Once a luxury product, air purifiers have increasingly become a necessity as sales surge amid a rise in Delhi's pollution levels that are now just a notch below the 'Severe Plus' category.
According to Central Pollution Control Board data, Delhi's overall Air Quality Index (AQI) stood at 426 at 9.30 am on Friday. An AQI of above 400 is considered 'Severe' and can affect healthy people and seriously impact those with existing illnesses. On Thursday, the 24-hour average AQI stood at 450 at 4 pm, just a notch below the 'Severe Plus' category.
Demand for air purifiers have risen in the national capital, particularly after Diwali, which witnessed widespread bursting of firecrackers despite a ban.
"The air quality in India is deteriorating due to many activities industrial expansion in cities, population density, improper waste management, crop burning, increased automobile use and a few natural causes. There is evidence that air pollution, both outdoor and indoor, is on the rise and is behind higher morbidity and mortality rates," said Kartik Singhal, founder of O2 Cure and managing director at Zeco Aircon Ltd.
