OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Mann CU23011 / Mahle LA635

Accuracy note: Covers the Nissan Note (E12 2013-) 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 CU23011, Mahle LA635, Bosch 1987432246, Febi 184011
Activated-carbon version (aftermarket)	Corteco 80001781
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: activated-carbon (charcoal) cabin filters and plain particulate filters are often listed under different part numbers for the Note — the charcoal version costs more but better handles exhaust fumes and odours, so check which type you're replacing.

A Genuinely Important Warning Worth Knowing: UK Guides Can Differ From US Ones — Nissan Note Cabin Air Filter

This is genuinely worth knowing before following any online video: US and other left-hand-drive guides can show a completely different access location from what a UK right-hand-drive car actually has. If you're following a video that doesn't match what you're seeing in your car, a left-hand-drive versus right-hand-drive difference is worth considering before assuming you're doing something wrong.

A genuinely important safety caution worth knowing on related models: on some model years across this range, the airbag on/off switch is located inside the glovebox itself. Take care not to accidentally disturb or disconnect this switch's connector while removing the glovebox for filter access, since doing so can trigger a genuine airbag system fault code that then needs clearing separately.

It's also worth knowing a genuinely practical fitting detail: the replacement filter can be noticeably larger than the opening it needs to pass through — you'll typically need to gently pinch and guide it past the edges of the opening rather than expecting it to slide straight in.

Nissan Note Cabin Air Filter: Easy to Forget, Easy to Fix

There's no performance downside to a neglected Nissan Note cabin filter, which is precisely the problem: nothing about how the car drives will tell you it needs changing, so it often gets forgotten until a musty smell or weak airflow forces the issue.

Nissan Note Cabin Air Filter: What It Does

Don't confuse this with the Nissan Note's engine air filter — they're unrelated parts. The cabin filter's job is cleaning air before it reaches the ventilation system, catching dust and pollen, with activated-carbon versions also filtering some airborne odours.
