Allergies are nothing to sneeze at. Fortunately, your car can protect you from the pollen, dust and pollutants that are drawn inside through air-conditioning and ventilation systems.
The cabin air filters clean the incoming air, removing allergens. For your part, you should replace these regularly.
“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,” explains Rich White, executive director, Car Care Council—the source of information for the “Be Car Care Aware” campaign promoting the benefits of regular vehicle care, maintenance and repair.
A restricted cabin air filter can cause musty odors in the vehicle and impair airflow in the heating, ventilating and air-conditioning (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 HVAC system.
Cabin air filters should not be cleaned and reinstalled. Instead, they should be replaced every 12,000 to 15,000 miles or per 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 just require your hands.
