GE Refrigerator Water Filter Replacement: MWF, RPWFE, and XWFE Guide for 2026
GE has produced more refrigerator water filter variants than any other major brand. The MWF was the residential standard for over a decade. The RPWFE arrived for the Profile line in 2016 with NSF 401 certification and an RFID chip. The XWFE arrived in 2019 with PFOA and PFOS reduction added. If you own a GE refrigerator, knowing which of these three cartridges fits is the first step toward water quality that actually matches your refrigerator's design.
This guide breaks down the three current GE cartridges, which refrigerators take each one, how the RFID chip on the RPWFE and XWFE works, and how subscribe-and-save scheduling keeps GE owners ahead of the 6-month replacement cycle.
The Three Active GE Cartridges
| Cartridge | GE Refrigerator Era | NSF Certifications | RFID Chip |
|---|---|---|---|
| MWF | Most production through 2017 | 42, 53 | No |
| RPWFE | Profile and select higher-end (2016-2019) | 42, 53, 401 | Yes (required) |
| XWFE | Newest models (2019+) | 42, 53, 401, P473 | Yes (required) |
The most reliable verification is to pull your current cartridge and read the part number on the label. If you cannot find a clear label, the refrigerator's model number on the inside-door sticker will narrow down which cartridge fits.
GE MWF Water Filter
The MWF is the longest-running GE refrigerator water filter, in continuous production for over 15 years. It fits the majority of GE side-by-side and French-door refrigerators sold from the early 2000s through 2017.
MWF Quick Specs
| Spec | Value |
|---|---|
| OEM part number | MWF (also MWFP and MWFA) |
| Capacity | 300 gallons |
| Replacement interval | 6 months or 300 gallons |
| Connection | Push-and-twist quarter turn |
| Certifications | NSF/ANSI 42 and 53 |
| RFID chip | No |
What the MWF Removes
- Lead (NSF 53)
- Cysts including Cryptosporidium and Giardia (NSF 53)
- Chlorine taste and odor (NSF 42)
- Particulates Class III
- Select VOCs (volatile organic compounds)
The MWF is NSF-certified to 42 and 53. It does not carry NSF 401 certification, which means it has not been tested for pharmaceutical and pesticide reduction. For most municipal water supplies the gap is minor. For households specifically focused on emerging contaminant reduction, the RPWFE or XWFE provides the additional certification layer.
MWF Compatible Models
The MWF fits the majority of GE side-by-side and French-door refrigerators built from approximately 2003 through 2017. Common compatible GE model number prefixes:
- GFE, GFSL, GFSF, GFSS (French-door)
- GSE, GSS, GSH, GSL (side-by-side)
- PFE, PFSF, PFSS (Profile French-door, older)
- ZFGP, ZIBS (Monogram, select models)
The MWF is also sold under MWFP (packaging variant) and MWFA (Amana-branded equivalent). All three are the same physical cartridge.
GE RPWFE Water Filter
The RPWFE arrived in 2016 for GE's Profile line and select higher-end refrigerators. The defining differences from the MWF are NSF 401 certification and an embedded RFID chip required for the refrigerator to function.
RPWFE Quick Specs
| Spec | Value |
|---|---|
| OEM part number | RPWFE |
| Capacity | 170 gallons |
| Replacement interval | 6 months |
| Connection | Twist-on quick-change |
| Certifications | NSF/ANSI 42, 53, and 401 |
| RFID chip | Yes (required) |
What the RPWFE Removes
The RPWFE carries the full NSF 42/53/401 certification profile:
- Lead and mercury (NSF 53)
- Cysts including Cryptosporidium and Giardia (NSF 53)
- Chlorine taste and odor (NSF 42)
- Particulates Class I (NSF 42)
- Pharmaceuticals including ibuprofen, naproxen, atenolol (NSF 401)
- Pesticides and endocrine disruptors (NSF 401)
- Industrial compounds (NSF 401)
For households specifically choosing premium filtration, the RPWFE's NSF 401 certification is the meaningful upgrade over the MWF.
The RFID Chip Explained
The RPWFE has an RFID chip embedded in the cartridge that communicates with the refrigerator to verify cartridge authenticity. When a non-RFID cartridge is installed:
- The water dispenser will not function
- The "Replace Filter" indicator will not clear
- The refrigerator continues to operate normally for cooling and ice production
The chip is mandatory for the water dispenser to work. Genuine GE RPWFE cartridges include the chip. Some aftermarket cartridges include an RFID chip and function normally. Others skip the chip and disable the water dispenser entirely.
For RPWFE-compatible refrigerators, the safest choice is the authentic GE RPWFE or a verified RFID-equipped aftermarket cartridge.
RPWFE Compatible Models
The RPWFE fits GE Profile-line French-door and side-by-side refrigerators built from approximately 2016 through 2019, plus select Monogram models. Common compatible model prefixes:
- PFE, PFSF, PFSS, PYE (Profile French-door)
- PSE, PSS (Profile side-by-side)
- CFE, CFSL (Cafe French-door)
- ZWE, ZWL (Monogram, select models)
GE XWFE Water Filter
The XWFE arrived in 2019 as the replacement for the RPWFE on most new GE models. The defining addition over the RPWFE is NSF P473 certification for PFOA and PFOS reduction.
