Startups show ways to fight air pollution

35-year old Jay Kannaiyan founder of Delhi-based Smart Air, habitually does his morning walks and exercises late afternoons between 3-5pm and not during the most commonly prescribed early morning hours.

According to Central Pollution Control Board, during early morning hours when humidity level is high, PM levels are above 500 while during the day time, they usually hover around 250-300. The safe limit of PM 10 is 100µg/m³ and PM 2.5 is 60µg/m³, which shows that Delhi on Monday witnessed nearly 8x of the most hazardous components of air pollution.

He reasons that this daily habit helps him to avoid the worst affected hour in the capital when the pollution is at its peak, after the movement of heavy vehicles at night.

Jay advises the same to his colleagues at Smart Air which manufactures air-purifiers. SmartAir believes in lowering the costs of air purifiers, thus making it affordable for everyone.

Starting from Rs 3,000 these air purifiers, work on high-efficiency particulate arrestance (Hepa) technology. It is attached to the table fan and through that it filters the air and collects the particulate matter (PM)- which is fine particulate matter about 25 times finer than a human hair and the most hazardous pollutant- reducing the pollutants by 90%.

For past few years, air pollution has been a severe global concern particularly in India where countable measures have been taken to curtail the rise. Of the world’s top 20 polluted cities, 13 are in India compared to just three in China. Since 2000, though Beijing’s air pollution has dipped by 40%, in India Delhi’s air pollution has steadily climbed by 20% in the same period.

According to Central Pollution Control Board, during early morning hours when humidity level is high, PM levels are above 500 while during the day time, they usually hover around 250-300. The safe limit of PM 10 is 100µg/m³ and PM 2.5 is 60µg/m³, which shows that Delhi on Monday witnessed nearly 8x of the most hazardous components of air pollution.
