What is AQI?

The AQI is an index for reporting daily air quality.  It tells you how clean or polluted your air is, and what associated health effects might be a concern.  The higher the AQI value, the greater the level of air pollution and the greater the health concern. Canton APC’s continuous PM2.5 and ozone monitors report live data to U.S. EPA’s website to accurately report the AQI to the public.


For more information on the air quality index, please visit U.S. Environmental Protection Agency.
