Air pollution is a serious concern with the developing economics in India and gets more severe when it has major cities ranked among top 30 polluted worldwide. To find solution, different programs and/or policies have been launched for air quality management country-wide. Unfortunately, no such plan could effectively solve purpose rather than an unexpected COVID-19 pandemic situation India. Our study focused on status index (AQI) 42 (that includes 6 metros) representing North, South, East, West, Central, North-East region of during pre-lockdown, four lockdowns unlock phases. The results depict most pollutants except ozone (O3) were significantly reduced lockdown-1, marginally increased subsequent lockdown Regarding average AQI, its value was highest North Indian (227), followed by East (172), Central (141), (130), West (124), South (83) pre-lockdown. Due to induced lockdown, observed dip AQI (108), (113), (82), (73), (55), (49) Thus, gave conspicuous vision mitigation under this pandemic; and, if strategic centralized are sensibly implemented involving participation people India, then there feasibility issue management.
