Is Your Car Making Your Allergies Worse?

April 24, 2020



Spring is in the air and with it comes pollen, dust and pollutants that are drawn inside vehicles through air conditioning and ventilation systems.  Cabin air filters clean the incoming air , removing allergens, and should be replaced regularly, says the Car Care Council.

“A dirty or clogged cabin air filter can cause contaminants to become so concentrated in the cabin that passengers actually breathe in more fumes and particles when riding in the car than when walking down the street,” said Rich White, executive director, Car Care Council.  “With allergy season upon us, replacing the cabin air filter is a simple way for you and your passengers to breathe easier while you are driving.”

A restricted cabin air filter can cause musty odors in the vehicle and impair airflow in the HVAC system, possibly causing interior heating and cooling problems. Over time, the heater and air conditioner may also become damaged by corrosion.  In addition to trapping pollen, bacteria, dust and exhaust gases, the cabin air filter prevents leaves, bugs and other debris from entering the heating, ventilating and air conditioning (HVAC) system.

Cabin air filters should not be cleaned and reinstalled.  Instead, they should be replaced every 12,000 to 15,000 miles, or according to the owner’s manual.  Most filters are accessible through an access panel in the HVAC housing, which may be under the hood or in the interior of the car.

An automotive service technician can help locate the cabin filter and replace it according to the vehicle’s owner manual.  Some filters require basic hand tools to remove and install the replacement filter while others may just require your hands.
