Air Quality Awareness Week (April 30 – May 4) is a great opportunity to learn more about how your local air quality may affect your health. You may have heard references to “Code Orange” or “Code Red” air quality days during local weather reports. Air quality assessments are taken from the Air Quality Index (AQI), which indicates how clean or polluted your air is. Poor air quality poses health concerns to everyone, but particularly to children, older adults, and those with health problems. Learn more about the AQI.
