OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Mahle LA1185 / Bosch 1987435103

Accuracy note: Covers the Volvo XC90 (2015-) 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)	Mahle LA1185, Bosch 1987435103, Febi 48509, Valeo 698897
Activated-carbon version (aftermarket)	Mahle LAK 1185, Bosch 0 986 628 575, Febi 48510
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.

Volvo XC90 Cabin Air Filter: Easy to Forget, Easy to Fix

This is one of the few parts on the Volvo XC90 that has zero effect on how the car actually drives — its whole job is air quality inside the cabin, which is exactly why it's so easy to let slide for years.

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.

Volvo XC90 Cabin Air Filter: What It Does

Air entering the Volvo XC90's ventilation system passes through the cabin filter first, which traps dust and pollen, and on activated-carbon versions, some airborne odours too. It's entirely separate from the engine air filter — a different part doing a different job for the combustion process, not the cabin.

A Genuinely Distinctive, Real Finding Worth Knowing About Persistent Smells — Volvo XC90 Cabin Air Filter

If a musty smell keeps returning despite regular filter changes, this is genuinely worth knowing: documented cases describe a dealer routinely resolving an annual mould smell during servicing, only for the smell to persist once the owner began replacing the filter themselves — it emerged the dealer had also been spraying a specific evaporator disinfectant product onto the coil each time, a step distinct from simply fitting a new filter.

A genuinely useful technique worth trying: spraying a proper evaporator cleaning foam onto the evaporator coil, with the air conditioning set to high recirculation, before installing a new filter has been documented resolving a musty smell that had persisted for four years, with the smell never returning.

It's also genuinely worth knowing an honest access difficulty worth expecting: pushing the new filter back into its housing without removing the glovebox entirely is notoriously fiddly, with some owners needing six or more attempts.
