Samsung DA29-00020B (HAF-CIN/EXP) water filter: fits, certification, reset

The short answer

• DA29-00020B is the replacement cartridge code for Samsung's HAF-CIN/EXP filter, used in system DA97-08006A-B ^[S3].
• Samsung rates it for 300 gallons ^[S1] and says to replace it every six months ^[S2].
• Samsung makes three filter types (HAF-CIN, HAF-QIN and HAFCU1), and they are not interchangeable. The quickest way to know which one you need is to read the model number on the filter that's already in your fridge ^[S2].

Fridge models Samsung lists for HAF-CIN

These are copied exactly as printed in the "Fits Models" field of Samsung's US product page ^[S1]. The ** stands for the end of the model number (color/finish code), which varies.

Samsung's page repeats some entries, which we list once. A few entries look like typos: for example "RF22ONCTA" may be meant as "RF220NCTA", with the letter O standing in for a zero. We've kept Samsung's exact text rather than guess. Unverified If your model is close to one of these but doesn't match exactly, don't assume it fits. Check the filter in your fridge or contact Samsung.

Certification: what NSF's listing shows

Samsung's support page says its water filters "meet NSF/ANSI standards 42, 53, and 401" ^[S2]. Its UK spec sheet lists NSF 42 (chlorine taste and odor) and NSF 53 (cysts, turbidity, lead, asbestos, benzene, carbofuran, p-dichlorobenzene and mercury) ^[S3].

We checked NSF's public listing. Searching the trade name DA29-00020B on October 21, 2026 returned Samsung Electronics Co., Ltd. listing "HAF-CIN/EXP DA29-00020B" as an integrated refrigerator filter under NSF/ANSI 42, 53 and 401 ^[S4]. Open the live NSF record to see the full list of claims.

The same search also returns listings from other manufacturers, including aftermarket filters, and their claims vary ^[S4]. Before you buy a cheaper "DA29-00020B compatible" filter, search NSF for that exact model number. Don't rely on the Samsung part number printed on its box.

How to replace it (Samsung's steps)

For HAF-CIN and HAF-QIN filters ^[S2]:

1. Turn off the water supply.
2. Open the filter cover and rotate the old filter counterclockwise to unlock and remove it.
3. Remove the protective cap from the new filter, insert it, and turn clockwise until it locks. Line up the lock symbol with the indicator line.

Samsung's UK spec describes the installation as "90° Rotate and Lock" ^[S3]. Afterwards, Samsung says to dispense several gallons of water to clear out air and impurities, then reset the indicator ^[S2].

How to reset the filter light

Samsung says the light runs on a six-month timer and should be reset each time you install a new filter. The steps depend on the model ^[S2]:

• Standard models: press and hold Filter Reset for three seconds.
• Family Hub: Apps → Fridge Manager → Fridge Settings → Water Filter → Reset.
• Models with arrow buttons: go to More Options → Filter Reset.
• RF4289 and RSG309: Settings → Water Filter, then hold Reset until the status changes.

Samsung's position on third-party filters

Samsung's support page tells owners to "Avoid third-party water filters as they may cause leaks and potentially damage your refrigerator" ^[S2]. Take that into account, along with your warranty terms, if you're weighing a cheaper filter.
