The AQI scale used for indexing the real-time pollution in the above map is based on the latest
reporting formula.
AQI |
Air Pollution Level |
Health Implications |
Cautionary Statement (for PM2.5) |
0 – 50 |
Good |
Air quality is considered satisfactory, and air pollution poses little or no risk |
None |
51 -100 |
Moderate |

Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. |
151-200 |
Unhealthy |
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects |
Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion |
201-300 |
Very Unhealthy |
Health warnings of emergency conditions. The entire population is more likely to be affected. |
Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion. |
300+ |
