    What are the common sources of pollution in cars?

    There are many reasons for the poor air inside the vehicle. The most common pollution sources are peculiar smell, cigarette smell, carbon monoxide and other automobile exhaust, carbon dioxide, dust, toxins, pollen, and other particulate matter.
