OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Febi 32760 / Valeo 715816

Accuracy note: Covers the Hyundai i20 (2014-2020) 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)	Febi 32760, Valeo 715816, Blue Print ADG02557, Filtron K1314
Activated-carbon version (aftermarket)	Filtron K 1314A, Febi 1002030, Blue Print ADBP250143
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 i20 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 i20 Cabin Air Filter: What It Does

Two filters get mixed up constantly on the Hyundai i20: this one cleans air for the cabin ventilation system, catching dust, pollen and (on activated-carbon versions) some airborne pollutants, while the separate engine air filter deals purely with combustion air. They don't share a part number or a purpose.
