A clean filter means a breath of fresh air.

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 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.

Although hidden, a cabin air filter performs a very important function.  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 from the air that circulates through your cars heating, ventilation and air conditioning (HVAC) system and into the passenger cabin.

To keep air quality at its best, filters should be replaced according to manufacturers’ recommendations, generally once a year or every 15,000 miles/24,000 kilometers – more frequently if you drive in dusty or industrial environments.  Regularly changing cabin air filters also can maximize the life of your cars HVAC system by reducing debris and corrosion on the evaporator core.

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.  Changing a cabin air filter is a quick process on most vehicles, and the cost is minimal.  Ask your AOCA member lube professional if your vehicle needs a cabin air filter change.  You’ll breathe a whole lot easier.
