Frigidaire Refrigerator Water Filters
Frigidaire filter confusion usually comes down to one question: PureSource cartridge or ULTRAWF top-load bay? The push-in PureSource 2 (WF2CB) covers 2,693 models in our fit library; the quarter-twist ULTRAWF seated above it in the cabinet covers another 784.
Type it — e.g. FGHN2866PF1 — and the Filter Finder shows the exact filter for your fridge and its best price. The model plate sits inside the refrigerator compartment, left wall or kickplate area.

Frigidaire Models by Number
Every Frigidaire-family refrigerator model below has a dedicated fit page — exact cartridges that fit, filter location, and change interval. Electrolux twins are filed under their own model strings and resolve to the same bays. The model number is the short alphanumeric string printed on the rating plate inside your fridge (not the serial number). Browse by first character, or jump straight to your model with the Filter Finder.

How to Find Your Frigidaire Model Number
On most Frigidaire units the rating plate is inside the refrigerator compartment — left wall near the crisper drawers, behind the lower kickplate, or on the ceiling of the fresh-food section. The model number is a short alphanumeric code (the longer string is the serial number, which you do not need). Frigidaire strings decode by their opening letters: FRS is the huge side-by-side fleet, FGH and GLH French-door, FFH and FRI top-freezer families. A string opening with EI2 is the Electrolux twin of the same cabinet; numeric strings starting 253 are the Sears catalog code Frigidaire built under. WF2CB, ULTRAWF and similar codes are filter part numbers — those go in the finder, not the A–Z index.
Frigidaire Water Filter FAQ
Location is the fastest tell. A cartridge sliding into the front grille or upper cabinet is the PureSource family — WF2CB on most machines built after 2004, WFCB on older side-by-sides, WF3CB on specific Gallery platforms. A bay you load from the top of the cabinet with a quarter-twist is the ULTRAWF. The Professional series uses the EPTWFU01 housing. 4,130 Frigidaire-family models are mapped in our fit library; type your model number for an exact match.
For refrigerators sold in North America, essentially yes — Electrolux is Frigidaire’s parent company and the Electrolux-badged machines are built on Frigidaire platforms. Electrolux-badge models take the WF2CB PureSource 2 cartridge, the same one their Frigidaire twins use. The practical rule: match by refrigerator model, not by door badge. A few imported Electrolux models use the EWF02 cartridge, which is why the model-number check matters.
It takes the cartridge bay out of the water path so the fridge keeps dispensing with no filter installed. That matters in two situations: while you wait for a replacement cartridge, and when you’d rather run unfiltered than lose water access (some households on pre-filtered supply do this permanently). Frigidaire ships the plug with the machine — usually clipped near the bay or in the owner’s packet. Without a cartridge or the plug seated, most Frigidaire bays dispense nothing at all. If you’ve lost yours, it’s a cheap parts-order item; note that water run through the plug is unfiltered.
Frigidaire rates the PureSource 2 and ULTRAWF cartridges at about 6 months of typical household use; the panel reminder counts down on the calendar, not on actual gallons. Households that run the ice maker hard or live on well water should treat 5 months as the ceiling — carbon exhaust shows up first as chlorine taste in the ice, before the light says anything. Swapping on a fixed date (or on subscription) beats trusting the countdown.
The PureSource line consolidated over the years: the original WF1CB single-stage cartridge family was superseded within the WFCB line, and machines built from the mid-2000s onward standardized on the WF2CB. But same-name generations aren’t automatically cross-compatible — a WFCB bay will not take a WF2CB cartridge, and vice versa. The safe path is searching by refrigerator model number rather than the old part code; the fit library maps 4,130 Frigidaire-family models to the cartridge that actually seats.
Yes — and for Frigidaire it settles the PureSource-vs-ULTRAWF question instantly. Type the number off your old cartridge into the Filter Finder and it reverse-looks-up every Frigidaire-family refrigerator that cartridge fits, Electrolux twins included.
