The most dangerous air pollution is often the one you cannot see. PM2.5 is among the most harmful air pollutants. It consists of microscopic particles that can travel deep into the lungs and enter the bloodstream. Exposure to PM2.5 has been linked to lung cancer, heart disease, stroke, asthma, and premature death, with children, older adults, pregnant women, and people with existing health conditions facing the greatest risk. We provide live PM2.5 measurements to help you stay informed and reduce your exposure when pollution levels become unsafe.
