Frigidaire FPPWFU01 (PurePour PWF-1) Water Filter: The Complete Guide

The FPPWFU01 is the filter inside most current Frigidaire refrigerators — sold under Frigidaire’s PurePour name as the PWF-1. It is a genuine factory part with a push-to-lock design, and changing it takes about two minutes with no tools and no water shut-off. This complete guide covers everything owners actually get stuck on: confirming the FPPWFU01 is your filter, every part number it answers to, the model series it fits, what it is certified to reduce, the install and reset steps exactly as the manufacturer lays them out, and what the genuine cartridge costs here — plus a straight answer on the genuine-versus-aftermarket question this filter always raises.

What the FPPWFU01 / PurePour PWF-1 Is

The FPPWFU01 is Frigidaire’s genuine OEM refrigerator water filter, built by the factory to fit modern Frigidaire refrigerator systems. Inside is an activated carbon block — the product page notes the carbon is treated at 1000°C to make it highly porous — in a white push-to-lock cartridge measuring 2.3″ × 2.3″ × 9.5″. Key specifications from the product page:

Does It Fit Your Fridge? Check the Label, Then the Series

As always, the label on your current cartridge decides. If it reads FPPWFU01, PWF-1 or EPPWFU01, this is your filter. The product page lists the compatible Frigidaire and Electrolux refrigerator series as:

FRFS2823, GRFS2853, GRFC2353, PRFC2383, PRFG2383, FRSS2323, FRSS2623, GRSS2352 and GRSS2652.

That covers a wide run of current French door and side-by-side models from both brands. If your series is not listed but your old cartridge carries one of the part numbers above, trust the cartridge — series lists are never exhaustive, and the part number on the part you removed is the one fact that cannot be wrong.

Part Numbers the FPPWFU01 Replaces

Frigidaire and its retailers have sold this cartridge under a shelf of numbers. Per the product page’s comparable part numbers, the FPPWFU01 is the correct replacement for:

One caution: the FPPWFU01 is not the same as the older Frigidaire ULTRAWF or the WF2CB — different cartridges, different housings. If your old filter carries one of those names, you need that filter, not this one.

What the Genuine FPPWFU01 Reduces

Per the product page, the FPPWFU01 is tested and fully certified under NSF/ANSI Standards 42 and 53, and removes up to 99% of contaminants, including dangerous cysts, turbidity and sediment, while eliminating the chemical taste and odour of chlorine. The page’s stated reduction figures:

The page’s feature list also includes lead reduction, mercury reduction, BPA reduction and pharmaceutical reduction. And while it does all that, it leaves the beneficial minerals in your water in place — the point of the design is water that comes out tasting like premium bottled water, not water that has been stripped of everything.

Where It Sits and How to Install It

The PWF-1 lives inside the fridge in its push-in housing. The product page’s install steps — note that you do not need to turn the water supply off:

1. Turn off the ice maker. Have a cloth ready for the small amount of water released during the swap.
2. Remove the old filter by pushing firmly on the end/face of the cartridge until it releases, then slide the old cartridge straight out of the housing and discard it.
3. Unpackage the new filter and, using the alignment guide, slide it gently into the filter housing until it stops against the snap-in connector.
4. Push firmly until the cartridge snaps into place — you will hear a distinct click as it engages.
5. Flush the system: press a drinking glass against the dispenser for about 3–4 minutes (approximately 1.5 gallons) to purge trapped air. Sputtering and air spurts during flushing are completely normal.
6. Turn the ice maker back on.
7. Reset the indicator: press and hold the Water Filter reset button on the control panel for 3 seconds. The status display will change from red to green.

That is the whole job. The two steps people skip are the flush (which is why new-filter water sometimes tastes odd for a day) and the reset (which is why the light stays red and owners assume the filter “didn’t work”).

When to Replace It

The product page rates the FPPWFU01 at 125 gallons and recommends changing it every 3 to 6 months for maximum performance and safety. Where you land in that window depends on use: a household running the dispenser and ice maker hard will exhaust 125 gallons well before six months, while a light-use household can ride closer to the calendar limit. Slow flow, returning chlorine taste, or the red status light are all the cartridge asking to retire — an exhausted carbon block stops capturing contaminants while still letting water through, which is the worst of both worlds. For the longer view on what staying on schedule costs across a year, our breakdown of what a genuine fridge filter costs per year does the honest maths.

Genuine FPPWFU01 vs Aftermarket Copies

The product page makes the genuine case bluntly, and it is the correct one for this cartridge: this is a factory part that snaps tightly and safely into place, while lower-grade knock-offs can warp, split, or cause sudden leaks that ruin kitchen floors. Push-to-lock housings are unforgiving of cartridges moulded slightly out of tolerance — a fraction of a millimetre is the difference between a click and a slow drip behind the fridge.

That is why the FPPWFU01 we sell is the genuine Frigidaire part, SKU FPPWFU01, certified under NSF/ANSI 42 and 53. If you are price-shopping copies, at minimum demand the same two certifications in writing from the seller — and weigh the small saving against a part whose entire job is sealing pressurised water inside your kitchen.

The genuine FPPWFU01 is $36.99–$139.99 at Discounted Filter Store depending on pack size — 1, 2, 3 or 4 packs, with multi-packs cutting the per-filter price for households that would rather stock up once.

Frequently Asked Questions

Are FPPWFU01 and PurePour PWF-1 the same filter? Yes. PWF-1 is the PurePour product name; FPPWFU01 is the Frigidaire part number (and the SKU) for the same genuine cartridge. EPPWFU01 is an alternate number for it as well.

How do I know the FPPWFU01 fits my fridge? Check the label on your current cartridge first — FPPWFU01, PWF-1 or EPPWFU01 settles it. The product page also lists compatible Frigidaire and Electrolux series including FRFS2823, GRFS2853, GRFC2353, PRFC2383, PRFG2383, FRSS2323, FRSS2623, GRSS2352 and GRSS2652.

Do I need to turn the water off to change it? No. Per the product page’s install steps, the water supply stays on. Turn the ice maker off, push the old cartridge’s face to release it, slide the new one in until it clicks, then flush for 3–4 minutes.

How do I reset the water filter light? Press and hold the Water Filter reset button on the control panel for 3 seconds. The status display changes from red to green. A new filter does not reset the light by itself.

How long does the FPPWFU01 last? It is rated at 125 gallons, and the recommended replacement cycle is every 3 to 6 months depending on use — sooner if flow slows or the taste changes.

Is the FPPWFU01 the same as ULTRAWF or WF2CB? No. Those are different Frigidaire cartridges for different housings. Match the part number on your old filter exactly.
