OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Bosch 1987432190 / Febi 27465

Accuracy note: Covers the Lexus CT200h (2011-) 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)	Bosch 1987432190, Febi 27465, Valeo 715620, Blue Print ADT32514
Activated-carbon version (aftermarket)	Bosch 0 986 628 623, Febi 108322, Blue Print ADJ132518
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.

Lexus CT200h Cabin Air Filter: Easy to Forget, Easy to Fix

On the Lexus CT200h, 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.

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.

Lexus CT200h Cabin Air Filter: What It Does

Every bit of air blown through the Lexus CT200h'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.

A Genuinely Useful Piece of Context Worth Knowing About Preventing Musty Smells — Lexus CT200h Cabin Air Filter

If you're trying to prevent musty smells developing, this is genuinely worth trying: setting the airflow to external or fresh air mode for a few minutes before switching the car off, rather than only doing this after parking, helps dry out condensation trapped in the vents on related Lexus models.

A genuinely honest clarification worth knowing: cleaning the evaporator itself, rather than simply replacing the cabin filter, isn't a simple task, since in most cases the entire dashboard has to be removed to access it.

It's also genuinely worth knowing that a smell isn't always filter or mould-related at all: pets, or even wildlife getting into the car if it's not parked in a garage, can introduce an odour that's easily mistaken for a dirty filter or evaporator issue.
