Air Quality Index Definition

The Air Quality Index (AQI) is a measurement scale used to report the levels of common air pollutants in the air. The AQI provides a standardized way of communicating air quality information to the public that is easy to understand and helps people make informed decisions about their health and activities.

The AQI measures 5 common air pollutants that can negatively impact human health:

  • Ground-level Ozone
  • Particulate Matter (PM2.5 and PM10)
  • Carbon Monoxide (CO)
  • Sulfur Dioxide
  • Nitrogen Dioxide
Typically, the AQI ranges from 0 to 500, with higher values indicating poorer air quality. The AQI scale in the US, for example, has 6 categories.
