“AQI 135 in the morning — the app suggests waiting until 4 PM. It offers me a 7.3 km route through AQI 76 zones instead of the usual 5.2 km with AQI 142. Result: 30% less PM2.5 exposure.”
Five-year outlook: 5M+ people protected, 15–20% fewer hospital admissions, $100M+ in healthcare savings, 2.3 tons of PM2.5 avoided.
