No health impacts are expected when air quality is in this range. When AQI levels are 51 to 100, air quality is deemed “moderate,” which means that unusually sensitive people should consider limiting prolonged outdoor exertion. Air quality is designated “unhealthful for sensitive groups” when AQI levels are from 101 to 150. At this level, active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. When AQI levels are between 151 and 200, air quality is deemed “unhealthful.” At this level, active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion. Everyone else, especially children, should limit prolonged outdoor exertion. “Very unhealthful” air quality is declared when the AQI registers between 201 and 300. Active children and adults, and people with respiratory disease,should avoid all outdoor exertion when the AQI is at this level. Everyone else, especially children, should limit outdoor exertion.
