Mechanic's tip
Change every 15,000–25,000 miles or once a year. If you notice musty smells from the vents or reduced airflow even on the highest fan setting, the cabin filter is the first thing to check. Many are DIY-accessible behind the glove box in minutes. HEPA-rated filters offer better allergen filtration at only a small price premium. Don't confuse this with the engine air filter — they are completely separate.
