Maximize the life of your car’s HVAC system.

A cabin air filter is a mechanism that keeps air inside the passenger compartment of your car from becoming stale and unhealthy. Some consumers are not even aware that their car has a cabin air filter. Many newer model cars have the component tucked away inside the dash or elsewhere where it is not easily seen.

Not to be confused with an engine air filter; this piece of equipment removes contaminants such as dust, pollen, mold spores, and other small particles form the air that circulates through your car’s heating, ventilation and air conditioning (HVAC) system and into the vehicle’s passenger cabin. Cabin air filters stop most airborne particles, and some are even capable of eliminating odors. That’s welcome news for people with allergies and others concerned about air quality.

To keep air quality at its best, filters should be replaced according to manufacturer’s recommendations, generally once a year or every 15,000 miles – more frequently if you drive in dusty or industrial environments. Regularly changing cabin air filters also can maximize the life of your car’s HVAC system by reducing debris and corrosion on the evaporator core.

A few signs that your cabin air filter may need to replaced include a visually dirty filter, reduced air flow in the cabin, an increase in cabin noise, or odor in the cabin.
