Air pollution is usually visualized as the black smoke emitted from factories. Little thought is given to tobacco smoke and the by-products of aerosol sprays, paints, cleaners, and pesticides used in the home. We test for Particular Matter (PM 2.5 / 10), Formaldehyde (HCHO), Volatile organic compounds (VOC), Carbon Dioxide (CO2), Carbon Monoxide (CO), Radon Gas (Rn), and much more.
