Filters ensure fresh air in your car and improve comfort. Because they filter out dust, pollen, smoke and other pollutants that freely enter the air in your car, they must be replaced regularly. Generally speaking, they should be replaced after one year of use or every 15,000 kilometers of driving mileage. If you find dust on the inside of your car’s windows, stuffiness in the cab, and air conditioning system failure, you need to check and replace the air conditioning filter.
