Your Frigidaire refrigerator delivers clean, great-tasting water every day, but only if the right filter is doing the job. If you are looking at the part number FPPWFU01 or the PurePour PWF-1 name and are not completely sure it is the correct replacement for your unit, this guide will walk you through exactly how to check compatibility before buying so you can order with confidence and avoid a costly mismatch.
Why Frigidaire Water Filter Part Numbers Can Be Confusing
Frigidaire has produced multiple refrigerator generations across several series, and different configurations use different water filter formats. Here is why buyers frequently run into confusion when searching for the right replacement:
- Frigidaire makes five different filter technologies — PurePour PWF-1, PureSource 2, PureSource 3, PureSource Ultra, and PureSource Ultra II — and each fits a different set of models
- The technology name and part number both appear in listings so buyers searching PWF-1 and FPPWFU01 may not realize they are looking at the same filter
- Filters look nearly identical across generations making it easy to grab the wrong one based on appearance alone
- All certified Frigidaire filters carry NSF 42 and 53 so certification alone does not tell you which filter fits your specific model
- Some listings bundle multiple part numbers together making it hard to tell which code actually applies to your refrigerator
Where to Find Your Frigidaire Refrigerator Filter Part Number Before Buying
- Check the label on your current filter — the part number is printed directly on it. This is the fastest confirmation you can get
- Look inside the filter housing slot — some Frigidaire models stamp the required part number inside the slot itself
- Find the model plate inside the fridge — usually along the upper door frame or side wall of the fresh food compartment
- Check your user guide — the maintenance section lists the exact replacement filter code for your model
- Search by model number on the retailer page — if the label is worn or unreadable, this is the quickest way to confirm the right filter before you buy
What Is the Frigidaire FPPWFU01 PurePour PWF-1 Water Filter?
The Frigidaire FPPWFU01 is an NSF 42 and 53 certified replacement water filter designed for select Frigidaire refrigerator models. It uses activated carbon block filtration to reduce chlorine taste and odor, lead, heavy metals, VOCs, and sediment before water reaches the dispenser or ice maker. The FPPWFU01 has a service life of 200 gallons or 6 months whichever comes first and uses a twist-in installation design that requires no tools. PurePour PWF-1 is the technology name for this filter and both the FPPWFU01 part number and PWF-1 name refer to the same replacement filter.
What Is the Frigidaire WF3CB PureSource 3 Water Filter?
The Frigidaire WF3CB PureSource 3 is an NSF 42 and 53 certified activated carbon block water filter designed for a different range of Frigidaire refrigerator models with a distinct housing format. It carries the same service life of 200 gallons or 6 months as the FPPWFU01 but uses a different connection design that is not interchangeable with the FPPWFU01 housing. If your refrigerator currently shows WF3CB on the existing filter label, the FPPWFU01 is not the correct replacement for your unit.
What Is the Frigidaire ULTRAWF PureSource Ultra Water Filter?
The Frigidaire ULTRAWF PureSource Ultra is another NSF 42 and 53 certified water filter in the Frigidaire lineup covering a distinct range of compatible models with its own housing format. Like the FPPWFU01 and WF3CB, the ULTRAWF is rated for 200 gallons or 6 months and uses a twist-in installation design, but the housing tolerances are specific to the ULTRAWF and are not compatible with the FPPWFU01 filter housing. Checking the existing filter label rather than relying on the installation type is the most reliable way to confirm which filter your refrigerator requires.
Is the FPPWFU01 the Same as the WF3CB or ULTRAWF?
No. While the FPPWFU01, WF3CB, and ULTRAWF are all NSF 42 and 53 certified activated carbon block filters that serve the same core purpose, they are separate part numbers with different housing designs built for different Frigidaire refrigerator model configurations. Ordering the FPPWFU01 for a refrigerator that requires the WF3CB or ULTRAWF will result in a filter that either does not seat properly or leaves gaps at the housing connection that allow unfiltered water to bypass the filter entirely. Always confirm the part number on the existing filter before placing your order.
