GE Refrigerator Water Filters: MWF, RPWFE, and XWFE Replacement Guide for 2026
GE Refrigerator Water Filters: MWF, RPWFE, and XWFE Replacement Guide for 2026
GE has produced more refrigerator water filter variants than any other brand. If you own a GE fridge, the first question is always the same: which cartridge does it take? The answer depends on when your refrigerator was made and which line it belongs to.
This guide breaks down the three active GE residential refrigerator water filter cartridges, which GE models fit each one, how to install them, and how to handle the RFID chip complication on newer GE refrigerators.
The Short Answer
| GE Refrigerator Era | OEM Cartridge | RFID Chip? | Replace Every |
|---|---|---|---|
| Older standard models (most production through 2017) | MWF | No | 6 months |
| Profile and select higher-end models (2016 to 2019) | RPWFE | Yes (required) | 6 months |
| Newest GE models (2019 forward) | XWFE | Yes (required) | 6 months |
The most reliable verification is to pull your current cartridge and read the part number on the label. Whatever that label says is what to order.
GE MWF Water Filter
The MWF is the longest-running GE refrigerator water filter. It has been in continuous production for over 15 years and fits the majority of GE side-by-side and French-door refrigerators sold from the early 2000s through 2017.
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
- Chlorine taste and odor (NSF 42)
- Lead (NSF 53)
- Cysts including Cryptosporidium and Giardia (NSF 53)
- Particulates
- VOCs (volatile organic compounds)
The MWF is NSF-certified to 42 and 53, which covers most of the contaminants that matter in municipal water. 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.
MWF Compatible Models
The MWF fits the majority of GE side-by-side and French-door refrigerators built from approximately 2003 through 2017, plus selected newer models that did not move to the RPWFE or XWFE platform.
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)
If your GE refrigerator was made before 2017 and your current cartridge says "MWF" on the label, you have a match.
The MWF is also sold under the variant codes MWFP (with a different packaging configuration) and MWFA (Amana-branded equivalent). All three are the same physical cartridge.
GE RPWFE Water Filter
The RPWFE was introduced for GE's Profile line and select higher-end refrigerators starting around 2016. The defining feature compared to the MWF is the RFID chip embedded in the cartridge.
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
- Chlorine taste and odor (NSF 42)
- Lead, mercury, and cysts (NSF 53)
- Pharmaceuticals and emerging contaminants (NSF 401)
- Particulates
- VOCs
The RPWFE was the first GE refrigerator cartridge with NSF 401 certification. The pharmaceutical and pesticide reduction is meaningful in dense urban municipal water supplies where treatment plant outflow can carry low concentrations of compounds like ibuprofen, atenolol, and BPA.
The RFID Chip on the RPWFE
The RFID chip embedded in the RPWFE cartridge communicates with the refrigerator to verify cartridge authenticity. When a non-RFID cartridge is installed, the water dispenser will not function and the "Replace Filter" indicator will not clear.
This is the most common point of confusion for GE customers. The chip is mandatory for the cartridge to work. Genuine GE RPWFE cartridges have the chip built in. Some aftermarket "RPWFE-compatible" cartridges include the chip and work normally. Other aftermarket cartridges skip the chip and disable the water dispenser entirely.
If you are buying an aftermarket RPWFE replacement, verify the listing explicitly states "RFID chip included" or "compatible with GE refrigerators requiring RFID."
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 GE model number 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 is GE's newest residential refrigerator water filter, introduced in 2019. It replaces the RPWFE on most new GE models and offers expanded contaminant reduction.
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 and adds NSF P473 certification for PFOA and PFOS reduction. PFOA and PFOS are perfluorinated chemicals used in firefighting foams and industrial coatings. They have been detected in municipal water supplies in several 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.
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 Compatibility
GE has stated that the XWFE is backward-compatible with 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 move is to stick with the original cartridge type (RPWFE for RPWFE refrigerators, XWFE for XWFE refrigerators) unless GE specifically confirms compatibility for your model.
How to Install a GE Refrigerator Water Filter
The install procedure is similar across MWF, RPWFE, and XWFE. The cartridge sits in either the upper-right corner of the fresh-food compartment or behind the bottom grille, depending on model.
- Locate the filter housing. Upper-right corner of the fresh food section on most models, or behind the bottom grille on some side-by-side models.
- Turn the old cartridge counter-clockwise about a quarter turn. You will feel it release.
- Pull the old cartridge straight out. Expect a small amount of water to drip out. Have a paper towel ready.
- Remove the new cartridge from packaging. Pull off the protective cap. Do not touch the O-ring with bare hands.
- Insert the new cartridge with the stem oriented correctly. Push in gently and rotate clockwise a quarter turn until it locks.
- Reset the filter indicator on the refrigerator control panel. Method varies by model. Typically hold the "Filter" or "Reset" button for 3 to 5 seconds.
- Flush the new cartridge by dispensing about 1.5 gallons of water before drinking. The first cup or two may come out cloudy from carbon fines. That is normal and clears within a minute.
Total time: under two minutes once you have the cartridge in hand, plus the flush.
When to Replace a GE Refrigerator Water Filter
Every 6 months or at the rated gallon capacity (300 for MWF, 170 for RPWFE and XWFE), whichever comes first.
Signs the cartridge is past due:
- Replace Filter indicator on the control panel (turns on at 6 months on a calendar basis)
- Reduced flow from the water dispenser
- Returning chlorine taste in filtered water
- Slower ice production
- Cloudy water that does not clear within a minute of dispensing
Running an exhausted filter does not damage the refrigerator. The filter just stops doing its job and the dispenser delivers near-tap water with residual taste and odor.
Counterfeit GE Cartridges: How to Spot Them
The MWF, RPWFE, and XWFE are all counterfeited regularly. A few ways to verify you have a genuine GE cartridge:
- 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 (NSF 42 and 53 for MWF, plus NSF 401 for RPWFE, plus NSF P473 for XWFE)
- Buy from authorized retailers with traceable inventory direct 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 contaminant reduction certifications that justify the cartridge price.

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. Any of the three works in an MWF-compatible refrigerator.
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 to support the calendar-based replacement indicator.
My GE refrigerator says "Replace Filter" but my cartridge is only 3 months old. What is going on?
The indicator is calendar-based on most GE models. If you installed a new cartridge and the indicator was already on, it may not have been reset. Hold the "Filter" or "Reset" button for 3 to 5 seconds.
Is the MWF still in production?
Yes. The MWF remains in active production by GE for the large installed base of older GE refrigerators. Replacement cartridges are widely available.
Can I install a GE cartridge without tools?
Yes. All three GE cartridges (MWF, RPWFE, XWFE) use quick-change designs that require no tools. The full swap takes under two minutes.
Why do RPWFE and XWFE cartridges cost more than the MWF?
The RPWFE and XWFE carry NSF 401 certification (pharmaceutical and pesticide reduction) that the MWF does not. The XWFE adds NSF P473 (PFOA and PFOS reduction). The additional certifications require denser carbon blocks and more thorough manufacturing.
