Air Quality Today

Air quality changes throughout the day based on weather patterns, traffic, industrial activity, and seasonal factors. The Air Quality Index (AQI) is the standard measurement used worldwide to communicate how polluted the air is. An AQI below 50 is considered good, while anything above 100 may be unhealthy for sensitive groups.

PM2.5 (fine particulate matter) is the most harmful air pollutant, penetrating deep into the lungs and bloodstream. The WHO recommends annual PM2.5 levels below 15 µg/m³. Check your city above to see current PM2.5 levels and health recommendations.
