Air conditioning filter cleaning cycle is one month. Below are the specific details about the car's air conditioning filter: Functions: The air conditioning filter is a filter installed in the car's air conditioning system that can absorb dust particles and protect the air conditioning cooling system, especially during the summer when the air conditioning is frequently used. If the vehicle has been driven for more than 20,000 kilometers, the air filter should be replaced. Installation location: Some air conditioning filters are located under the front windshield of the car, covered by a drainage trough. For most household cars, the air conditioning filter is located in the storage compartment under the front windshield on the passenger side. To access it, simply remove the storage compartment to see the air conditioning filter inside.
