What level of air quality is dangerous?
How does the AQI work?
| Daily AQI Color | Levels of Concern | Values of Index |
|---|---|---|
| Orange | Unhealthy for Sensitive Groups | 101 to 150 |
| Red | Unhealthy | 151 to 200 |
| Purple | Very Unhealthy | 201 to 300 |
| Maroon | Hazardous | 301 and higher |
What is bad air quality index?
AQI values at or below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is considered to be unhealthy—at first for certain sensitive groups of people, then for everyone as AQI values increase.
