The Frigidaire FPPWFU01 is a genuine OEM PureSource Ultra II refrigerator water filter designed to fit select Frigidaire and Electrolux French door and side-by-side refrigerators manufactured from 2016 onward. It uses a unique twist-in design that replaces the older EPTWFU01/ULTRAWF filters. Always verify your refrigerator model number before purchasing to ensure proper fitment, as the FPPWFU01 is not interchangeable with earlier PureSource filters.

The Frigidaire FPPWFU01 PureSource Ultra II features a 0.5 micron activated carbon block, which is effective at capturing fine particulates and reducing contaminants at a molecular level. It has a rated filtration capacity of 200 gallons or 6 months of use, whichever comes first. Replacing the FPPWFU01 on this schedule ensures optimal flow rate and contaminant reduction performance for your Frigidaire refrigerator.

Yes, the FPPWFU01 is tested and certified to NSF/ANSI Standards 42 (aesthetic effects like chlorine taste and odor), 53 (health-related contaminants including lead, cysts, and select VOCs), and 401 (emerging contaminants such as pharmaceuticals and pesticides). This triple certification makes the PureSource Ultra II one of the most comprehensive filters in the Frigidaire lineup, delivering cleaner, better-tasting water and ice directly from your refrigerator.

To install the FPPWFU01, locate the filter housing inside the refrigerator compartment (typically upper right wall), remove the old filter by twisting it counterclockwise, and insert the new FPPWFU01 by aligning the arrow and twisting clockwise until it clicks into place. After installation, press and hold the "Water Filter" or "Reset" button on your Frigidaire control panel for approximately 3 seconds until the indicator light turns from red to green or blue.

After installing a new Frigidaire FPPWFU01, you should flush approximately 2 to 3 gallons of water (about 5 minutes of dispensing) to purge air from the line and remove any loose carbon fines from the activated carbon block. You may notice cloudy water or sputtering during the first few fills — this is normal and will clear up after flushing. Discard the first two batches of ice as well to ensure your FPPWFU01 delivers clean, great-tasting water at full efficiency.
