GE SmartWater Filter: Which One Your Fridge Takes

“GE SmartWater” is the name GE gives its whole refrigerator and under-sink filter family — so if you typed “g e smart water filter” into a search box, this is the page that sorts it out. One name covers seven cartridges, and they do not interchange: the number printed on your old cartridge decides which one you need, not the fridge model and not the shape of the housing. This guide covers the full intent in one place — which SmartWater cartridge your GE fridge takes, the honest genuine prices, how to change it, how to reset the light, and the problems that follow a wrong fit — with buy links to the genuine parts we sell.

Which GE SmartWater Filter Does Your Fridge Take?

Start with the cartridge in your hand, not the badge on the door. GE has used five different refrigerator cartridges under the SmartWater name, plus two under-sink cartridges that share the family:

Two replacements to know before you order: the RPWFE replaces the older RPWF, and the XWFE replaces the older XWF — so if your old cartridge reads RPWF or XWF, the “E” version is the current genuine replacement, but only where your fridge specifies it. The under-sink pair — FQK1K for single-stage systems and FQK2J for dual-stage — is covered below. Our GE refrigerator water filter guide covers the whole GE range in the same way.

MWF — The Original SmartWater Cartridge

The MWF is the cartridge behind generations of GE, Hotpoint and Kenmore refrigerators — the white canister at the back of the top shelf area of the fresh-food compartment. Inside is an activated carbon filtration block that takes the chlorine taste and odour out of dispenser water and traps the sediment that turns ice cloudy. It is rated for 300 gallons, about six months in a typical household, and the change is a bare-hands job: twist the old cartridge anti-clockwise, push the new one up and twist clockwise until it seats, flush 1.5 to 2 gallons through the dispenser, discard the first batch of ice, and reset the filter light. The MWF replaces MWF, MWFP, MWFA, GWF, GWFA, GWF06, FXRC, FXRT, MXRC and HXRT — GE renamed this cartridge family several times, and MWFP is simply the newer name for the same cartridge.

GSWF — The Slim One

Not every GE refrigerator has room for a standard-size cartridge, and the ones that do not take the GSWF instead — a slim SmartWater cartridge roughly half the width of a conventional filter, made for GE top-freezer and side-by-side models whose filter space is too tight for anything bigger. The work inside is the same activated carbon block: chlorine taste and odour out, sediment caught before it reaches your glass, for about six months. The caution that saves returns: the GSWF and the standard-width GE cartridges are not interchangeable. A standard cartridge physically will not go into a GSWF housing, and the GSWF does not fit standard housings. Genuine GE GSWF from $37.99. Genuine GE GSWF

MSWF — The Side-by-Side Cartridge

The MSWF is the cartridge behind a long run of GE side-by-side and built-in refrigerators, including selected GE Profile models on the same platforms. It is the same honest formula — an activated carbon filtration block, 300 gallons, about six months — in the housing those models were built around. It replaces MSWF and MSWF3PK, and it is not the same cartridge as the MWF or the GSWF: different housings, different models, so the number on your old label decides. Genuine GE MSWF from $34.99.

RPWFE & XWFE — The RFID Generation

The two newest SmartWater cartridges do a second job besides filtering: each carries an RFID chip the refrigerator reads. The chip verifies the cartridge is genuine, tracks its real working life, and on many models supports leak detection — and refrigerators have been known to warn, or shut off water functions, when a chip-less look-alike is fitted instead. That is why these two are the cartridges you should never substitute in a hurry.

The RPWFE is GE’s premium SmartWater cartridge for Profile and Café refrigerators, rated for 300 gallons over about six months, with advanced filtration that goes beyond chlorine to trace pharmaceuticals and other impurities ordinary cartridges miss. It replaces the older RPWF. Genuine GE RPWFE from $59.99. Our RPWFE water filter guide covers it in full.

The XWFE is the genuine cartridge for GE’s current generation of French-door and side-by-side refrigerators, rated for 170 gallons over about six months. It replaces the older XWF, but the two are not interchangeable on chip models: if your refrigerator specifies XWFE, an XWF or any chip-less cartridge will not be recognised and may trigger warnings or water shut-off. Genuine GE XWFE from $69.99. Our XWFE water filter guide covers it in full. Genuine GE RPWFE Genuine GE XWFE

FQK1K & FQK2J — SmartWater Under the Sink

The SmartWater name also covers GE’s under-sink systems, and here the check is counting cartridge heads under your kitchen sink. One head means a single-stage system — the GX1S01R — and its cartridge is the FQK1K: a twist-on replacement that reduces lead, chlorine taste and odour and sediment, lasts about six months, and changes by hand in minutes with no plumber and no tools. Genuine GE FQK1K from $35.99 — 2-Pack $72.99, 3-Pack $109.99, 4-Pack $146.99.

Two heads side by side means a dual-stage system — the GX1S50R — and its cartridge set is the FQK2J pair: two matched cartridges, changed together, one full change per 2-Pack at $48.99, or two full changes per 4-Pack at $98.99. The pair replaces cartridges labelled FQSLF and FQSVF. The two are not interchangeable: a single-stage system takes the FQK1K and a dual-stage system takes the FQK2J pair, and matching the labels before you order is the ten-second check that prevents a wrong delivery.

Changing a GE SmartWater Filter

The exact spot differs by model — your manual shows it — but the shape of the job is the same for every fridge cartridge in this family. Read the part number off the old cartridge before you throw it away; that number is your order. Twist the old cartridge out (a towel catches the water held in the housing), push the new one in and twist until it locks firmly — a cartridge a quarter-turn short is the classic cause of slow flow and drips after a change. Flush about 2 gallons through the dispenser and discard it, throw away the first batch of ice, then reset the filter indicator: fit first, flush second, reset last. If the filter light stays on after a correct change, our filter light still on after replacing the filter guide walks through the causes in order — and if an XWFE or RPWFE fridge shows a warning with a new cartridge fitted, remove it and re-seat it with a firm twist first, because a partial seat is the usual cause.

Frequently Asked Questions

What is GE SmartWater? The family name GE gives its refrigerator and under-sink water filter cartridges — MWF, GSWF, MSWF, RPWFE and XWFE for fridges, FQK1K and FQK2J under the sink. The part number on your old cartridge decides which one you need.

Is the MWF the same as the MWFP? Yes. MWFP is the newer name for the same cartridge. If your old filter reads MWF or MWFP — or GWF, MWFA, GWF06 or any of the older numbers — the genuine MWF here fits the same housing.

Can I use an XWF instead of an XWFE? No — not in a fridge that specifies XWFE. The XWF is the older, chip-less cartridge for older models. Fit the code printed on your current cartridge: XWFE fridges need the XWFE.

What is the difference between the RPWF and the RPWFE? The RPWFE is the current genuine cartridge and it replaces the RPWF. If your current cartridge or manual shows either number, the RPWFE is the correct genuine replacement.

FQK1K or FQK2J — which is mine? Count the cartridge heads under your sink. One head is a single-stage system (GX1S01R) and takes the FQK1K. Two heads side by side is a dual-stage system (GX1S50R) and takes the FQK2J pair. They are not interchangeable.

How often should I change a GE SmartWater filter? Every six months, or at the rated gallons — 300 for MWF, MSWF and RPWFE, 170 for XWFE — whichever lands first. On RFID models the fridge tracks the life for you; on older models, write the change date on the cartridge label.
