What AQI is on an Apple Watch, and how it’s measured

The Air Quality Index is a standard way of reporting air quality used by many government agencies, such as the Environmental Protection Agency in the US.  It’s a numeric scale that goes from 0 to 500, in which the lower the number, the better the air quality. 

The EPA calculates the AQI based on five major air pollutants: ozone, particulates, carbon monoxide, sulfur dioxide, and nitrogen dioxide.

Here are the major AQI categories according to the EPA:

  • 0 to 50. Air quality is considered “good,” and air pollution posts “little or no risk.” This is color coded green.

  • 51 to 100. Air quality is “moderate,” and “there may be a moderate health concern for a very small number of people.” This is color coded yellow.
  • 101 to 150. This range is “unhealthy for sensitive groups.” The EPA says that individuals with lung disease, older adults, and children may be at a greater risk from exposure to ozone. Persons with heart and lung disease may be at greater risk from the presence of particles in the air. This is color coded orange.
  • 151 to 200. This is “unhealthy,” and everyone may experience adverse health effects. This is color coded red.
  • 201 to 300. “Very unhealthy.” This level would trigger a health alert. This is color coded purple.
  • 301 to 500. The EPA calls this “hazardous,” and considers this level an emergency. It is color coded maroon.
