Cabin Air Filter

​

Your vehicle’s cabin air filter protects you and your passengers by removing pollen, dust, bacteria, exhaust, mold spores, and other contaminants from the air that circulates through your vehicle’s heating, ventilation and air conditioning system. This is particularly beneficial for people who suffer from allergies.  When your vehicle is in motion or when the ventilation system is in use, impurities from the outside air are vented into the cabin.

These impurities build up inside your vehicle and create an unhealthy mix of pollutants, pollen, dust, and gases. In fact, pollen and harmful substances inside a vehicle can be up to six times more concentrated than outside.  The cabin air filter provides cleaner air in the cabin of your vehicle by removing these impurities from the incoming air.

 

If a dirty or clogged cabin air filter is not replaced, it can cause musty odors in the vehicle and may even cause corrosion damage to the vehicle’s heating and air conditioning system. A dirty or clogged cabin air filter can also cause contaminants to become so concentrated in the cabin that passengers actually breathe in more pollen, fumes and particles when riding in the vehicle than they would walking down the street.   

Over time, the cabin air filter becomes dirty and clogged. As that happens, the filter becomes less effective at preventing contaminants from entering your vehicle’s ventilation system. This can result in mold, odors and reduced ventilation inside the vehicle.  That’s why it’s important to replace your cabin air filter as recommended by your vehicle’s manufacturer — or sooner, if it’s dirty or clogged.
