These people should stay indoors while smoke levels are high. - Use certified High Efficiency Particulate Air (HEPA) filters in indoor heating, ventilation, cooling and air purification systems. - Avoid using wood-burning stoves and other sources of indoor smoke if possible. DEQs color-coded Air Quality Index provides current air quality conditions and ranks air quality as follows: Green is good. Yellow is moderate. Orange is unhealthy for sensitive groups such as children, the elderly, pregnant women and those with respiratory conditions. Red is unhealthy for everyone. Purple is very unhealthy for all groups.
