What does a cabin air filter do and when should I replace it?
The cabin filter cleans air entering your car's interior — replace it every 15,000-25,000 miles or sooner if you notice weak airflow or musty odors from the vents.
Clogged cabin filter cuts A/C and heater airflow significantly
Dirty filter allows allergens, dust, and pollutants into the cabin
California wildfire smoke seasons demand more frequent changes
Located behind the glove box on most vehicles — quick replacement
A fresh cabin filter also reduces odors and improves defroster performance
Per HVAC filter standards and manufacturer service intervals.
