## Short answer

The GE MWF is the chip-free twist-in cartridge for GE and Hotpoint refrigerators, and the
numbers MWFP, MWFA, MWFINT and the older GWF are cross-reference names for the same socket
on the resellers' lists, because GE prints no model list and its MWF pages could not be
reached this session. GE's own capacity, interval, flow and certification figures were
therefore not reached either, and NSF's public database returns no listing under GE,
General Electric or Haier. The certified figures belong to the cross-fits: NSF lists
AquaCrest, Amazon Basics, Maxblue, Overbest and Waterdrop MWF cartridges, all made by
Qingdao Ecopure Filter Co., to NSF/ANSI 42 and 53, and five of those SKUs to NSF/ANSI 401
at a 300 gallon service cycle and 0.5 gpm. NSF files the MWF and the RPWFE as separate
trade-name families with no part in common, so the two do not cross. The spec that must
match is the family name printed on the old cartridge, not the gallons.

## Fact sheet

- **Answer:** The GE MWF is GE's chip-free twist-in cartridge for GE and Hotpoint refrigerators, and MWFP, MWFA, MWFINT and GWF are resellers' cross-reference numbers for the same socket. GE's capacity and certification figures were not reachable and NSF's database lists nothing under GE, but it lists AquaCrest, Amazon Basics, Maxblue, Overbest and Waterdrop MWF cartridges to NSF/ANSI 42 and 53, five of them to 401 at 300 gallons and 0.5 gpm.
- **Applies to:** MWF; Number on the old cartridge: MWF, MWFP, MWFA, MWFINT or GWF
- **Compatibility basis:** NSF International's Drinking Water Treatment Units listings for trade name MWF (Standards 42, 53 and 401), GE's genuine-versus-counterfeit support page, and the AquaCrest and GlacierFresh product pages
- **Assumptions:** GE's own MWF spec sheet, capacity, interval, flow and NSF numbers were not reached this session: every GE Appliances and GE Appliance Parts URL returned 403, so no GE figure is printed here.; GE publishes no printed list of refrigerator models for the MWF and routes buyers to a filter-finder tool; the model families on this page are AquaCrest's and GlacierFresh's cross-fit claims, not GE's.; Certifications for AquaCrest, Amazon Basics, Maxblue, Overbest and Waterdrop are NSF database listings by SKU suffix; which suffix a given retail pack contains was not confirmed.
- **Method:** Fit family, cross-reference numbers and certification rows read from NSF's DWTU database and from each cross-fit maker's own product page; the counterfeit signs read from GE's support page. Every figure is a published listing or the maker's spec; nothing was tested.
- **Primary source:** [NSF International, DWTU official listings, trade name MWF (Qingdao Ecopure Filter Co. and others, NSF/ANSI 42)](https://info.nsf.org/Certified/DWTU/listings.asp?TradeName=MWF) (standards or certification body)

If the old cartridge reads RPWFE, leave now: NSF files it as a separate trade-name family with no MWF part in it, and the [RPWFE page](/water/parts/ge-rpwfe-refrigerator-filter/) is the one you want.

## Which GE and Hotpoint refrigerators take the MWF?

GE publishes no printed model list for the MWF and sends buyers to a filter-finder tool, and every GE Appliances and GE Appliance Parts URL tried this session returned 403. The model families below are AquaCrest's and GlacierFresh's cross-fit lists, not GE's, so the number to trust is the one on the old cartridge.

| Number or name | Where it appears | What it means |
|---|---|---|
| MWF | GE's Amazon listing, NSF trade-name index | The current genuine cartridge, sold by GE as a 1-pack; no RFID chip |
| MWFP, MWFA, MWFINT | AquaCrest's and GlacierFresh's cross-reference lists | Numbers resellers list as the same socket; no genuine GE-branded MWFP listing was found on Amazon this session, and NSF's database returns nothing under MWFP or MWFINT |
| GWF, GWF01, GWF06, GWFA | GlacierFresh's cross-reference list | The older GE family the resellers fold into the MWF socket; NSF's database returns nothing under GWF |
| Hotpoint HWF, Kenmore 46-9991 and 46-9996, HDX FMG-1 | AquaCrest's and GlacierFresh's lists | Store-brand numbers the resellers cross to the MWF; GlacierFresh's page adds over 150 GE model numbers behind them |

The MWF is a twist-in cartridge with no chip to read, which is the whole difference from the RPWFE family. GE also sells the XWFE as a separate genuine listing; this page did not check the XWF family against NSF's database, and the XWF and XWFE cartridge has its own page in this wave.

