WF3CB filter: genuine vs replacement

Last checked October 28, 2026

Buy genuine

The genuine Frigidaire PureSource3 WF3CB is listed to NSF/ANSI 42, 53 and 401 at the exact model level (IAPMO).

We found 15 replacement models listed by number: 0 cover the same standards, and 15 are listed to NSF/ANSI 42 only, which covers taste and chlorine, not lead.

Verdict: buy genuine if you want every listed claim. No replacement we found matches the genuine filter's listings.

IAPMO R&T lists the genuine filter as PureSource3, with WF3CB named as the replacement component. WQA lists it only to a sustainability standard (S-803), which makes no contaminant claims.

Fit note: each replacement above carries the WF3CB number in its own model name, so its seller presents it as a replacement for WF3CB. We did not confirm fit with the replacement makers; confirm with your manual.

What the tiers mean for WF3CB

Most replacement brands sell the same filter shape in up to three versions with almost the same name. For WF3CB we found 15 basic, 0 mid and 0 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.
