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.
