OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Valeo 715737 / Filtron K1313

Accuracy note: Covers the Seat Ibiza (6J 2008-2017) as listed in the UK aftermarket catalogues. A cabin filter is a cheap part, but it is bought by number, and the number depends on whether your car was built with a standard particulate filter or an activated-carbon one, as well as on trim and build date. The references below are aftermarket catalogue listings for this generation, grouped by brand; the carmaker's own number is not quoted in those listings, so check the genuine filter against your VIN if you want a guaranteed match. Carbon versions carry their own numbers and are listed separately.

Cabin filter, standard (aftermarket)	Valeo 715737, Filtron K1313, Purflux AH889, Hella 8ZC366120-141
Activated-carbon version (aftermarket)	Filtron K 1313A, Purflux AHC889, Hella CF014B
Genuine (OE) number	Not quoted in the catalogue listings — the fitted filter varies by trim and build date, so order the genuine one against your VIN
Fitment notes	Standard and carbon filters have different numbers, and the right size depends on trim and build date. Check which type your car was built with before ordering.

A Genuine Warning: Even Official Guides Can Be Wrong for Newer Models — Seat Ibiza Cabin Air Filter

Worth knowing before following a generic guide: access location and method has genuinely changed between generations on this platform, and it's not just owner confusion — even official manufacturer installation documentation has been confirmed incorrect for newer models in at least one documented case, where a Mann Filter installation guide correctly described the process for an older Ibiza generation but was flagged by multiple owners as simply wrong for the newer, post-2017 model. Older models (broadly pre-2017) are typically accessed behind the glovebox, secured by a small rectangular cover with a few screws; confirm you're following a guide specific to your actual generation before assuming a general "SEAT Ibiza" guide applies.

A genuine, specific spray treatment worth trying for a musty AC smell: a documented, well-corroborated method involves fitting a fresh filter first, then placing an in-cabin AC system treatment canister (such as a Kleen-Air or similar biocide spray) on the back seat, running the fans on full speed with recirculation on, and letting the can discharge fully before continuing to run the fans for a further period. This treats mould and mildew built up through the evaporator and ductwork, not just the filter itself — genuinely worth trying before assuming a fresh filter alone hasn't fully solved a persistent smell.

Seat Ibiza Cabin Air Filter: Easy to Forget, Easy to Fix

Unlike most parts covered on this Seat Ibiza guide, this one has no bearing on how the car drives or performs — its only job is air quality inside the cabin, which makes it very easy to forget about entirely until something forces the issue.

Seat Ibiza Cabin Air Filter: What It Does

The Seat Ibiza's cabin air filter cleans incoming air before it reaches the ventilation system, trapping dust, pollen and, on activated-carbon versions, some airborne odours and pollutants. It has no connection to the engine air filter, which is a completely separate part serving the combustion process rather than the cabin.
