Use Frigidaire FPPWFU01 / PurePour PWF-1 or a compatible cartridge explicitly listed for that part number and refrigerator model.
Correct filter mapping
Frigidaire’s owner-support page for GRFS2853AF lists FPPWFU01 PurePour PWF-1 as the replacement water and ice filter.
OEM vs compatible
OEM FPPWFU01 is the simplest fit. Compatible cartridges can be cheaper if they clearly document PWF-1 compatibility and their certification.
Recurring cost
Frigidaire recommends periodic replacement, making this a recurring purchase rather than a one-time accessory.
Where to compare
Replacement-filter specialists can provide multiple compatible price points for PWF-1 owners.
How to verify fit before buying Frigidaire GRFS2853AF Water Filter: FPPWFU01 / PurePour PWF-1
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.
