The most widely used Samsung refrigerator cartridge, fitted to RF22 through RF30 and most RS side-by-side models. Sold as HAF-CIN/EXP outside North America.
About this cartridge
DA29-00020B is a slim internal cartridge mounted on the upper left wall of the fresh food compartment. It is rated at 300 gallons or six months, and certified to NSF/ANSI 42 and 53 — lead and mercury reduction is claimed, pharmaceuticals are not.
The part-number sprawl is the main source of ordering mistakes. DA29-00020A is the earlier revision and works in the same housing; HAF-CIN and HAF-CIN/EXP are Samsung's own retail codes for the identical cartridge. Resellers also list 46-9101, WF294 and DA97-08006A, which are cross-references rather than Samsung numbers.
Samsung changed filter design in later models — DA97-17376B (HAF-QIN) is a different shape entirely and does not fit these housings.

Replacing it
- Turn the old cartridge a quarter turn counter-clockwise and pull it straight out. Keep a towel under it — a few ounces of water will come out.
- Remove the protective cap from the new cartridge and check that the O-rings are seated flat in their grooves.
- Push it in and turn clockwise until it stops. Run two to three gallons through the dispenser to flush carbon fines, then reset the indicator.
