Frigidaire FPPWFU01 Water Filter (PurePour PWF-1) Complete Guide
The Frigidaire FPPWFU01 water filter is the most overlooked replacement in the whole PureSource range. Most owners never learn it exists until their refrigerator refuses the filter they just paid for.
The FPPWFU01, sold under the PurePour PWF-1 product name, is not the most searched or most advertised filter Frigidaire makes. But on the refrigerators it was built for, nothing else will do the job. That is exactly why it matters.
This guide gets straight to the point, whether this filter is the right one for your fridge, what it really costs across its life, and everything worth checking before you install it.
Who Is the Frigidaire FPPWFU01 / PWF-1 Filter For?
The FPPWFU01 is not a universal Frigidaire filter. It is made for a defined range of Frigidaire side by side and French door refrigerators running the PurePour filtration system. If your fridge sits in that group, this is the only OEM filter that will fit and perform the way it should.
You are probably looking for this filter if:
- You own a Frigidaire side by side refrigerator built between 2010 and 2018 and the filter sits in the bottom left grille area, not inside the fridge compartment.
- Your current filter has PWF-1 printed on the label and you want an exact replacement.
- You searched FPPWFU01 or EPFPWFU01 and landed here because the product names made no sense.
- Your Frigidaire refrigerator rejected a filter you were told was compatible.
If any of those match your situation, you are in the right place.
What Does PWF-1 Actually Mean?
The name confusion around this filter is real, and it costs people both time and money. Here is the full picture:
- FPPWFU01 is the official Frigidaire OEM model number. This is what appears in your refrigerator’s owner manual and in the Frigidaire parts catalogue.
- PWF-1 is the PurePour product line name. Frigidaire prints this shorthand on the filter body itself and uses it in many retail listings. Same filter.
- EPFPWFU01 is an alternate listing format you will run into online, mostly on third party retailer sites. Still the same filter, only formatted differently.
Why Frigidaire Uses Multiple Names for the Same Filter
Frigidaire keeps a full part number (FPPWFU01) for catalogue and warranty records, and a shorter consumer facing name (PWF-1) for packaging and shelves. Third party retailers then add prefixes or reformat the number, which makes these look like three separate products. They are not. FPPWFU01, PWF-1 and EPFPWFU01 all point to the same filter.
Always cross check the model number on your current filter against your owner manual before you order. The label inside your filter compartment is the most reliable source you have.

What Does the FPPWFU01 Remove From Your Drinking Water?
The FPPWFU01 uses activated carbon block technology and holds both NSF/ANSI 42 and NSF/ANSI 53 certification. In practice that means it has been independently tested and verified for two separate jobs.
The first job is improving how your water tastes and smells by reducing chlorine and the byproducts left behind by municipal treatment. If your tap water has ever tasted flat, metallic or faintly chemical, that is what NSF 42 filtration deals with.
The second job matters more for health. NSF 53 certification means the filter has been tested to reduce lead by up to 99%, and to remove cysts, specifically Giardia and Cryptosporidium, by up to 99.99%. It also reduces asbestos, mercury, benzene, lindane and fine particulate matter.
Across 200 gallons of filtered water, the FPPWFU01 handles the equivalent of more than 1,500 single use plastic water bottles worth of contamination in your household supply.

Is the FPPWFU01 Compatible With Your Refrigerator?
The FPPWFU01 fits a specific set of Frigidaire side by side and French door models. On these models the filter housing sits at the bottom front grille, a different position from the inside compartment filters used on most other Frigidaire fridges.
| Compatible Frigidaire Models | Compatible Frigidaire Models |
|---|---|
| FGHS2631PF | FGUS2635LE |
| FGHS2631PP | FGUS2635LF |
| FGHS2655PF | FGHS2667KE |
| FGHS2655PP | FGHS2667KP |
| FGHS2644KF | FGHS2679KE |
| FGHS2644KP | FGHS2679KP |
This list covers the most common compatible models. If yours is not here, check the label inside your filter compartment or look at the filter already installed. The model number printed on the filter body is the most reliable compatibility reference there is.
Before You Install the FPPWFU01 | 5 Things to Check First
Unlike inside compartment filters, the FPPWFU01 mounts in the lower grille area of your refrigerator. Two minutes with this checklist prevents the most common installation mistakes.
- Location confirmed? Make sure your filter housing is at the bottom front grille of the fridge, not inside the upper compartment. If it is inside, you have a different filter model.
- Old filter removed correctly? The FPPWFU01 uses a quarter turn counterclockwise release. Do not pull without turning first, forcing it can damage the housing threads.
- O-ring inspected? Before the new filter goes in, check that the rubber O-ring is seated properly. A misaligned O-ring is the number one cause of leaks after installation.
- Cap removed? The new filter ships with a protective cap. Installing it with the cap still on is more common than you would think, and it blocks water flow entirely.
- Ready to flush? Have a container ready for 2 to 3 gallons of water straight after installation. The flush clears air pockets and loose carbon particles from the new filter, and it should never be skipped.
Once installed, press and hold the Filter Reset button on your control panel for 3 seconds to reset the filter indicator light.

