Mist EDR1RXD1 equivalent Refrigerator Water Filter

Don't know your code? It is printed on the old cartridge and usually on a label inside the filter compartment. Match that code to the codes above — this page covers only the cartridge named in its title.

Is EDR1RXD1 NSF/ANSI 42 certified?

Certification answer: no live certifier listing was located for the Mist cartridge; its NSF/ANSI 42 claims rest on the documents labeled below, not a certifier listing. The full certification record, with each claim labeled by the strength of its evidence, follows.

Certifications — documents and listings

• NSF/ANSI 42 — stated by Whirlpool / EveryDrop; this link is the manufacturer's own page, not a certifier listing.Manufacturer's statement
  Mist Filters states on its own product page that this cartridge — Mist's model CWMF001 — is tested and certified by NSF International to NSF/ANSI 42. Mist Filters does hold a block in the NSF International listing, but that block, read in full on 2026-11-06, does not name CWMF001; its models appear there under other CWMF codes. Until CWMF001 appears in the listing, this certification rests on the manufacturer's statement, not on a listing that names the product. This link is Mist's own page, where the claim is made.

A certification counts as listed here only when a certifier's listing names this cartridge or its system. Anything else is labeled above as what it is — a manufacturer's statement or a reproduction. See how to check a cartridge in the NSF listing.

Verdict

Bottom line: The Mist EDR1RXD1 equivalent — Mist's model CWMF001 — is sold as tested and certified by NSF International to NSF/ANSI 42, but CWMF001 does not appear in the NSF listing's Mist Filters block (read in full, 2026-11-06). Until it does, that certification is the manufacturer's claim, not a listing fact — check any cartridge, genuine or third-party, in the listing under its own code before you buy it.

Mist Filters states that its EDR1RXD1 equivalent (model CWMF001) is tested and certified by NSF International against NSF/ANSI 42. The certifier's listing does carry a Mist Filters holder block, but the block names other CWMF model codes, not CWMF001 — so on this page the claim is carried as a manufacturer statement, with the listing linked so you can check it yourself.

What's wrong with EDR1RXD1?

The drawback: Must be replaced on schedule — an overdue cartridge can perform worse than a fresh one — and the certification must be re-verified in the listing because look-alike part numbers exist and model codes move in and out of listings.

Genuine vs third-party notes

Genuine vs certified third-party: certification status in the linked listing — not the box art — is the deciding evidence. A third-party cartridge should be checked in the certifier listing under its own system or element code.

No specific third-party cartridge has been checked for this page yet. When one is, it will be named here with its own listing check and a dated price.

History

• First published: 2026-11-05.
• Last verified: 2026-11-06.
• 2026-11-06 — Mist EDR1RXD1 equivalent: unsupported cost comparison removed: The verdict said this cartridge 'costs more per gallon than uncertified clones.' This site holds no price data for any such clones, so the comparison was unsupported and has been removed. The manufacturer's own dated price for this cartridge ($19.99, checked 2026-11-06) is now shown on the page.
• 2026-11-06 — Mist EDR1RXD1 equivalent: NSF/ANSI 42 certification reclassified — manufacturer statement, not a live listing: This page presented the cartridge's NSF/ANSI 42 certification as found in the certifier's live listing, because the NSF listing carries a Mist Filters holder block. Read in full on 2026-11-06, that block does not name this cartridge: Mist's own product page identifies the model as CWMF001, and CWMF001 does not appear anywhere in the NSF/ANSI 42 listing — the block names other CWMF model codes. The certification is now carried as what the evidence supports: the manufacturer's own statement, with the listing linked so readers can check it themselves. The verdict text, which also called this third-party cartridge 'genuine' and said it is checkable in the listing under its own code, has been rewritten to match.
• 2026-11-06 — Mist EDR1RXD1 equivalent: certification answer named the wrong cartridge: This page's certification answer said the genuine EDR1RXD1 is named in the certifier's live NSF/ANSI 42 listing. That was wrong: the listing names this Mist cartridge (the Mist Filters holder block, under its CWMF model codes); the sentence was built by a template that used the genuine cartridge's part number as the subject on every page, including third-party ones. The template now names the cartridge each page is actually about, and this page's machine-readable data now gives the cartridge's brand as Mist, not Whirlpool / EveryDrop. Found on an independent review of the page, 2026-11-06.
• 2026-11-06 — Mist EDR1RXD1 equivalent: certification link pointed at the listing itself: The certification link pointed at the certifier's generic search page. It now points at the NSF/ANSI 42 DWTU listing itself, where the Mist Filters holder block appears (checked 2026-11-06); the holder's models are listed there under their CWMF codes.
