What is the Cabin Air Filter?
When you turn on the heat or air conditioner, the air that you get from the car vents initiates from outside the car. The cabin air filter cleans the air before letting it through the heating or air conditioning system.
Bear in mind:
The cabin air filter is different from the air filter. The work of the air filter is to clean the air that goes into the engine to burn fuel. The job of the cabin air filter is to clean the air that you get from the vents inside the car. You may have more than one cabin air filter.
How to Fix:
Remove and change the cabin air filter(s)
Clean out all the debris from the compartment if required.
Follow the manufacturer’s upkeep schedule and change the cabin air filter as commended. If you frequently park your car under a tree or near bushes, cabin air filter(s) will likely suck up debris and leaves, becoming dirtier, faster.
Common signs indicating you may need to change the Cabin Air Filter:
Airflow from the AC vents is low or weak.
Importance of this service:
When you turn on the heat, fan, or air conditioning in your vehicle, the air that comes into the cabin is taken from outside the car. Before passing through your vents it first goes through the cabin air filter, which captures much of the dust, dirt, and harmful pollutants in the air. A working cabin air filter assures that the air coming through your vents is clean. When the cabin air filter stops working, the air that enters your vents is unfiltered and can be harmful to breathe. A dirty cabin air filter also hinders the flow of air to the vents, which will lower the power of your heating or air conditioning system.
