Cabin Air Filter: what it does & when to replace it
The cabin air filter cleans the air entering the passenger compartment through the HVAC system, trapping dust, pollen, and odors. Replacement signs include weak airflow from the vents, a musty smell, or worse allergy symptoms while driving. Most makers recommend replacement every 20,000–30,000 km or once a year. The filter is usually located behind the glovebox or under the dashboard and can often be swapped in a few minutes without tools — one of the most overlooked yet easiest DIY maintenance items.
DIY difficulty: Very easy DIY (often behind the glovebox). Always confirm the correct part for your exact build by VIN before buying.