## What else fits the same socket, and which cross-fits does NSF list?

NSF's listing for trade name MWF is the only independent certification on this page. It totals 53 rows across six companies and three standards, 42, 53 and 401. Of those, 37 rows fall under NSF/ANSI 42, with Qingdao Ecopure Filter Co. holding 21. The same factory's AquaCrest, Amazon Basics, Maxblue, Overbest and Waterdrop SKUs appear under NSF/ANSI 53, and five of them under NSF/ANSI 401 at a 300 gallon service cycle and 0.5 gpm.

Every figure in the table is a published listing or the maker's own spec, and nothing was tested here. Certifications read "NSF database" only where the brief recorded the listing; everything else is as stated on the maker's page.

| Cartridge | Capacity and interval | Micron and flow | Certification | What differs |
|---|---|---|---|---|
| GE MWF (genuine) | Not reached | Not reached | No NSF database listing under GE; GE's own claim not reached | The only cartridge with GE's name on it |
| Amazon Basics AMZN-MWF-A, AMZN-MWF-P | 300 gallons on the 401 listing; interval not published | Micron not published; 0.5 gpm | NSF database: 42 and 53 for both, 401 for the -P | The listing sells three tiers under one ASIN; which tier carries which suffix is unconfirmed |
| AquaCrest AQF-MWF (AQF-MWF-D and -P in NSF's database) | 300 gallons; interval not published | Micron not published; 0.5 GPM | Maker's page: 42 and 372; NSF database: -D and -P under 42, 53 and 401 | Sold on aquacrestfilter.com only; no Amazon listing found, so not linked; 33 to 100 F and 20 to 100 psi per its page |
| Waterdrop WDS-MWF, WDP-MWF | 300 gallons on the 401 listing for the WDP | Not published; 0.5 gpm | NSF database: 42 and 53, WDP-MWF also 401 | No WD-MWF product on Waterdrop's site; the Amazon part is named WD-F13, a different model name, so not linked |
| GlacierFresh GF-MWF | 300 gallons or 6 months, and 200 gallons elsewhere on the same page | 0.5 micron; flow not published | Maker's page: an unnumbered "NSF/ANSI, IAPMO, ISO" claim in one place and, elsewhere on the same page, a specific claim of meeting NSF/ANSI 42 and 53; no NSF database entry found under either claim | Its page states it is not sourced by or sponsored by GE |
| Jietai JPR-MWFA, JPR-MWFA-S | 300 gallons on the NSF listing | Not published; 0.5 gpm | NSF database: 42 | Listed under trade name MWFA; no retail listing found |

The Icepure cartridge the brief looked for, RWF1500A, is NSF-listed to 42 under four other company names and none of them is Icepure, and Icepure's live Amazon parts for this socket use different model numbers, so no Icepure part is named as certified here.

## How often does it need replacing?

GE's interval for the MWF was not reached, so this page does not print one. The figures below are the cross-fit makers' and NSF's, and a slowing dispenser is the only early sign any of them names.

| Cartridge | Published interval | Source |
|---|---|---|
| GE MWF | Not reached | No GE document loaded this session |
| Amazon Basics AMZN-MWF-P, Waterdrop WDP-MWF | 300 gallon service cycle | NSF's Standard 401 listing |
| AquaCrest AQF-MWF | 300 gallons | AquaCrest's product page |
| GlacierFresh GF-MWF | 6 months, and both 300 and 200 gallons on one page | GlacierFresh's product page |

GlacierFresh's two capacities contradict each other on one page, so neither is printed as the figure; the 6 month line is its only unambiguous interval.

## How do you spot a counterfeit MWF?

GE's support page on genuine versus counterfeit filters is GE's only published check, it covers every GE filter, and it names no models. Among the characteristics it lists for a counterfeit are misleading and fraudulent labels that violate trademarks, and false claims to meet NSF/ANSI drinking water treatment standards. Separately, the same page notes that counterfeits typically reduce chlorine taste and odor only, with no certification for [lead](/water/guides/lead-in-tap-water-service-line/), mercury or arsenic, and have a record of bursting or leaking, in GE's words.

