The Delhi government has asked agencies to intensify the use of anti-smog guns at construction sites and key stretches to control dust emissions. (Image: News18), Anti-smog guns spew fine, atomised water droplets through high-pressure propellers in the air, making a canopy effects. (Image: News18), The device uses high-pressure water fogging with turbo air flow, which creates an ultra-fine fog consisting of very fine water droplets.

(Image: News18), These water droplets suppress the particulate matter — PM10 and PM2.5, which are the most prominent pollutants in Delhi’s air — and help cleanse the air.
