How to Replace the Water Filter on a Frigidaire Refrigerator: Find Your PureSource or PurePour Filter

Frigidaire refrigerators use a PureSource, PureSource Ultra II or PurePour filter, depending on the model. Most sit in the top-right of the fresh-food compartment and lock with a push or a quarter turn. After replacing, flush about 1.5 gallons and reset the filter light. Replace every 6 months, sooner in large households.

Which Water Filter Does My Frigidaire Refrigerator Use?

Your Frigidaire's exact model decides the filter it takes, not the series name printed on the front of the fridge. Two refrigerators sold under the same general line can still ship with different filters depending on the specific model and when it was built, which is exactly why checking your model number, rather than assuming based on how the fridge looks or what it's called in the store, is the reliable first step.

Find your model number

The model number sits on the upper left side wall of the fresh-food compartment on a top-freezer Frigidaire, and on the upper right side on a French door or side-by-side model. Checking the correct wall for your configuration saves time over searching the entire compartment.

Gallery or Professional? The model decides, not the series

"Gallery" and "Professional" name a trim level, not a filter, so two fridges in the same series can still take different filters.

Table 1 shows four Frigidaire models with their confirmed water and air filter, drawn directly from Frigidaire's own model pages.

Table 1. Frigidaire Model to Filter

Not seeing your model? Check the part number on your current filter, or use the Frigidaire replacement filters collection to search by model.

Identify the filter you already have

The clearest way to confirm your filter is the name or part number printed on the cartridge itself, matched against Table 2 below.

Frigidaire Water Filters Compared

Frigidaire sells seven water filters across two generations, and each one has its own install motion, so matching the exact part number matters more than matching the series name. Two filters that look similar in a product photo, or that both carry the general "PureSource" name, can still require entirely different removal and installation motions, which is why Table 2 below treats each of the seven as its own distinct part rather than grouping them by family name alone.

The PureSource family

WFCB, WF2CB and WF3CB are Frigidaire's earlier PureSource filters, each with its own removal method and location.

WFCB (PureSource Plus) and WF3CB (PureSource 3) sit at the back top-right and push to lock. WF2CB (PureSource 2) sits at the front top-right and installs with a slide-and-click motion. ULTRAWF (PureSource Ultra) also sits at the back top-right and pushes to lock.

PureSource Ultra II and PurePour

EPTWFU01 (PureSource Ultra II) pushes in and twists to lock, while FPPWFU01 and FPPWFU02 (PurePour and PurePour Connect) push to release and lock.

EPTWFU01 sits at the back top-right. FPPWFU02 sits at the front top-right. Frigidaire's own support page does not list a location for FPPWFU01; check your manual.

Can I use a different Frigidaire filter?

No. Frigidaire does not publish an interchange statement between any of its filters, so use the exact filter your model lists.

The install motions differ enough between families (push versus twist) that a filter from one family generally won't seat correctly in a housing built for another.

Table 2. Frigidaire Filter Specifications (verified against frigidaire.com and frigidaire.ca)

If your Frigidaire is built on the shared WF2CB platform, our Electrolux filter guide covers the EWF2CBPA cross-reference. If it's a Kenmore built by Frigidaire, see our Kenmore refrigerator filter guide.

Where Is the Water Filter in a Frigidaire Refrigerator?

Most Frigidaire filters sit in the top-right of the fresh-food compartment, either at the back or the front, depending on the exact filter. Knowing which of the two top-right positions your filter uses, rather than assuming every Frigidaire filter sits in the same spot, is what actually narrows down which part you're looking for before you even read a label.

Back top-right, inside the fridge

ULTRAWF, WF3CB, EPTWFU01 and WFCB all install at the back top-right of the fresh-food compartment. This is the more common of the two top-right positions across Frigidaire's lineup, covering four of the seven filters in Table 2.

Front top-right

WF2CB and FPPWFU02 install at the front top-right of the fresh-food compartment instead of the back. If you're looking at the back of the compartment and not finding a filter, checking the front edge of the same top-right area is worth doing before assuming the filter is missing or in a different location entirely.

Base grille on some older models

No current Frigidaire product page lists a base-grille filter location. Some older models are reported to use a base-grille housing; check your owner's manual if your filter isn't in either top-right position above. Since none of Frigidaire's current product documentation confirms this location for any specific model, treat it as a possibility worth ruling out on an older unit rather than a confirmed third option alongside the two top-right positions.

How to Replace a Frigidaire Water Filter

Replacement steps depend on your exact filter: push-to-lock, slide-and-click, push-and-twist, or push-to-release, and each one is different enough that matching the right steps to your filter matters. Confirming which of these four motions applies to your specific filter, using Table 2 above, before you start is what prevents forcing a motion that doesn't match your housing and potentially damaging the filter or the connector.

Before you start

• Turn off the ice maker first if you have an EPTWFU01, per Frigidaire's own instruction sheet.

• Keep a towel handy for minor drips.

• Unwrap the new filter before you start.

• Frigidaire's filter instructions don't require shutting off the water supply, so there's no need to do so.

