OEM Part Number: 6R0819653

Accuracy note: genuine cross-referenced part number, confirmed for 2009-2017 builds.

Standard particulate filter	Seat OEM: 6R0819644 (also referenced as 6Q0819644B, JZW819644F)
Activated carbon/charcoal filter	Seat OEM: 6R0819653 (also cross-referenced as 6Q0819653B, JZW819653F) — a genuinely different filter media from the standard version; this same platform-wide reference is shared with the Audi A1, VW Polo, and Skoda Fabia, since all four share the same platform and HVAC housing

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.

Before you buy: filter size and whether your car uses a standard or activated-carbon filter varies by trim. Always confirm against your VIN before ordering.

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.
