How We Chose the Best Frigidaire Water Filter
To choose the best frigidaire water filter, we compared filters sold on Amazon in the U.S. on exact part-number fit, NSF/ANSI certifications listed by each brand (42 for taste and odor, 53 for health contaminants such as lead, 401 for emerging contaminants), rated capacity and replacement interval, and owner reviews for leaks, poor fit and slow flow. We separate certified claims from a brand’s own lab testing, and we note that most refrigerator filters do not remove fluoride.
We checked certification claims against the standards published by NSF International and the EPA’s guidance on lead in drinking water, and we encourage readers to look up a filter’s model number in NSF’s or IAPMO’s online listings. Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
How to Choose the Best Frigidaire Water Filter
Identify the generation
Look for ULTRAWF, EPTWFU01, FPPWFU01 (PWF-1), PWF-2 or WF3CB on the old filter.
PurePour Connect
PWF-2 fridges verify genuine filters and may show errors with generics.
Certifications
ULTRAWF lists NSF 42 and 53. Check Frigidaire’s spec sheets for others.
Genuine vs budget
Genuine filters guarantee fit; NSF 42 generics cost less but focus on taste and odor.
Replacement interval
About every six months.
Flush and reset
Flush a few gallons and reset the filter light after installing.
Where the filter lives
ULTRAWF filters usually sit in the upper-right corner of the fresh food section of side-by-sides, while EPTWFU01 and PurePour filters are often in the upper-left or in the ceiling of French door models. Push or twist the old filter to release it, and keep a towel handy for drips.
Signs it is time to change
Slower dispensing, cloudy or off-tasting ice and the filter indicator light are the main signals. If you rarely use the dispenser, still change the filter about every six months, because carbon can harbor bacteria over time.
Tips for Getting the Most From Your Filter
- Match the generation. ULTRAWF to PWF-2.
- Flush after install. Clear air.
- Reset the indicator. Per manual.
- Replace every six months. Mark the date.
