About AQI:

  • The Air Quality Index (AQI) is released by the US Environmental Protection Agency (EPA) to give people an idea of whether it’s safe to breathe the air.
  • AQI is based on the levels of five major pollutants regulated by the EPA: ground-level ozone, particulate matter (PM2.5), carbon monoxide, sulfur dioxide, and nitrogen dioxide.
  • AQI measures air quality by placing it on a scale of 0-500, where air quality is regarded as satisfactory if the AQI is under 50.
