one you would get, so we do not show a buy button. Certificates current as of November 3, 2026.

Look at the model code, not the brand
The same factory often sells one copy in two versions that look alike. One is certified for taste and odor only. The other is also certified for lead. Only the model code tells them apart.
Water Specialist does the same: IAPMO lists the plain WS645A for taste and odor only, and WS645A-A and WS645A-U for lead. The code is in the Amazon listing's details (model or part number) and on the filter's label. Check it before you buy.
What the certifications mean
- NSF/ANSI 42: chlorine, taste and odor. It says nothing about lead or other health risks.
- NSF/ANSI 53: health. The listing names what was tested, such as lead, cysts or mercury. This is the one to look for.
- NSF/ANSI 401: small traces of some medicines and chemicals, such as ibuprofen and BPA.
- NSF P473: PFOA and PFOS, two PFAS "forever chemicals".

Questions people ask
Which Samsung refrigerator water filter do I need?
Pull out your old filter and read the number on its label. HAF-QIN and DA97-17376B are one filter. HAF-CIN and DA29-00020B are another. Samsung sells other filters too; this page covers these two. If you have no filter in hand, find your fridge model number on the sticker inside the fridge and look it up on Samsung's site.
Is HAF-QIN the same as DA97-17376B?
Yes. Samsung sells the same filter as HAF-QIN, HAF-QIN/EXP and DA97-17376B. NSF lists it under the system model DA97-08006C, rated for 316 gallons.
Are cheaper Samsung filter copies safe?
Some are certified to the same health standard as Samsung's filter and many are not. IAPMO R&T lists the Waterdrop WDS-F45 (HAF-QIN) and WDS-F27 (HAF-CIN) for lead and cysts under NSF/ANSI 53. The plain Waterdrop WD-F45, ICEPURE, RAMCO and Water Specialist WS645A are listed for taste and odor only.
Does the Samsung filter remove PFAS?
Not as far as the listings show. NSF lists Samsung's HAF-QIN and HAF-CIN for lead, cysts and traces of medicines, but not for PFOA or PFOS. The WaterSentinel WSS-4 (HAF-QIN) and WSS-2 (HAF-CIN) copies are: IAPMO R&T certificate W-11584 lists both for PFOA and PFOS.
How often should I change a Samsung fridge filter?
Samsung says every 6 months. The HAF-QIN is rated for 316 gallons and the HAF-CIN for 300 gallons. The certification only holds for those gallons.