The NSF database is the check GE's page implies: a cross-fit that prints "NSF certified" without a standard number and without a row under trade name MWF has only its own word.

**Which one to buy**

The genuine GE MWF is the only cartridge here with GE's name on it, and it is also the only one on this page with no certification this session could find: GE's documents were unreachable and NSF's database lists nothing under GE.

The Amazon Basics cartridge is the reverse: NSF lists its AMZN-MWF-A and AMZN-MWF-P to 42 and 53, the -P to 401 at 300 gallons, and the listing sells three tiers under one ASIN without saying which tier carries which suffix.

Buy neither until you have read the old cartridge: an MWF socket takes either, an RPWFE socket takes neither, and the family name decides the purchase.

## The picks

- **GE MWF genuine (1-pack)**: The genuine part, if you want GE's name and warranty (GE's capacity, interval and NSF numbers not reachable this session; no NSF database listing under GE; sold as a 1-pack) Amazon: https://www.amazon.com/dp/B000AST3AK/?tag=ownerspec-20
- **Amazon Basics MWF-compatible (3-pack)**: The NSF-listed cross-fit, if you check the suffix (AMZN-MWF-A and AMZN-MWF-P listed by NSF to 42 and 53, the -P also to 401 at 300 gallons and 0.5 gpm; the listing sells three tiers and the suffix per tier is unconfirmed) Amazon: https://www.amazon.com/dp/B07CH3BWJ2/?tag=ownerspec-20
- **GlacierFresh GF-MWF (4-pack)**: Multipack, if you accept a claim NSF does not list (6 months, 0.5 micron per its page, which prints both 300 and 200 gallons; claims NSF/ANSI 42 and 53 in one place and an unnumbered NSF/ANSI, IAPMO, ISO in another, with no NSF database entry found) Amazon: https://www.amazon.com/dp/B09TKNCSVS/?tag=ownerspec-20

## Frequently asked questions

### Is the GE MWF filter NSF certified?

Not in NSF's public database as of 2026-09-13. Searches of NSF's Drinking Water Treatment Units listings by company (GE, General Electric, Haier) and by trade name (MWFP, GWF, MWFINT) each returned no matching products, and GE's own MWF pages could not be reached. This page therefore prints no standard for the genuine cartridge; the NSF-listed parts are the cross-fits.

### Which cross-fit MWF cartridges are actually NSF certified?

NSF's listing for trade name MWF under Standard 53 names AquaCrest AQF-MWF-P and -D, Amazon Basics AMZN-MWF-A and -P, Maxblue MB-MWF-P and -D, Overbest OB-MWF-P and -D, and Waterdrop WDS-MWF and WDP-MWF, all made by Qingdao Ecopure Filter Co. The -D suffixes, AMZN-MWF-P and WDP-MWF also hold NSF/ANSI 401 at 300 gallons and 0.5 gpm.

### How often should the GE MWF be replaced?

GE's own interval was not reachable this session, so this page does not state one. The cross-fit makers print their own figures: AquaCrest's AQF-MWF page says 300 gallons, NSF's 401 listings for the Amazon Basics and Waterdrop parts say a 300 gallon service cycle, and GlacierFresh's GF-MWF page says 6 months but prints both 300 and 200 gallons on one page.

### How does GE say to spot a counterfeit MWF?

GE's support page on genuine versus counterfeit filters names misleading and fraudulent labels and false NSF/ANSI claims among its listed characteristics, then separately notes that counterfeits often reduce chlorine taste and odor only, with no certification for lead, mercury or arsenic, and have a record of bursting or leaking. The page covers all GE filters and names no specific models.

### Does Waterdrop sell a GE MWF replacement filter?

NSF's database lists Waterdrop WDS-MWF and WDP-MWF under trade name MWF, but Waterdrop's own site search returned no product called WD-MWF, and the Waterdrop cartridge sold for this socket on Amazon is branded WD-F13, a different model name from either NSF entry. Whether the WD-F13 is the same certified part was not confirmed, so it is not linked here.
