Smart mist sprayers at Kolkata's bus stands and roads — turning scorching streets into cool, breathable spaces.
"Cool the city.
Clear the air.
One mist at a time."
We believe public comfort is a right, not a luxury. Heat Mist is built for the people who wait — on streets, at bus stops, in the city's heat.
Kolkata summers are brutal. But rising temperature isn't the only threat — particulate matter and dust make every breath a burden. Mist tackles both.
Fine water droplets evaporate rapidly, absorbing ambient heat and lowering the surrounding air temperature by 6–10°C in under 2 minutes. Tested in tropical conditions similar to Kolkata's climate.
Mist particles bind to PM2.5 and PM10 pollutants, pulling them to ground level — up to 60% reduction in dust near sprayer zones.
Bus stand commuters bear the worst of Kolkata's heat. Our first installations target high-footfall stops, where even a few minutes of relief matters most.
Ultra-fine nozzles use a fraction of water compared to traditional sprinklers — optimised for maximum cooling per litre.
Our systems run on low-power motors and can be paired with solar. Misting doesn't burn fuel — it reverses the effect of those that do.
Whether you've felt our mist or simply believe Kolkata needs it — we want to hear from you. Your feedback shapes where we expand next.
