Delhi could breathe easier this year as a post-Diwali toxic haze cleared up much faster than it did in 2015 and 2016 because of favourable weather conditions and pre-emptive steps to reduce air pollution, experts said. This year, the Delhi air improved to “poor” in three days after Diwali, going from 403 on Friday to 300 on Monday. A key factor that has worked for Delhi is a favourable wind that blew away the filth in the air. “The air quality in October hardly remains in ‘moderate’ or ‘satisfactory’ zones. This means, if we have returned to the ‘poor’ zone we are breathing somewhat clean air,” said a Delhi Pollution Control Committee official.
