The AQI Cigarette Calculator is a simple but powerful concept. It compares the health impact of breathing polluted air with smoking cigarettes. For example, spending a day in very polluted air may feel normal, but when the calculator shows it is equal to smoking several cigarettes, people instantly understand the risk. This tool has helped many people realize that air pollution is not a distant or invisible threat. It directly affects the body, lungs, heart, and overall health.
