On August 23, Arvind Kejriwal, Chief Minister of Delhi inaugurated the "country's first smog tower" at Connaught Place in Delhi. The tower will purify air in a 1-km radius at a rate of around 1,000 cubic metres of air per second. Kejriwal said that many such structures can be installed in the national capital if this pilot project yields results. "This is the first such smog tower in the country. It's a new technology,” he said. The smog tower has 40 fans & around 5,000 filters developed by experts at the University of Minnesota. A Delhi government statement said the 24-metre-high smog tower is based on a downdraft air-flow model. The statement added that the tower’s 40 huge fans will suck air from the top of a special type of canopy structure and release clean air filtered through novel geometry filters.