Push-to-lock filters (ULTRAWF, WF3CB, FPPWFU02)

1. Press the release on the filter housing.

2. Slide the old filter straight out.

3. Remove the protective caps from the new filter.

4. Slide the new filter straight in.

5. Push firmly until it clicks into the locked position.

Slide-and-click filter (WF2CB)

1. Press the release on the filter housing.

2. Slide the old filter out.

3. Align the new filter with the housing.

4. Slide it in until it clicks into place.

Push-and-twist filter (EPTWFU01)

Frigidaire's own instruction sheet for the EPTWFU01 gives these steps:

1. Turn off the ice maker.

2. Rotate the old filter counterclockwise 90° to remove it.

3. Insert the new filter with the grip horizontal.

4. Turn the new filter clockwise 90° until the grip is vertical.

Push-to-release filter (FPPWFU01), and the cup-cover WFCB

FPPWFU01 pushes to release, slides in, and pushes to lock, while WFCB uses a twist-off cup cover instead.

For FPPWFU01: push to release the old filter, slide the new one in, and push until it locks, per Frigidaire's own FPPWFU01 support page.

For WFCB: twist the cup cover to the left and remove it, pull the old filter out, then insert the new filter nozzle-up and reinstall the cover, per Sears PartsDirect.

Table 3. Replacement Quick Reference

After Replacing: Flush and Reset

Flush a new Frigidaire filter, then reset the indicator; both steps are filter-specific, so check your exact part number. Skipping either step doesn't damage anything, but it does mean your first several glasses of water carry trapped air and carbon fines, and your indicator light stays inaccurate until the reset is completed.

How much water to flush

Frigidaire rates a 1.5-gallon flush for both EPTWFU01 (3 to 4 minutes) and FPPWFU01 (about 3 minutes).

Table 4. Flush by Filter

Frigidaire's general Prime and Purge guide also notes that air in the line can cause 2 to 3 empty ice cycles before ice production returns to normal.

How to reset the water filter light

On PureSource Ultra II and Professional models, hold the Water Filter button for 3 seconds until the indicator changes from red to green.

On menu-style displays, use the display's Options menu and check your manual for the filter item, since Frigidaire doesn't publish one universal sequence for every display type. For the separate air filter light, see our air filter reset guide; that guide covers the air filter only, not the water filter.

How Often to Replace a Frigidaire Water Filter

Replace a Frigidaire water filter every 6 months, sooner if your household is large, since a bigger household reaches a 125-gallon filter's capacity faster. The 6-month figure is a ceiling, not a guarantee; it assumes an average rate of water and ice use, and households that draw more water than average will use up a filter's rated gallon capacity well before the 6-month mark arrives.

Every 6 months, sooner in big households

Frigidaire's own household-size table for its 125-gallon filters shows the replacement interval shrinking as household size grows.

Table 5. Household Size vs. Replacement Interval (125-gallon filters, per Frigidaire's EPTWFU01 page)

This table applies specifically to Frigidaire's 125-gallon filters (EPTWFU01, FPPWFU01, FPPWFU02). The 200-gallon and 400-gallon filters in Table 2 have a higher gallon ceiling, so a given household would generally reach those limits somewhat later than the 125-gallon figures above, though Frigidaire doesn't publish an equivalent household-size table for those filters specifically.

Other times to change it

Change your Frigidaire filter after the refrigerator has sat unused, such as after a move, and always use the same filter type the fridge came with. A filter that's been sitting without water flowing through it for an extended period can start the same way a filter nearing the end of its rated life does, so treating an extended idle period as its own trigger for a fresh filter is a reasonable practice separate from the calendar or gallon count.

Frigidaire Water Filter Troubleshooting

Frigidaire documents specific causes for the most common post-replacement problems, and working through them in order resolves most cases. Rather than assuming a defective filter, ruling out the display lock, an unseated cartridge, and trapped air first, in that order, resolves the large majority of no-water complaints without needing a replacement part at all.

No water after changing the filter

No water after a filter change is most often the display lock, an unseated filter, or air still in the line.

Filter won't lock, leaks or looks damaged

A filter that won't lock, leaks, or looks frozen or cracked needs reseating or replacing, not forcing.

Table 6. Troubleshooting

If flow stays slow after flushing, see our guide to a slow dispenser after a filter change. For trapped air specifically, see how to clear an air lock in the water line.

Frequently Asked Questions

How many gallons does a Frigidaire water filter last?

It depends on the filter. WFCB, WF3CB and ULTRAWF are rated for 200 gallons, WF2CB for 400 gallons, and EPTWFU01, FPPWFU01 and FPPWFU02 for 125 gallons. Check Table 2 for your exact part number, since the ratings vary by filter, not by series.

Do I need to turn off the water to change a Frigidaire filter?

No. Frigidaire's own filter instructions don't call for shutting off the water supply for any current filter. A small amount of water may drip when the old filter comes out, so keep a towel handy.

Is PureSource Ultra II the same as PurePour?

No. PureSource Ultra II (EPTWFU01) pushes in and twists to lock, while PurePour (FPPWFU01) and PurePour Connect (FPPWFU02) push to release and lock. Frigidaire does not list them as interchangeable, so match the exact part number for your model.

Why is my Frigidaire dispenser not working after a filter change?

The most common causes are the display lock being on, the filter not fully seated, or air still in the line. Hold the lock button for 3 seconds to check the display lock first, then reseat the filter and prime the line if water still doesn't flow.

Where is the model number on a Frigidaire refrigerator?

On a top-freezer model, check the upper left side wall of the fresh-food compartment. On a French door or side-by-side model, check the upper right side instead.

Does my Frigidaire have an air filter too?

Some models do. PAULTRA2 and FRGPAAF2 are Frigidaire's air filters, separate from the water filter and replaced on their own schedule.