Compatibility Checklist Before You Buy the Frigidaire FPPWFU01
- Your current filter label shows FPPWFU01 or PWF-1 — that confirms this is the correct replacement
- Your refrigerator model is on the FPPWFU01 compatibility list — cross-check before ordering
- Your refrigerator is a Frigidaire Gallery or Professional Series model — the FPPWFU01 covers select models in these series
- Your current filter uses a twist-in connection — the FPPWFU01 is twist-in only
- Your current filter does not show WF3CB or ULTRAWF — if it does, those are the correct filters for your unit
- It has been 6 months or 200 gallons since your last replacement — if yes, it is time to order regardless of how the water tastes
Common Mistakes When Buying a Frigidaire Refrigerator Water Filter
- Searching "Frigidaire water filter" without a part number — returns results for multiple incompatible filters
- Mixing up PurePour PWF-1 with PureSource Ultra or PureSource 3 — different technologies, different models, not interchangeable
- Assuming all twist-in Frigidaire filters fit the same housing — they do not. Housing tolerances differ even when the installation style looks the same
- Ordering based on appearance rather than part number — filters from different generations look nearly identical but will not seal correctly in the wrong housing
- Skipping the post-installation flush — always run 2 to 3 gallons through the dispenser after fitting a new filter to clear carbon fines
- Forgetting to reset the filter indicator — the light will trigger a false early reminder if not reset after installation
When Should You Order a Replacement Frigidaire FPPWFU01 Filter?
- 6 months or 200 gallons have passed — replace at whichever comes first
- Water tastes flat or slightly chemical — the carbon block is no longer reducing contaminants effectively
- Ice has a chlorine taste — a reliable sign the filter is past its odor reduction capacity
- Water flow from the dispenser has slowed — a saturated filter restricts flow through the housing
- Ice cubes look cloudy or have a slight colour — sediment the filter can no longer capture is affecting ice clarity
- The filter indicator light has come on — act on it promptly rather than waiting for taste changes to confirm

FAQs
How do I know if my Frigidaire refrigerator needs the FPPWFU01 and not the WF3CB or ULTRAWF?
Check the part number printed on the existing filter currently installed in your refrigerator. That number is the most reliable confirmation of which replacement your unit requires. If the label is unreadable, locate the refrigerator model number inside the fresh food compartment and cross-reference it against the FPPWFU01 compatibility list before ordering.
Can I use the WF3CB or ULTRAWF instead of the FPPWFU01 if they look similar?
No. Despite sharing the same NSF certification levels and service life, the FPPWFU01, WF3CB, and ULTRAWF have different housing designs and are not interchangeable. Using the wrong filter risks an improper seal that allows unfiltered water to bypass the filter at the housing connection.
Do I need to turn off the water supply before replacing the FPPWFU01?
The twist-in housing on the FPPWFU01 is designed for a straightforward swap on most compatible Frigidaire models without requiring the water supply to be shut off. Some minor dripping at the housing during the swap is normal. Consult the Frigidaire user guide for your specific model if you are unsure.
Why does my water still taste off after installing a new FPPWFU01 filter?
Running 2 to 3 gallons through the dispenser after installation flushes carbon fines and trapped air from the new filter and typically resolves any residual taste issues. If off taste persists beyond the flush cycle, confirm the filter is fully locked into the housing and that the filter indicator has been reset.
Is the Frigidaire FPPWFU01 available in a multipack for households that replace filters frequently?
Check the product listing on the shop page for multipack options. Buying in a multipack is a practical option for households that replace the filter at or before the 6 month mark and want to keep a spare on hand to avoid any gap in filtration performance.
Where can I find more detail on how the FPPWFU01 compares to other Frigidaire water filters before I buy?
The Frigidaire FPPWFU01 landing page includes a full head to head comparison table covering the FPPWFU01 against the WF3CB and ULTRAWF side by side to help you confirm the correct filter before ordering.
