Frigidaire Refrigerator Water Filter: Which One to Buy, and Which Copies Are Certified
Buy Frigidaire's own filter. For all four of its best sellers, EPTWFU01, PWF-1, ULTRAWF and WF3CB, Frigidaire's filter is certified for lead, and most copies are not certified for lead. The EPTWFU01 also has two copies certified for lead and PFAS, the Electrolux EWF02 (the same filter) and the Instapure REF-IPF-8; their prices are in its table below. Check the number on your old filter.

Look at the model code, not the brand
A copy sold under one brand name can come in two versions that look alike. GLACIER FRESH, for one, has IAPMO R&T listings for lead under "PLUS" codes (GF-EPTWFU PLUS, GF-ULTRAWF PLUS, GF-3CB PLUS). The GLACIER FRESH filters Amazon sells for these fridges carry other codes, and those are certified for taste and odor only, or not at all.
The code is in the Amazon listing's details (model or part number) and on the filter's label. Check it before you buy.
What the certifications mean
- NSF/ANSI 42: chlorine, taste and odor. It says nothing about lead or other health risks.
- NSF/ANSI 53: health. The listing names what was tested, such as lead, cysts or mercury. This is the one to look for.
- NSF/ANSI 401: small traces of some medicines and chemicals, such as ibuprofen and BPA.
- NSF P473: PFOA and PFOS, two PFAS "forever chemicals".

Questions people ask
Which Frigidaire refrigerator water filter do I need?
Read the number on your old filter. The four Frigidaire filters that sell most on Amazon are EPTWFU01 (PureSource Ultra II), FPPWFU01 (PurePour PWF-1), ULTRAWF (PureSource Ultra) and WF3CB (PureSource 3). They fit different fridges and do not swap.
Are cheaper Frigidaire filter copies certified?
Mostly not. For the PWF-1, ULTRAWF and WF3CB we found no copy on Amazon certified for lead; most have no certifier listing at all. For the EPTWFU01, IAPMO R&T lists the Instapure REF-IPF-8 for lead and for PFOA and PFOS; compare its price with Frigidaire's own in the table above.
Do Frigidaire filters remove PFAS?
Two of them do. IAPMO R&T lists the EPTWFU01 and the PWF-1 (FPPWFU01) for PFOA and PFOS on their NSF/ANSI 53 certificate (WP-16165). The ULTRAWF and WF3CB are listed for lead and cysts, not PFAS.
Is EWF02 the same as EPTWFU01?
IAPMO R&T lists the Electrolux PureAdvantage Ultra (EWF02) on the same certificates as the EPTWFU01, with the same claims. Match the number on your old filter before you buy.
How often should I change a Frigidaire fridge filter?
Frigidaire says every 6 months. The certifier rates the EPTWFU01 and PWF-1 for 125 gallons and the ULTRAWF and WF3CB for 200 gallons. The certification holds only for those gallons.
Sources, and what we did and did not check
- IAPMO R&T certificates for Frigidaire's filters (company Electrolux Home Products): WP-14065 (NSF/ANSI 42), WP-16165 (NSF/ANSI 53) and WP-30821 (NSF/ANSI 401), read October 23, 2026 on pld.iapmo.org.

- NSF certified product listings: listings.nsf.org, searched October 23, 2026 for each copy's code. We did not check WQA for these filters.
- Amazon listings and prices: read through Amazon's product API. Prices as of November 12, 2026 at 12:18 PM ET. We show a price only if we read it in the last 24 hours. We match each listing to the certified model code using Amazon's model and part fields.
- We did not: test any filter in a fridge, or check every copy sold (Amazon's search shows us about 30 listings per filter number). Certification covers the model code the certifier lists, for its rated gallons.
