Sales of air purifiers have surged in northern India and other regions as pollution levels continue to rise. The demand for air purifiers has reached record levels, with brands such as Xiaomi, Philips, Havells, and Kent experiencing strong sales. Premium makers like Dyson and Daikin are also receiving aggressive orders. The increase in demand is not limited to the Delhi-NCR region but has extended to Mumbai and other parts of the country. Companies anticipate further growth in demand as air quality continues to deteriorate and awareness about air purifiers increases.
