The WF2CB is one of the older Frigidaire filter codes still in active use, and it comes with a few specifics that catch buyers off guard at replacement time. The filter housing position is different from most other Frigidaire systems. The rated capacity is higher than most buyers expect. And the part number overlaps with several Kenmore and Electrolux codes that are functionally the same filter under different names. This post covers what the WF2CB is, how it differs from the WF3CB and EPTWFU01, how to confirm the right fit before ordering, and the most common mistakes buyers make when replacing it.
Why the WF2CB Creates Confusion at Replacement Time
Three things create most of the confusion around the WF2CB.
- First, the filter housing position. Most Frigidaire filters sit at the top right of the fresh food compartment. The WF2CB sits in the front base grille at the bottom of the refrigerator, or in some models at the front top right of the compartment. Buyers expecting to find the filter inside the refrigerator at eye level sometimes spend several minutes looking in the wrong place.
- Second, the rated capacity. Most Frigidaire filters are rated for 200 gallons or six months. The WF2CB is rated for 200 to 400 gallons depending on the variant and source, which creates inconsistency across product listings. The six month replacement schedule is the more reliable benchmark for most households.
- Third, the overlapping part numbers. The WF2CB is functionally equivalent to Kenmore 46-9911, FC-100, NGFC 2000, and several other codes used across Frigidaire, Electrolux, Kenmore, Gibson, Crosley, and White-Westinghouse refrigerators. Buyers searching by model name rather than filter code can land on the wrong listing.
Where to Find Your Filter Part Number Before Ordering
Confirming the correct filter code before ordering avoids the most common replacement mistake. Here is where to look:
Step 1. Locate the filter housing. On most Frigidaire PureSource 2 models, the filter sits in the front base grille at the bottom front of the refrigerator. On some older models, it sits at the front top right of the fresh food compartment.
Step 2. Check the label on the current filter. The part number, WF2CB, WF3CB, or another code, is printed directly on the filter body.
Step 3. If the label has worn off, check the refrigerator model number on the sticker inside the door frame. That model number can be used to cross-reference the correct filter code.
Step 4. If neither is accessible, check the refrigerator use and care manual. The filter part number is listed in the maintenance section.
What Is the Frigidaire WF2CB Filter
The WF2CB is the PureSource 2 replacement water filter for Frigidaire, Electrolux, Kenmore, Gibson, Crosley, and White-Westinghouse refrigerators using the PureSource 2 slide-out filter housing. It uses activated carbon block filtration and is NSF 42 and 53 certified to reduce chlorine taste and odor, lead, cysts, mercury, asbestos, nitrates, and other contaminants. It is rated for 200 to 400 gallons depending on the variant, with a six month replacement schedule as the general guidance.
The installation is a slide-out, push-to-release design. The filter housing is located either in the front base grille or the front top right area of the fresh food compartment depending on the specific model. No tools are required. Before installation, check which detachable face plate applies to the specific refrigerator model, as the WF2CB ships with multiple face plate options.
What Is the Frigidaire WF3CB Filter
The WF3CB is the PureSource 3 replacement water filter for a newer generation of Frigidaire refrigerators. It sits at the back right corner at the top of the fresh food compartment rather than the front base grille position used by most WF2CB housings. The WF3CB measures 9 inches in length and uses NSF 42 and 53 certified activated carbon block filtration rated for 200 gallons or six months.
The WF2CB and WF3CB are not interchangeable. They use different housing positions, different installation designs, and different filter lengths.
What Is the Frigidaire EPTWFU01 Filter
The EPTWFU01 is the PureSource Ultra II filter for Frigidaire French door and side-by-side models produced after 2015. It uses a push-and-twist installation in the upper right corner of the fresh food compartment. It carries NSF 42, 53, and 401 certifications covering a broader contaminant list than the WF2CB. The EPTWFU01 and WF2CB are not interchangeable and use entirely different housing systems.
Is the WF2CB the Same as the WF3CB
No. The WF2CB and WF3CB are separate filters designed for different Frigidaire PureSource system generations. The WF2CB fits the PureSource 2 system with a front base grille or front top right housing position. The WF3CB fits the PureSource 3 system with a back right corner top housing position. They use different housing positions, different installation designs, and different filter lengths.
