Air quality index range

What is a good air quality index? How is AQI calculated? An AQI value of 1generally corresponds to the national air quality standard for the pollutant, which is the level EPA has set to protect public health.

AQI values below 1are generally thought of as satisfactory. An air quality index ( AQI ) is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become.
