Abstract
An air cleaning system for a vehicle passenger compartment comprises of a first air cleaner unit and a second air cleaner unit. The first air cleaner unit is arranged to discharge air of the vehicle passenger compartment to the outside of the vehicle and to circulate the air upon cleaning the air. The second air cleaner unit is arranged to inhale outside air into the vehicle passenger compartment upon cleaning the outside air. When the air pollution level in the vehicle passenger compartment is high, the air cleaning system is operated to inhale outside air due to the operation of the second air cleaner unit and to discharge inside air due to the operation of the first air cleaner unit. Furthermore, the first air cleaner unit is formed in a thin-box shape and installed on a rear parcel shelf so as to improve the rearward visibility.
