The water filter part number for the Samsung refrigerator model RF28HMEDBSR is typically HAF-CIN (or sometimes listed as HAF-CIN/EXP). This filter also replaces the older part number DA29-00020B.
Where to find it in the fridge: In this model, the water filter is usually inside the refrigerator compartment, between the two crisper drawers. You typically access it by twisting and pulling it down or out.
Recommendation:
You can double-check the part number on your current filter (if possible) or consult your refrigerator’s manual before purchasing a replacement to ensure compatibility. You can buy genuine Samsung or compatible third-party filters, but HAF-CIN (or DA29-00020B) is the specification you need to look for.
