Air Quality Index (AQI) Overview

The AQI is a tool that indicates how clean - or dirty - the air is and what associated health effects might be a concern for you. The U.S. EPA calculates the AQI for five major air pollutants: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each of these pollutants, EPA has established national air quality standards to protect public health.
