A Samsung refrigerator can call for HAF-CIN, HAF-QIN or HAFCU1. Start with the code printed on the old filter, then confirm it against the refrigerator’s complete model and Samsung’s current support page.
Identify the cartridge before buying
Samsung’s U.S. support guide tells owners to check the existing filter’s model number. The filter location varies by refrigerator, so consult the exact model manual first. Keep the old cartridge until you have verified the replacement code.
When manufacturer pages appear to conflict
Some product listings use wildcard model patterns while another listing names a more complete model string. Our research records flag RS22HDHPNBC/AA and RF28HDEDPBC/AA for this reason. The fit check blocks automatic selection for those models. Compare the existing filter code and ask Samsung before ordering if the two sources disagree.
Installation and fit issues
Follow the current Samsung installation steps for your cartridge. Samsung also documents a lock-design change for HAFCU1 and troubleshooting for a filter that will not seat. Do not force a new cartridge into the housing or treat third-party fit wording as manufacturer approval.
