Air Quality Index (AQI)

What is the Air Quality Index?

The Air Quality Index (AQI) is a tool for reporting daily air quality. It tells you how clean or polluted your air is and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. It takes all the monitored pollutants and relates them to a single-scale value to indicate air quality. See the AQI guide below for details.
