An IIT Kharagpur graduate Debayan Saha has developed a device that will prove to be effective in curbing vehicular air pollution. The device called “PM 2.5” which he claims when fitted near the silencer pipe in vehicles could curtail pollution to substantial level.

One car fitted with the device can neutralise the pollution emitted from 10 cars in its vicinity, Saha, a mechanical engineering graduate claims.

“The technology developed by us uses a combination of electric energy and wave energy to influence the pollutants like PM 2.5 such that they act like a magnet attracting other particulate pollutants from the ambient atmosphere to get attached to it. As they grow bigger in size they become heavy and fall off safely on the ground like soil,” said Saha, who was also a research fellow at AIIMS who worked on air pollution.

“One car on the street can now alleviate the pollution in its immediate environment, and potentially neutralize the pollution emitted from 10 cars in its vicinity. Diving really deep into the problem they found main culprit is not PM- 2.5 but its tiny size because of which it can easily enter into our lungs and bloodstream,” he said.

Saha, is in talks with various organisations, to commercialise the product.

A blanket of toxic haze shrouded the national capital region on Wednesday, as air quality in Delhi and the adjoining areas plunged to “very poor” levels, affecting visibility and causing inconvenience to residents.

The Delhi government attributed the dip in the air quality to rampant stubble burning in neighbouring states, a regular feature in October-November.
