MWFP filter: genuine vs replacement
Last checked October 28, 2026
Either, if you pick a matching tier
The genuine GE MWFP (MWF) is listed to NSF/ANSI 42, 53 and 401 at the exact model level (IAPMO).
We found 32 replacement models listed by number: 7 cover the same standards, and 18 are listed to NSF/ANSI 42 only, which covers taste and chlorine, not lead.
Verdict: either is fine if you pick a matching tier, such as JPR-MWFA, AQUA CREST AQF-MWF-D, Amazon Basics AMZN-MWF-A and 4 more. Skip the basic tiers if you want lead reduction.

GE's MWFP page is titled GE MWF Refrigerator Water Filter, and GE says MWFP is the improved MWF sold since September 2013. IAPMO R&T lists GE's filter under the model name MWF; that listing is shown here. Replacements are sold as MWF replacements for the same reason.
Fit note: each replacement above carries the MWFP number in its own model name, so its seller presents it as a replacement for MWFP. We did not confirm fit with the replacement makers; confirm with your manual.

What the tiers mean for MWFP
Most replacement brands sell the same filter shape in up to three versions with almost the same name. For MWFP we found 18 basic, 7 mid and 7 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 MWFP filter as good as genuine?
It depends on the exact model. Of the 32 replacements we found, 18 are listed to NSF/ANSI 42 only. Top tier models such as JPR-MWFA, AQUA CREST AQF-MWF-D and 5 more are listed to 42, 53 and 401. The genuine filter is listed to NSF/ANSI 42, 53 and 401.
Does the MWFP filter remove lead?
The genuine filter's NSF/ANSI 53 listing includes lead reduction. Among replacements, 14 of 32 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.
