What is Air Quality?

Air quality is measured by a system called Air Quality Index (AQI). It was developed by the Environmental Protection Agency (EPA) to assign a number to the air quality.

 

This system takes four major air pollutants into account, ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The higher the AQI, the greater the level of air pollution.

Understand the Scale

The higher the Air Quality Index (AQI) value, the greater the level of air pollution and the greater the health concern. The AQI is divided into six (6) categories as listed below. Each category corresponds to a different level of health concern.

  • Green – good
  • Yellow – moderate
  • Orange – unhealthy for sensitive groups
  • Red – unhealthy
  • Purple – very unhealthy
  • Maroon – hazardous

The Air Quality Index above is also useful, but only monitors several County-wide sensors.
