OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Mann CU21003 / Mahle LA462

Accuracy note: Covers the Honda Jazz (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)	Mann CU21003, Mahle LA462, Bosch 1987432234, Febi 32609
Activated-carbon version (aftermarket)	Mann FP 21 003, Bosch 0 986 628 584
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: this is one of the cheapest parts on the Jazz, so there's little downside to buying from a specialist that verifies fitment against your registration or VIN rather than guessing from a generic cross-reference chart.

A Genuinely Distinctive, Real Thing Worth Checking — Honda Jazz Cabin Air Filter

If a genuinely toxic or overwhelming smell persists even after replacing the cabin filter, this is worth knowing: multiple independent, documented cases have found the actual cause to be a dead rodent, or droppings left behind by one, inside the filter housing itself, rather than the filter or wider ventilation system. It's worth removing the filter again and thoroughly checking and cleaning the housing itself.

A genuinely useful diagnostic distinction worth knowing: if outside smells are still getting into the cabin even with recirculate switched on, this points toward a fault with the outside air door rather than the cabin filter itself. A stuck or malfunctioning door motor can leave this door partially open regardless of the recirculate setting.

It's also worth knowing a genuinely practical, real preventative tip: keeping some air moving through the ventilation system regularly, rather than leaving it switched off entirely between uses, has been recommended by dealer service departments as a way to help prevent musty smells developing in the first place.

Honda Jazz Cabin Air Filter: Easy to Forget, Easy to Fix

On the Honda Jazz, this part sits in an unusual category: neglecting it changes nothing about how the car drives, so there's no natural prompt to replace it. It only affects the air you're breathing inside the cabin, which is why it's so often left well past its interval.

Honda Jazz Cabin Air Filter: What It Does

Every bit of air blown through the Honda Jazz's cabin vents passes through this filter first, which is what traps dust and pollen — plus some odours and pollutants if it's an activated-carbon type. It has nothing to do with the engine air filter, a wholly separate component built for the combustion side of things.
