The 24-metre-high smog tower at Connaught Place, one of the biggest commercial centres in the capital, is based on a downdraft air-flow model.
A smog tower is a structure designed to work as a large-scale air purifier, fitted with multiple layers of filters which trap fine dust particles suspended in the air as it passes through them.
Air is drawn through fans installed at the top of the tower, passed through filters, and then released near the ground.
In November 2019, an expert panel estimated that Delhi will need a total of 213 anti-smog towers to battle the pollution crisis. On 3 January, Delhi’s first smog tower came up at the Lajpat Nagar Central Market.