The Real Cost of the FPPWFU01 | Per Day and Per Gallon
Most people judge filter cost by the purchase price. The more useful way to look at it is cost per gallon, which turns the number into something you can measure against daily life.
| Cost Comparison | Frigidaire FPPWFU01 (OEM) | Bottled Water (Single-use) | Generic Filter |
|---|---|---|---|
| Cost per unit | ~$40 to $50 | $1 to $2 per bottle (16 oz) | ~$15 to $25 |
| Gallons covered | 200 gallons | 1 gallon per 8 bottles | 200 gallons (claimed) |
| Cost per gallon | ~$0.20 to $0.25 | $8 to $16 per gallon | ~$0.08 to $0.13 |
| NSF 53 certified | Yes | N/A | Not always |
| Daily cost (4 people) | ~$0.22/day | $4 to $8/day | Lower, varies |
OEM vs Generic | Is the Price Difference Worth It?
A genuine FPPWFU01 costs more than a generic compatible filter, and the gap comes down to certification. Generic filters often carry NSF 42 only, which covers taste and odor. The genuine FPPWFU01 carries NSF 53, which covers lead reduction up to 99% and cyst removal up to 99.99%.
For a household with young children, elderly members, or anyone with health sensitivities, the difference between OEM and a non NSF 53 generic is not really a saving, it is a trade off in protection. For a healthy adult household on a tight budget, a verified NSF 53 certified third party option is a reasonable middle ground.
How Long Does the FPPWFU01 Last?
Frigidaire rates the FPPWFU01 at 6 months or 200 gallons, whichever comes first. In most three to four person households using the dispenser as the main water source, those two timelines land close together.
They separate at the extremes. A single person household might reach the 6 month mark having used only 80 gallons, in which case the time limit matters more than the gallon count. A household of six or more can hit 200 gallons in four months, making gallon tracking the measure that counts.
If your water starts tasting off, the dispenser flow slows noticeably, or the indicator light turns amber before the 6 month mark, replace the filter. That is your fridge telling you the media is saturated ahead of schedule.
FAQs
Is FPPWFU01 the same as PWF-1?
Yes. FPPWFU01 is the OEM part number and PWF-1 is the PurePour product name. EPFPWFU01 is a third alternate listing format. All three refer to the same filter.
Where exactly is the FPPWFU01 filter located in my fridge?
On compatible Frigidaire models the filter housing is at the bottom front grille of the refrigerator, not inside the compartment. If yours is inside, you have a different filter model.
Can the FPPWFU01 be used in place of the EPTWFU01 or ULTRAWF?
No. These filters use different housings and installation systems. The FPPWFU01 is not interchangeable with any other Frigidaire filter model.
Why does water taste strange after installing a new FPPWFU01?
The new activated carbon block releases harmless particles during first use. Flush 2 to 3 gallons through the dispenser right after installation and the taste will normalize.
Where can I buy the genuine Frigidaire FPPWFU01 in the USA?
The genuine Frigidaire FPPWFU01 PWF-1 replacement filter is available at discountedfilterstore.com with fast delivery across the USA.
Conclusion
The FPPWFU01 does not get the attention the ULTRAWF or EPTWFU01 gets, but for the refrigerators it fits, it is the only filter that does the job properly. If your fridge uses the PurePour housing at the bottom grille, no other filter will seat, seal or perform the way this one does.
The cost works out to roughly twenty cents per gallon, which makes it one of the cheapest ways to protect your household’s drinking water. Order the genuine FPPWFU01, run the flush, and your fridge takes care of the rest.
