New Delhi and the areas surrounding the city have been engulfed by a cloud of smog which is choking the city and its residents. The air quality index has reached hazardous levels as the Indian capital has been hit by the worst pollution in three years. A public health emergency has been declared and people have been advised to stay indoors.

According to a report in Khaleej Times, as smog levels exceeded, authorities parked a van with an air purifier near the Taj Mahal – the iconic 17th-century marble mausoleum 250 kilometres (150 miles) south of Delhi – in a bid to clean the air in its surrounds.

The air purifier van deployed by the Uttar Pradesh Pollution Control Board (UPPCB) has the capacity to purify 15 lakh cubic metre air in eight hours within a 300-metre radius.
