[LaDeclan]

The cabin air filter is located inside the glove compartment in front of the front passenger seat. To replace it, you need to remove the glove compartment, and you will see the cabin air filter inside, usually positioned at the lower left side. Function of the cabin air filter: It filters and absorbs various particles, dust, and harmful substances from the outside air, providing a better driving environment for passengers inside the vehicle. Disadvantages of not having a cabin air filter: It can lead to contamination of the car's air conditioning system, reduced performance of the cooling system, and cause allergic reactions, lung damage, and irritability due to ozone exposure when passengers inhale dust and harmful gases. Additionally, unpleasant odors can affect driving safety.
