OEM Part Number: 6R0820367

Accuracy note: this part is genuinely consistent across the range, since it's part of the HVAC system rather than the drivetrain. Arona shares its platform with the current Ibiza.

Standard particulate filter	Seat OEM: 6R0819644 — shared with the current-generation Ibiza and related VW Polo variants
Activated carbon/charcoal filter	Seat OEM: 6R0819653 (also cross-referenced as 6R0820367) — a genuinely different filter media from the standard version

A Genuine Warning: Even Official Guides Can Be Wrong for Newer Models — Seat Arona 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 Arona Cabin Air Filter: Easy to Forget, Easy to Fix

There's no performance downside to a neglected Seat Arona cabin filter, which is precisely the problem: nothing about how the car drives will tell you it needs changing, so it often gets forgotten until a musty smell or weak airflow 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 Arona Cabin Air Filter: What It Does

Don't confuse this with the Seat Arona's engine air filter — they're unrelated parts. The cabin filter's job is cleaning air before it reaches the ventilation system, catching dust and pollen, with activated-carbon versions also filtering some airborne odours.