XWFE Quick Specs
| Spec | Value |
|---|---|
| OEM part number | XWFE |
| Capacity | 170 gallons |
| Replacement interval | 6 months |
| Connection | Twist-on quick-change |
| Certifications | NSF/ANSI 42, 53, 401, and P473 |
| RFID chip | Yes (required) |
What the XWFE Removes
The XWFE carries the same NSF 42, 53, and 401 certifications as the RPWFE, plus NSF P473 certification for:
- PFOA (perfluorooctanoic acid)
- PFOS (perfluorooctane sulfonate)
PFOA and PFOS are perfluorinated chemicals used in firefighting foams and industrial coatings. They have been detected in municipal water supplies in multiple US regions and are a growing concern in residential water filtration. The XWFE is the only standard residential refrigerator water filter currently certified for PFOA and PFOS reduction.
For households specifically concerned about PFAS contamination in their water supply, the XWFE's certification is the meaningful differentiator within the GE lineup.
XWFE Compatible Models
The XWFE fits GE French-door and side-by-side refrigerators built from 2019 forward. Common compatible model prefixes:
- GFE, GFSL (newer French-door, 2019+)
- PFE, PFSF, PYE (newer Profile, 2019+)
- CFE, CFSL (newer Cafe, 2019+)
- GSS, GSH (newer side-by-side, 2019+)
XWFE vs RPWFE Backward Compatibility
GE has stated the XWFE is backward-compatible with most refrigerators originally designed for the RPWFE. Customers with RPWFE refrigerators can upgrade to the XWFE for the additional PFOA and PFOS reduction.
However, the XWFE is not always backward-compatible in practice. Some RPWFE-era refrigerators have firmware that does not recognize the XWFE's RFID chip pattern, and the dispenser will not function. The safest approach is to match the cartridge to the original refrigerator design unless GE specifically confirms XWFE compatibility for your model.
How to Replace a GE Refrigerator Water Filter
The install procedure is similar across MWF, RPWFE, and XWFE. Total time is under two minutes plus a flush.
- Locate the cartridge housing. Upper-right corner of the fresh food compartment on most models, or behind a bottom grille at floor level on some side-by-side models.
- Turn the existing cartridge counter-clockwise approximately a quarter turn. You will feel it release.
- Pull the cartridge straight out. A small amount of water will drip. Have a paper towel ready.
- Remove the new cartridge from packaging. Pull off the protective cap and avoid touching the O-ring with bare hands.
- Insert the new cartridge with the stem oriented correctly. Push gently and rotate clockwise a quarter turn until it locks.
- Reset the filter indicator by holding the "Filter" or "Reset" button on the control panel for 3 to 5 seconds.
- Flush the new cartridge by dispensing approximately 1.5 gallons of water before drinking. The first cup or two may appear cloudy from carbon fines. The cloudiness clears within a minute.
When to Replace a GE Filter
GE specifies replacement every 6 months or at the rated gallon capacity (300 for MWF, 170 for RPWFE and XWFE), whichever comes first. The 6-month calendar interval is the binding constraint for most households.
Signs the cartridge is past due:
- Replace Filter indicator on the control panel
- Reduced flow from the water dispenser
- Returning chlorine taste in filtered water
- Slower ice production
- Cloudy water that does not clear within a minute
Subscribe and Save: The GE Calendar Solution
The GE 6-month replacement cycle pairs well with subscription delivery. Every 6 months, a fresh cartridge arrives a few days before the install date with email reminders if you want them. Skip, pause, or cancel any shipment without penalty.
For households with multiple GE refrigerators (a primary kitchen unit plus a basement or garage refrigerator), coordinated subscription delivery ensures neither cartridge ages past the replacement interval.
Authentic vs Counterfeit GE Cartridges
The MWF, RPWFE, and XWFE are all counterfeited regularly. Ways to verify authentic GE cartridges:
- GE hologram seal on the packaging
- Part number consistency across the cartridge body, the box, and the packaging insert
- NSF certification numbers printed on the packaging
- Purchase from authorized retailers with traceable inventory from GE's distribution network
Counterfeit MWF, RPWFE, and XWFE cartridges fit the housing and produce water. The carbon block in counterfeit cartridges is not NSF-tested, which means you lose the certifications that justify the cartridge price. For households specifically choosing the RPWFE or XWFE for NSF 401 or P473 certification, authentic sourcing is essential.

Frequently Asked Questions
Can I use an XWFE in a refrigerator that originally took an RPWFE?
Sometimes. GE has stated the XWFE is backward-compatible with most RPWFE refrigerators, but some firmware versions do not recognize the XWFE's RFID pattern. The safest move is to match the cartridge to the original refrigerator design unless you have verified compatibility for your specific model.
What is the difference between MWF, MWFP, and MWFA?
All three are the same physical cartridge. MWF is the standard part number. MWFP is a packaging variant. MWFA is the Amana-branded equivalent.
Does the RFID chip on the RPWFE and XWFE actually do anything?
The chip verifies cartridge authenticity to the refrigerator. If a non-RFID cartridge is installed, the water dispenser will not function. The chip also tracks usage for the calendar-based replacement indicator.
Why does my GE refrigerator say "Replace Filter" when I just installed a new cartridge?
The indicator is calendar-based and needs to be reset after installation. Hold the "Filter" or "Reset" button on the control panel for 3 to 5 seconds.
Is the MWF still in production?
Yes. The MWF remains in active production for the large installed base of older GE refrigerators. Replacement cartridges are widely available.
Why do RPWFE and XWFE cartridges cost more than the MWF?
The RPWFE adds NSF 401 certification (pharmaceutical and pesticide reduction). The XWFE adds NSF P473 (PFOA and PFOS reduction). The additional certifications require denser carbon blocks and more thorough manufacturing.
Does the XWFE certification for PFOA and PFOS actually matter for my household?
For households drawing municipal water from regions with documented PFAS contamination (eastern US states, locations near military bases, certain industrial regions), the XWFE's P473 certification is meaningful. The EPA maintains a public database of PFAS detection in US water systems.
