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.
How to verify fit before buying Samsung RF28R6301SG Water Filter: HAF-QIN Replacement Guide
Treat compatibility as a model-number decision, not a shape-matching exercise. Start with the appliance or system model label, then confirm the exact cartridge or replacement code listed by the manufacturer. Similar-looking filters can use different tabs, seals, RFID features or bypass interfaces, so a cartridge that appears to fit can still leak, restrict flow or fail to lock correctly.
For aftermarket replacements, separate physical compatibility from filtration performance. A seller can correctly state that a cartridge fits a refrigerator while the contaminant-reduction scope differs from the original filter. If lead, cysts, PFAS or another health-related claim matters, verify the exact replacement model in the current certification or performance documentation rather than assuming an OEM-equivalent claim set.
Compare recurring cost, availability and replacement risk
Replacement products should be evaluated over several service cycles. Multiply the current cartridge price by the realistic replacement frequency, add shipping, and check whether the same model is consistently stocked. A low first-purchase price is less useful if the cartridge becomes difficult to source or if replacement intervals are short.
Watch for vague phrases such as “uses certified media” or “tested to a standard.” Finished-product certification is stronger evidence than a statement about one component. For marketplace listings, clear manufacturer identity, exact model numbers, return policies and traceable certification reduce the risk of counterfeit-style or poorly fitting replacements.
