Cabin Air quality is the measure of quality of air within the vehicle. Cabin air quality is not just important for comfort but for safety as well [1]. For decades, scientists have studied the air quality outside of automobiles. The in-cabin microenvironment has become a significant source of exposure to numerous air pollutants, such as particulate matter (PM), volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), carbon monoxide, and nitrogen oxides, etc. [4]. There are various physical parameters such as filters, cabin temperature, air exchange rate, A/C ON or OFF condition and direction of flow of air inside the vehicle cabin, which can affect the cabin air quality and purification time. The air exchange and its rate being of highest importance [2]. The paper consists of various experimental results to check the effect of these parameters in improving the cabin air quality.
