AQI (Air Quality Index) is a tool that lets the public know when air pollution levels may be harmful. When AQI levels rise, the air becomes more polluted and potentially dangerous to your health.
Poor air quality can affect everyone, but it’s especially risky for:
• Children and teens
• Older adults
• People with heart or lung conditions
• Anyone who spends a lot of time outdoors
