Air quality measures the cleanliness of outdoor and indoor air, directly dictating how safely you can breathe, exercise, and live. Measured by the Air Quality Index (AQI) on a scale from 0 to 500, air quality reflects the concentration of hazardous gases and microscopic particle pollution ($\text{PM}_{2.5}$) in the atmosphere. Knowing how to interpret these numbers prevents immediate lung irritation and guards against long-term respiratory disease.
How to Check Local Air Quality in 3 Steps
1. View Your Real-Time Local AQI Score
Visit AirNow.gov or your smartphone’s default weather app. Enter your zip code to instantly find your current local AQI number.
2. Decode the Color-Coded Health Risks
- Green (0–50): Good air; perfectly safe for outdoor activities.
- Yellow (51–100): Moderate air; highly sensitive individuals should monitor symptoms.
- Orange (101–150): Unhealthy for sensitive groups; children, seniors, and asthmatics should limit outdoor time.
- Red (151–200): Unhealthy for everyone; everyone should reduce strenuous outdoor exertion.
- Purple/Maroon (201+): Very unhealthy to hazardous; avoid all outdoor physical activity.
3. Identify the Dominant Pollutant
Check if your local alert is driven by ground-level ozone (common on hot, sunny summer afternoons) or particulate matter ($\text{PM}_{2.5}$ and $\text{PM}_{10}$), which stems from wildfire smoke, dust storms, and vehicle exhaust.
