The Air Quality Index is a simple system that converts complex air pollution data into an easy-to-understand number. It measures harmful pollutants such as PM2.5, PM10, ozone (O\u2083), nitrogen dioxide (NO\u2082), sulfur dioxide (SO\u2082), and carbon monoxide (CO).<\/p><p data-start=\"1060\" data-end=\"1208\">Even if the air looks clear, invisible pollutants can still be harmful.
