Air Quality Index (AQI) Scale

0-50 Good - Air quality is satisfactory
51-100 Moderate - Acceptable; sensitive groups may experience issues
101-150 Unhealthy for Sensitive Groups - Children, elderly, and those with respiratory conditions should limit outdoor activity
151-200 Unhealthy - Everyone may experience health effects
201-300 Very Unhealthy - Health alert; everyone should reduce outdoor activity
300+ Hazardous - Emergency conditions; avoid all outdoor activity

Key Pollutants

PM2.5 - Fine particles (<2.5 micrometers) that penetrate deep into lungs
PM10 - Coarse particles (<10 micrometers) from dust, pollen
Ozone (O3) - Ground-level ozone from vehicle/industrial emissions
NO2 - Nitrogen dioxide from combustion engines
CO - Carbon monoxide from incomplete combustion

Frequently Asked Questions

What AQI level is safe?

AQI 0-50 (Green/Good) is safe for everyone. Sensitive groups should be cautious above 100.

How does wildfire smoke affect air quality?

Wildfire smoke dramatically increases PM2.5 levels. Smoke can travel hundreds of miles, affecting air quality far from fires.

Why is air quality worse in the evening?

Temperature inversions trap pollutants near ground level, often occurring in evening/overnight hours. Traffic emissions also peak during commute times.
