ULTRAWF filter: genuine vs replacement

Last checked October 28, 2026

Buy genuine

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

We found 18 replacement models listed by number: 0 cover the same standards, and 16 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 PureSource Ultra, with ULTRAWF 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 ULTRAWF number in its own model name, so its seller presents it as a replacement for ULTRAWF. We did not confirm fit with the replacement makers; confirm with your manual.

What the tiers mean for ULTRAWF

Most replacement brands sell the same filter shape in up to three versions with almost the same name. For ULTRAWF we found 16 basic, 1 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.

Questions

Is a cheap replacement ULTRAWF filter as good as genuine?

It depends on the exact model. Of the 18 replacements we found, 16 are listed to NSF/ANSI 42 only. None we found is listed to NSF/ANSI 401. The genuine filter is listed to NSF/ANSI 42, 53 and 401.

Does the ULTRAWF filter remove lead?

The genuine filter's NSF/ANSI 53 listing includes lead reduction. Among replacements, 2 of 18 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.
