Political parties and organisations here are distributing masks among people in view of deteriorating air quality in the national capital even as doctors express doubts over their efficacy.
Delhi BJP president Manoj Tiwari along with Abhiyan Delhi, an NGO, distributed masks at Connaught Place.
He asked Delhiites to be cautious and use masks while going out, especially in the early hours, a Delhi BJP statement said.
SAD-BJP MLA Manjinder Singh Sirsa, too, had distributed masks yesterday at the Connaught Place. He was accompanied by Delhi BJP leader Arvinder Singh Lovely and AAP MLA Kapil Mishra.
Following the the high level of air pollution, masks of various designs and patterns are selling like hot cake across the city. Low-priced masks include those for one-time use, while the costlier versions are fitted with air filters.
A senior doctor at a private hospital said that though surgical masks are the most common ones available in the market, they are not that effective, and suggested that one should opt for masks with two valves or vents.
There is not enough data on the efficacy of masks, AIIMS Director Dr Randeep Guleria had said recently.
"There is not much evidence about their efficacy," he had said, adding the use of nasal filters or air purifiers can provide short-term relief only.
