Every one of these brands makes several filters that look nearly identical and are not interchangeable. Ordering by brand name is how people end up with a cartridge that will not seat. Order by part number, every time.
Find your part number first
It is printed on the filter already in your fridge. Pull it out and read it — that is faster and more reliable than any lookup chart.
If the filter is missing, check inside the door frame, behind the bottom grille, or in the upper right of the fridge compartment. Failing that, the model number is on a sticker inside the fridge door and the manual is on the manufacturer’s site.
Which part number belongs to which brand
| Brand | Common part numbers | Where it sits |
|---|---|---|
| Whirlpool (also Maytag, KitchenAid, Amana) | EveryDrop EDR1RXD1 / Filter 1, EDR2RXD1 / Filter 2, EDR3RXD1 / Filter 3, EDR4RXD1 / Filter 4 | Inside fridge, upper right, or base grille |
| GE | MWF, MSWF, RPWFE, XWFE, GXRTDR | Upper right inside, or behind base grille |
| Frigidaire (also Electrolux) | PureSource EPTWFU01, PurePour FPPWFU01 / PWF-1, WF3CB, ULTRAWF | Inside top right, or lower left grille |
| Bosch (also Siemens, Thermador) | UltraClarity BORPLFTR50, BORPLFTR55, 11032531 | Inside fridge, upper left or right |
OEM or compatible?
Third-party filters cost a third of the OEM price and most work fine. Two honest caveats.
Some newer GE and Bosch fridges use a chipped filter that the appliance authenticates. Compatible versions of RPWFE and XWFE in particular can trigger a persistent error or refuse to dispense. If your filter has a small electronic tag on it, buy OEM.
Check the certification. A filter certified to NSF/ANSI 42 only handles taste and chlorine. If you want lead reduction you need NSF/ANSI 53 stated explicitly. Many cheap compatibles claim one and imply the other.

GE MWF Genuine Filter
$32.88
The most common GE filter by a wide margin, and one of the few OEM cartridges priced sensibly. No chip, so compatibles also work here if you prefer.
BORPLFTR55 / BORPLFTR50 Compatible
$51.99
Fits Bosch UltraClarity, replacing BORPLFTR50, BORPLFTR55 and 11032531. Confirm which of the three your fridge takes — they are not all the same length.
PurePour PWF-1 / FPPWFU01 Compatible
$44.66
Replaces Frigidaire FPPWFU01 and PurePour PWF-1, also used across several Electrolux models. Note this is a different fitting from the older EPTWFU01 PureSource.
ICEPURE Compatible Cartridge
$31.44
One of the better-reviewed third-party makers, 4.7 stars across a large number of reviews. Multi-brand fit — read the compatibility list in the listing against your exact part number.

How often to change it
Every six months, or roughly 750 litres, whichever comes first. The indicator light on the fridge is a timer, not a sensor — it does not know anything about your water.
Run three or four litres through after fitting a new one. The black flecks in the first glass are harmless loose carbon, but they taste unpleasant and they will clog an ice maker.
