Air Quality Index – What It Is
The AQI is an index 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. The Bureau calculates the AQI for two of the five major air pollutants regulated by the Clean Air Act: ground-level ozone and particle pollution. For each of these pollutants, EPA has established national air quality standards to protect public health. Click here for today's air quality forecast.
