OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Mahle LA428/S / Bosch 1987435026

Accuracy note: Covers the Vauxhall Grandland X (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)	Mahle LA428/S, Bosch 1987435026, Valeo 715554, Filtron K1227-2x
Activated-carbon version (aftermarket)	Bosch 0 986 628 610, Filtron K 1227A-2x, Valeo 715555
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.

Accuracy note: genuinely worth knowing: some Grandland X variants use a two-piece cabin filter set rather than a single filter, particularly where the car has separate driver/passenger climate zones — ordering just one filter when two are needed is a common mistake.

Vauxhall Grandland X Cabin Air Filter: Easy to Forget, Easy to Fix

This is one of the few parts on the Vauxhall Grandland X 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.

Vauxhall Grandland X Cabin Air Filter: What It Does

Air entering the Vauxhall Grandland X'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.
