Discover how air pollution affects your health in cigarette equivalents
The Air Quality Index (AQI) is a standardized measure used worldwide to communicate how polluted the air currently is or how polluted it is forecast to become. AQI values range from 0 (good) to 500 (hazardous).
AQI is calculated based on pollutants like PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide.
Research shows that breathing polluted air can be as harmful as smoking cigarettes. This calculator helps you understand the health impact of air pollution in relatable terms.
PM2.5 particles in polluted air can penetrate deep into your lungs and bloodstream.
Long-term exposure increases risk of heart disease, stroke, and respiratory illnesses.
Children, elderly, and those with pre-existing conditions are most at risk.
When AQI is high, limit outdoor exposure
Use air purifiers and keep windows closed
Use certified masks (N95 or better) outdoors
Promote green spaces and reduce personal pollution
