What is Air Quality?
“Air quality” refers to the condition of the air within our environment. Good air quality refers to the degree to which the air is clean, clear and free of contaminants such as smoke, dust and smog, among other gaseous impurities in the air. Air quality is determined by evaluating a variety of pollution indicators. Good air quality is a requirement to preserve the exquisite balance of life on earth for humans, plants, animals and natural resources. As such, human health, plants, animals and natural resources are threatened when air pollution reaches high concentrations.
What is Air Quality Index?
The AQI is an index to inform the daily air quality. It tells you how clean or polluted your air is and what health effects may be a concern for you. AQI focuses on the health effects you may experience in a few hours or days after breathing polluted air. The EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground level ozone, particle pollution (also known as particles), carbon monoxide, sulfur dioxide and nitrogen dioxide. For each of these pollutants, EPA has established national air quality standards to protect public health. Ozone at ground level and airborne particles are the two pollutants that represent the greatest threat to human health in this country.
AQI is divided into six categories:
| Air Quality Index (AQI) Values | Levels of Health Concern | Colors |
| When the AQI is in this range: | ..air quality conditions are: | …as symbolized by this color: |
| 0 to 50 | Good | Green |
| 51 to 100 | Moderate | Yellow |
| 101 to 150 | Unhealthy for Sensitive Groups | Orange |
| 151 to 200 | Unhealthy | Red |
| 201 to 300 | Very Unhealthy | Purple |
| 301 to 500 | Hazardous | Maroon |
