Have you had your favorite repair shop or other service person recommend a cabin air filter and wonder what he or she was talking about? Most vehicles built after 2005 are equipped with a cabin air filter, and it is designed to filter the air you breathe inside the cabin of the vehicle.
Most cabin air filters are designed to filter pollen and dust from the vehicle air conditioning and heating system. Some even have a carbon filter for bacteria and odor. These filters are very similar to the filter you would change every spring and fall in your homes heating and air conditioning system. Everyone that has seen or changed these filters see the contaminants that are stuck on these filters when replaced.
Normal driving conditions through dust, caused by the wind and the smog and exhaust of daily driving, will cause some cabin air filters to get very clogged with pollutants and cause your vehicle’s ventilation system to run very inefficiently. You might even notice the air flow out the vents to be sluggish and/or have a sour smell. This is an alert that you need a checkup or a new cabin air filter.
This filter will not leave you stuck on the side of the road, but it will add comfort and reduce allergens, which is especially important if you suffer from allergies. To find out if your vehicle is equipped with a cabin air filter check with your owner’s manual or talk with our service professional about having your cabin air filter changed.
