AQI categories and what they mean

AQI Categories
 Air quality description
Good (0-50) Air quality is considered satisfactory, and air pollution poses little or no risk.
Satisfactory (51-100) Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Moderate (101-200) Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Poor (201-300) Health alerts for sensitive groups may be issued. The general public may experience health effects.
Very Poor (301-400) Health warnings of emergency conditions. The general public is likely to experience health effects.
Severe (401-500) Health warnings of emergency conditions. Everyone is likely to experience health effects.

How is AQI calculated?
The Air Quality Index is determined by measuring the concentrations of specific air pollutants, such as particulate matter, ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide, using air quality monitors and sensors.
This measurement is usually between 0 and 500, with lower numbers indicating cleaner air and higher numbers suggesting more pollution.
