Air Quality Index (AQI) Tracker
Get real-time air quality data for your location or any city worldwide. Monitor pollution levels, track changes, and protect your health with up-to-date AQI information.
Health Impacts of Air Pollution
- PM2.5 can penetrate deep into lungs and enter the bloodstream, increasing risks of heart and lung diseases.
- Ozone (O3) can trigger asthma attacks and reduce lung function, especially in children and outdoor workers.
- Long-term exposure to air pollution has been linked to premature death, lung cancer, and developmental issues in children.
Protecting Yourself from Air Pollution
When Air Quality is Poor:
- • Limit outdoor activities and exercise
- • Keep windows and doors closed
- • Use air purifiers with HEPA filters
- • Wear N95 masks when going outside
Understanding AQI Levels:
- • 0-50 (Good): Air quality is satisfactory
- • 51-100 (Moderate): Acceptable, but sensitive groups may be affected
- • 101-150 (Unhealthy for Sensitive Groups): General public not likely affected
- • 151+ (Unhealthy): Everyone may begin to experience health effects
