Cabin Air filters are recommended to be replaced every year or 12 to 15,000 miles. These filters get dirty or clogged preventing proper airflow from your heater or A/C blower motor. Poor air flow results in slow defogging or defrosting of windows and eventually a inoperative blower motor from overheating.
