HAF-CIN and HAF-QIN are separate Samsung filter families. Preserve the exact SKU suffix when the manufacturer provides it.
Keep HAF-CIN and HAF-QIN separate
FitsMyModel does not normalize HAF-CIN and HAF-QIN into one generic Samsung filter. The exact refrigerator model and official filter terminology determine the result.
Do not drop “/EXP” automatically
Some official Samsung materials identify commercial SKUs such as HAF-CIN/EXP or HAF-QIN/EXP. When the source includes the suffix, the evidence record should preserve it.
Search by refrigerator model
Use the Samsung refrigerator filter guide and compare the exact source shown for your model. A filter family name by itself is not universal compatibility proof.
