The Electrolux UltraFlex ZUF4301OR is a bagless vacuum, but the available documentation does not establish how well it cleans in independent testing. What it does establish is useful for owners: the model has multiple PNC variants, EF129 is identified as its fine-dust filter, and HEPA-filter compatibility should be checked against the appliance’s rating plate before ordering.
What this review can—and can’t—verify
Appliances Online Australia describes the ZUF4301OR as a bagless UltraFlex vacuum and says its sealed filtration system and HEPA filter capture up to 99.99% of dust particles. That figure is a retailer claim; it is not an independently verified test result. No model-specific independent performance testing or reliable long-term owner evidence is established here, so there is no sound basis for a cleaning-performance verdict or a ranking against competing vacuums. Appliances Online Australia’s listing does not state a publication year for the claim.

Check the PNC before buying filters or parts
ZUF4301OR is associated with more than one product number (PNC) in Electrolux’s Italian parts catalog. One catalog entry lists PNCs 90027399401 and 90027396900; a separate ZUF4301OR VACUUM entry lists 90027399400. A model name alone may therefore be insufficient to identify the exact replacement part.
Electrolux says to search for manuals using either the model number or PNC, and notes that the PNC is printed on the appliance rating plate. Find that plate on your vacuum and use its exact number when checking a filter, nozzle, or other part. Electrolux UK’s manual lookup guidance explains the lookup process; the number variants are listed on the Electrolux Italia ZUF4301OR parts page and separate ZUF4301OR VACUUM parts page.

Which filters are documented for the UltraFlex?
EF129 fine-dust filter
Electrolux Germany’s parts catalog identifies the EF129 UltraFlex filter as a fine-dust filter, and the ZUF4301OR-linked instruction-book listing also names EF129. It is the clearest documented filter reference for this model. Confirm the vacuum’s PNC and the part listing before ordering.
HEPA references EFH12W and EFH13W
The shared UltraFlex instruction book names HEPA filter references EFH12W and EFH13W. Because that manual covers several UltraFlex variants, these references do not establish that either filter fits every ZUF4301OR. Check the exact PNC against Electrolux’s parts information before purchase. The manual also says, “Accessories may vary from model to model,” so the exact accessory bundle supplied with every ZUF4301OR variant is not established.

Filter care and manuals
Use the owner’s instructions for filter removal, cleaning, and replacement rather than assuming every UltraFlex variant has identical parts or maintenance details. The instruction-book listing associated with ZUF4301OR identifies EF129 as the fine-dust filter; the shared manual includes filter-care instructions and references EFH12W and EFH13W. Electrolux’s manual lookup accepts a model number or PNC, which is the practical way to find the documentation for your specific appliance.

The available evidence is not enough to make a performance-based recommendation: it does not establish measured pickup, noise, reach, weight, included floor head, exact box contents, or current price and condition. If considering a used or remaining-stock unit, verify the exact PNC, check that the filters and accessories you need can be sourced for that variant, and assess the vacuum’s actual condition. The retailer’s filtration figure alone is not a substitute for independent testing.

Electrolux Australia’s product sheet names the PC91-4IG as replacing the ZUF4301OR in that market. This is a regional successor note, not proof that the newer model is identical or that parts are interchangeable worldwide. A ZE357 compatibility document includes ZUF4301OR among listed models, but treat that as a lead and confirm the precise accessory identity and PNC fit before buying.
