How Does AQI work
The AQI is divided into five categories. Each category corresponds to a different level of health concern. Each category also has a specific color. The color makes it easy for people to quickly determine whether air quality is reaching unhealthy levels in their communities.
Good 0-100
Fair 100-200
Moderate 200-300
Poor 300-400
Very Poor400-500
