Filter	Certification verification
Frigidaire EPTWFU01 (OEM)	Not in our dataset

How to read this: a filter counts as certified only when its exact model number appears in the NSF, IAPMO R&T, or WQA public databases under a drinking-water filtration scope. Marketing phrases like “meets NSF standards” or “tested to NSF/ANSI 42” are not certifications — our verification study found that 56% of listings claiming certifications are not backed by the databases for the model sold.
