What is the Cabin Filter, When to Change It and Why

Model: (Various brands) Various
Part: Cabin air filter

Video tutorial

The cabin filter (or pollen filter) is integrated into the vehicle's ventilation system and is responsible for filtering the air entering the cabin through the air conditioning or heating system. The standard white filter retains dust, pollen, dirt, and suspended particles; the black activated carbon filter also retains odours and harmful gases.

The recommended frequency for changing it is every 15,000 to 20,000 kilometres (approximately once a year). A sign that it is time to change it is air coming from the vents that smells musty; reduced airflow, windows that fog up easily, and generally poor air quality inside the vehicle.
