What do AQI levels actually tell us? What are the short and long term effects of air pollution? Why doesn’t the WHO recommend masks for air pollution? Do air purifiers really help? And what steps can the government take to tackle this problem effectively?

Today on the show, we are joined by Dr. G.C. Khilani to discuss everything you need to know about air pollution. Dr. Khilani is the chairman of Pulmonary, Critical Care & Sleep Medicine at PSRI Hospital in Delhi and a member of the WHO's Technical Advisory Group on Air Pollution and Health.
