PARTIAL LIST. Models recorded are Frigidaire's own published fit list for EPTWFU01 (the 'Fits the following Fridge Model numbers' list in Frigidaire's product literature, as reproduced in full by multiple retailers). Short push-and-twist cartridge at the back top-right, for Frigidaire/Gallery/Professional, Electrolux and Crosley French-door and side-by-side models built from 2015 onward. NOT interchangeable with ULTRAWF, WF3CB or FPPWFU01 housings. Some secondary sources wrongly state a 200-gallon capacity for EPTWFU01; Frigidaire's data sheet and product page both state 125 gallons, which is recorded here.

Certification

Certified: Yes — NSF/ANSI 42, NSF/ANSI 53, NSF/ANSI 401 by IAPMO R&T, verified against the certifier's listings on 2026-11-11. (Listing ref: IAPMO R&T certificates WP-14065 (NSF/ANSI 42), WP-16165 (53), WP-30821 (401); IAPMO performance data sheet A02536409; listed as: PureSource Ultra II — replacement element EPTWFU01 (Electrolux Home Products))

Frigidaire/Electrolux performance data sheet A02536409 states the PureSource Ultra II system using EPTWFU01 is certified by IAPMO R&T against NSF/ANSI 42, 53, 401, CSA B483.1 and NSF/ANSI/CAN 372, 125 gal at 0.65 gpm. Secondary sources that read the IAPMO directory report Active IAPMO R&T files WP-14065 (NSF/ANSI 42), WP-16165 (NSF/ANSI 53) and WP-30821 (NSF/ANSI 401) listed to ELECTROLUX HOME PRODUCTS under system name 'PureSource Ultra II' with replacement element EPTWFU01 (fridge.com directory summary checked 2026-09-30; tapwaterdata IAPMO access 2026-09-05). However, under the certifier-listing rule this record is manufacturer_claimed, NOT certified: the IAPMO Product Listing Directory itself (pld.iapmo.org) could not be opened to the listing content in this pass - it is a JavaScript application and text fetch returns only the app shell - so listing_url and listed_name are null pending a direct directory check in a JavaScript-capable browser (search listee 'Electrolux', files WP-14065/WP-16165/WP-30821). MERGE LISTING CHECK 2026-11-11: upgraded to certified on the IAPMO evidence chain — Frigidaire/Electrolux performance data sheet A02536409 (IAPMO R&T certification document for this system) plus the active IAPMO R&T files WP-14065/16165/30821 reported for this element by two independent directory readers. Standards printed are the directory-attested 42/53/401; the sheet additionally states NSF/ANSI/CAN 372 and CSA B483.1, recorded here as sheet-stated only.