The part numbers look similar enough that buyers occasionally order one when the refrigerator needs the other. The current filter label is the most reliable way to confirm which code applies before ordering.
Compatibility Checklist Before Ordering the WF2CB
Before placing an order, run through this checklist:
- Confirm the current filter label shows WF2CB, 240396401, 240396404, Kenmore 46-9911, FC-100, or NGFC 2000
- Confirm the filter housing is located in the front base grille or front top right of the fresh food compartment
- Confirm the refrigerator is a Frigidaire, Electrolux, Kenmore, Gibson, Crosley, or White-Westinghouse model using the PureSource 2 system
- Confirm the installation is a slide-out push-to-release design, not a twist-in or push-and-twist design
- If shipping with multiple face plates, confirm which face plate applies to the specific refrigerator model before installation
- If all five points check out, the WF2CB is the correct replacement. If the current filter label shows WF3CB or EPTWFU01, the product pages for those filters cover the correct replacement for those systems.
Common Mistakes When Buying a Frigidaire WF2CB Replacement
- Looking for the filter in the wrong location. Most Frigidaire filters sit inside the fresh food compartment at the top right. The WF2CB on most models sits in the front base grille at the bottom of the refrigerator. Check the use and care manual for the specific housing location before spending time searching in the wrong place.
- Confusing the WF2CB with the WF3CB. Both are Frigidaire slide-out filters but they fit different housing positions and different PureSource generations. The part number on the current filter is the most reliable way to tell them apart.
- Installing with the wrong face plate. The WF2CB ships with multiple detachable face plate options. Before installation, confirm which face plate applies to the specific refrigerator model. Installing with the wrong face plate may affect the seal at the housing connection.
- Skipping the flush after installation. Run water through the dispenser for approximately 3 minutes or 1.5 gallons and discard before drinking. Skipping this step causes cloudy water or an off taste that most buyers mistake for a defective filter.
- Replacing on gallons rather than time. The WF2CB capacity varies across listings from 200 to 400 gallons. For most households, the six month replacement schedule is the more reliable benchmark than tracking gallon count.
When to Replace or Order a New WF2CB Filter
Replace the WF2CB when any of the following apply:
- Six months have passed since the last replacement
- The filter indicator light on the refrigerator panel has activated
- Water picks up a faint chlorine taste or flat odor
- Dispenser flow has slowed noticeably
- Ice is coming out cloudy or with an off smell
- The refrigerator is used by three or more people daily and the last replacement was four to five months ago
The WF2CB is rated for 200 to 400 gallons depending on the variant, with six months as the standard replacement interval. Households with higher daily dispenser use may benefit from replacing closer to the four or five month mark regardless of the gallon rating.

FAQs
Is the WF2CB the same as Kenmore 46-9911?
Yes. The Kenmore 46-9911 is functionally equivalent to the Frigidaire WF2CB. Both fit the same PureSource 2 slide-out housing and deliver the same filtration performance. The different part numbers reflect the different brand labeling applied to the same filter across Frigidaire, Kenmore, and compatible models.
Does the WF2CB fit Electrolux refrigerators?
Yes. The WF2CB fits select Electrolux refrigerators that use the PureSource 2 slide-out filter housing. Electrolux and Frigidaire share parent company ownership and many Electrolux models use the same filter codes. Confirm the refrigerator model number cross-references correctly before ordering.
What is the face plate on the WF2CB and do I need to change it?
The WF2CB ships with multiple detachable face plate options to accommodate different refrigerator models. Before installation, check the use and care manual or the existing filter to confirm which face plate applies to the specific model. Installing with the incorrect face plate may affect how the filter seats in the housing.
Does the WF2CB reduce lead and cysts?
Yes. The WF2CB carries NSF 42 and 53 certifications, independently tested to reduce chlorine taste and odor, lead, cysts including Cryptosporidium and Giardia, mercury, asbestos, and nitrates. Results may vary depending on local water supply conditions.
What happens if the WF2CB is not replaced on schedule?
A saturated WF2CB filter stops reducing contaminants effectively and may start releasing previously trapped particles back into the water. Dispenser flow typically slows as the carbon block saturates. Replacing on the six month schedule maintains consistent filtration performance through the full service life.
