Air Quality Index And What It Means?

Air quality is measured with the Air Quality Index, or AQI. This index is used to measure and show the  changes in the amount of pollution in the air. The higher the AQI value, the greater the level of air pollution and the greater the health concern. 

Air quality is divided into six categories. Each category has a different color and corresponds to a different level of health concern. The color makes it easy for people to quickly determine whether air quality is reaching unhealthy levels in their communities. There are a variety of apps for your phone, and web pages that provide you with a location based AQI at all times.

Here is a simple guide to understanding the AQI!

GREEN (0-50)  :Air quality is satisfactory, and air pollution poses little or no risk.

YELLOW (51-100) : Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.

ORANGE (101-150) : Members of sensitive groups may experience health effects. The general public is less likely to be affected.

RED (151-200): Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.

PURPLE (201-300) : Health alert: The risk of health effects is increased for everyone.

MAROON (301 or higher) : Health warning of emergency conditions: everyone is more likely to be affected.
