The cabin air filter cleans the air you breathe. Many drivers are not even aware that their vehicle is equipped with a cabin filter system.
The cabin air filter, a feature found on most late-model vehicles, cleans the air that comes into the interior through the heating, ventilation and air conditioning system. It catches dust, pollen and other airborne material that can make riding in a car unpleasant, particularly if you have allergies or other respiratory problems. Moving vehicles create a “tunnel effect” that causes pollutants inside the vehicle to reach up to six times the concentration of outside air.
High quality cabin air filters clean the air entering the passenger cabin via HVAC system and have the ability to clean 100 percent of pollutants including pollen and road dust. Some signs that you need a new cabin air filter are reduced air flow through your HVAC system, such as when you crank up the fan too high and you get more noise than results.
We recommend to look at the filter at least once a Year or every 12 to 15,000 miles.
Depending on how long the filter has been in service, you might be shocked at what you see: leaves, twigs, insects, soot and grime that literally cover the entire surface that comes in contact with incoming air you’ll breathe.
