WFCB filter: genuine vs replacement

Last checked October 28, 2026

Check before you buy

We found no certification listing for the genuine Frigidaire PureSource WFCB itself in NSF, IAPMO R&T or WQA, as of our last check.

We found 10 replacement models listed by number: 2 cover NSF/ANSI 42, 53 and 401, and 4 are listed to NSF/ANSI 42 only, which covers taste and chlorine, not lead.

Verdict: check before you buy. The most complete listings we found belong to replacements such as EFF-WFCBA and Water Specialist WSWFCB-U; the genuine filter's own certification could not be confirmed in a public listing.

Genuine Frigidaire WFCB

No listing found for the genuine filter in the databases we searched: IAPMO, NSF, WQA. That does not prove it is uncertified; it means we could not confirm it in a public listing.

No certificate we found names WFCB itself. Frigidaire's data sheet points to IAPMO R&T listings for its WFCB-P200 and WFCB-P400 versions (NSF/ANSI 42 and 53), but those are different model numbers, so we do not count them as a listing for WFCB.

Fit note: each replacement above carries the WFCB number in its own model name, so its seller presents it as a replacement for WFCB. We did not confirm fit with the replacement makers; confirm with your manual.

What the tiers mean for WFCB

Most replacement brands sell the same filter shape in up to three versions with almost the same name. For WFCB we found 4 basic, 4 mid and 2 top tier models.

Basic tier, NSF/ANSI 42 only: listed for aesthetic claims such as chlorine, taste and odor. No health claims such as lead.
Mid tier, adds NSF/ANSI 53: health effect claims. Check the listing for the exact contaminants; for these models it includes lead where marked above.
Top tier, adds NSF/ANSI 401: a set of emerging compounds such as some medicines and pesticides, each named in the listing.

The model numbers differ by a letter or a suffix, so read the exact number on the box before you buy. NSF 42 vs 53 vs 401 explained.

Questions

Is a cheap replacement WFCB filter as good as genuine?

It depends on the exact model. Of the 10 replacements we found, 4 are listed to NSF/ANSI 42 only. Top tier models such as EFF-WFCBA and Water Specialist WSWFCB-U are listed to 42, 53 and 401. We could not find a public listing for the genuine filter.

Does the WFCB filter remove lead?

We could not confirm a lead claim for the genuine filter in a public listing. Among replacements, 0 of 10 list lead reduction.

Where do these certification facts come from?

From the public NSF, IAPMO R&T and WQA listings, searched by the exact model number, with the read date shown. A second, separate lookup confirmed each row before publishing. We never call a filter certified unless the listing names that exact model.
