Samsung uses three separate filter families in the published records. HAF-QIN aliases such as HAF-QIN/EXP and DA97-17376B do not turn HAF-CIN or HAFCU1 into substitutes.
Published model records
Choose the exact refrigerator model.
Each route keeps the documented device model, filter reference, region and manufacturer sources together. A source review records a documentary check against manufacturer materials; it does not mean the filter was physically fitted or tested.

QIN, CIN and CU1 select different families
The three published model answers keep HAF-QIN, HAF-CIN and HAFCU1 separate. Match the complete reference before comparing pack size.
A listed cartridge family does not establish fit for an unlisted appliance. Amazon products and reference searches, manufacturer pages and retailer pages are labelled separately. Amazon links are paid links.
