OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Mann CU1910 / Mahle LA471

Accuracy note: Covers the Hyundai i10 (2014-2019) 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)	Mann CU1910, Mahle LA471, Bosch 1987432164, Febi 24567
Activated-carbon version (aftermarket)	No carbon version listed separately for this generation
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 Genuinely Honest Diagnostic Point Worth Knowing Before Buying Another Filter — Hyundai i10 Cabin Air Filter

If a musty smell persists even after fitting a fresh cabin filter, this is genuinely worth knowing: mould or mildew can develop further downstream, on the evaporator core or within the ducting itself, meaning a new filter alone won't necessarily resolve it. A genuinely practical technique worth trying: with the filter removed, spraying a mould and mildew treatment down through the empty filter slot while running the blower on medium reaches the evaporator directly.

A genuinely useful, real preventative habit worth building: switching off the air conditioning compressor specifically for the last few minutes of a journey, while leaving the blower running on outside air, helps dry out the evaporator coils before the car sits switched off, reducing the chance of mould developing in the first place.

It's also worth knowing that a sudden, noticeable reduction in airflow can occasionally be caused by debris or a rodent nest blocking the air intake at the base of the windscreen.

Hyundai i10 Cabin Air Filter: Easy to Forget, Easy to Fix

This is one of the few parts on the Hyundai i10 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.

Hyundai i10 Cabin Air Filter: What It Does

Air entering the Hyundai i10'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.
