Cabin Air Filter Replacement

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: Cabin air filter

The cabin air filter is located in the engine compartment, just below the windshield: once you open the hood, remove the screws that secure the cover of the cabin air filter container, take it out of its seat, and turn it upside down to extract the old filter; clean the container of any dirt residue and install the new filter, ensuring the correct airflow direction, then reattach it to the vehicle; due to the low cost and the importance of filtering the air entering the cabin, it is not recommended to wash the filter but to always replace it with a new one, preferably one with activated charcoal.
