Also, they can't exactly roll down the windows for fresh air.
Scientists later discovered certain plants would filter the air naturally. These plants are easy to find. I bought two plants at a local garden center yesterday for $10 and they clean my air of benzene, formaldahyde, and trichloroethylene.
