Cabin air filters play a critical role in maintaining air quality inside your vehicle. Over time, filters become clogged with dust, pollen, and debris, which can reduce airflow through your HVAC system, cause musty odors, and strain your climate control blower motor. Bosch recommends inspecting cabin air filters at least once a year and replacing them at manufacturer-specified intervals, or more frequently if you drive in heavy traffic or dusty conditions. Signs that your cabin air filter needs replacement include reduced airflow from vents, unusual noises from the HVAC fan, or persistent musty smells in the cabin.
