Anumita Roychowdhury, an air quality expert, expressed concern, citing past failures. “The best example is our two Delhi smog towers at Anand Vihar and Connaught Place. As of now, we have not seen any evidence to suggest that outdoor air purifiers can clean the air over a meaningful distance,” she said.
However, many think that it is essential to reduce vehicular and industrial emissions; improving public transport and green policies are better ways to control air pollution. However, despite criticism, officials think that this new effort is expected to bring relief in polluted public spaces.
