Quick take
The HAF-QIN family is the correct starting point. Confirm the exact regional suffix/model before checkout, then compare Samsung OEM with compatible DA97-17376B-family cartridges.
Model compatibility
Samsung documentation explicitly lists RF28R6301SG in the HAF-QIN compatible model set for the referenced market.
Regional suffixes matter
Samsung refrigerator model suffixes can vary by market, so use the full model code printed on the appliance when confirming a replacement.
OEM baseline
HAF-QIN publishes 300-gallon capacity and NSF 42/53 claims in Samsung documentation.
Aftermarket comparison
A compatible filter should clearly name HAF-QIN or DA97-17376B and document its own certification scope.
