What is healthy air?
Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of
50 or below represents good air quality
, while an AQI value over 300 represents hazardous air quality.
