About the EPA Air Quality Index and Clean Air Campaign Health Advisory



AQI Range EPA Color Scale EPA Descriptor Clean Air Campaign Health Advisory
0 to 50 Green Good The air quality is good and you can engage in outdoor physical activity without health concerns.
51 to 100 Yellow Moderate At this level the air is probably safe for most people. However, some people are unusually sensitive and react to ozone in this range, especially at the higher levels (in the 80s and 90s). People with heart and lung diseases such as asthma, and children, are especially susceptible. People in these categories, or people who develop symptoms when they exercise at "yellow" ozone levels, should consider avoiding prolonged outdoor exertion during the late afternoon or early evening when the ozone is at its highest.
101 to 150 Orange Unhealthy for Sensitive Groups In this range the outdoor air is more likely to be unhealthy for more people. Children, people who are sensitive to ozone, and people with heart or lung disease should limit prolonged outdoor exertion during the afternoon or early evening when ozone levels are highest.
151 to 200 Red Unhealthy In this range even more people will be affected by ozone. Most people should restrict their outdoor exertion to morning or late evening hours when the ozone is low, to avoid high ozone exposures.
201 to 300 Purple Very Unhealthy Increasingly more people will be affected by ozone. Most people should restrict their outdoor exertion to morning or late evening hours when the ozone is low, to avoid high ozone exposures.
Over 300 Black
Hazardous

Everyone should avoid all outdoor exertion.

The Air Quality Index (AQI) has been developed by the Environmental Protection Agency (EPA) to provide accurate, timely, and easily understandable information about daily levels of air pollution. The Index provides EPA with a uniform system of measuring pollution levels for the major air pollutants regulated under the Clean Air Act. Once these levels are measured, the AQI figures are reported in all metropolitan areas of the United States with populations exceeding 200,000.

Index figures enable the public to determine whether air pollution levels in a particular location are Good, Moderate, Unhealthy for Sensitive Groups or worse. In addition, EPA and local officials use the AQI as a public information tool to advise the public about the general health effects associated with different pollution levels and to describe whatever precautionary steps may need to be taken if air pollution levels rise into the unhealthy range.
