Air purifiers at traffic intersections: Experts call it mere band-aid fix

In a rather desperate move to counter the severe air pollution in Delhi, the government wants to install air purifiers at traffic intersections. But experts feel the idea is flawed on various counts. While this is more of a band-aid solution that doesn’t bring down vehicular emissions, the system may also not be as effective in “purifying” polluted air. Each device, it is claimed, helps purify the air of up to 40% pollutants, including particulate matter, carbon monoxide and hydrocarbons, [...]

Clearing the air:How effective are the purifiers?

Air purifiers are devices that aim to clean indoor air by filtering out particulate matter like dust and pollen, gaseous pollutants like hydrocarbons, and unpleasant odours. According to manufacturers, in most devices, air passes through three layers of filters — a “pre-filter” that captures the bigger particulates, a carbon-activated middle filter for gaseous pollutants, and the innermost “High Efficiency Particulate Arrestance”, or HEPA, filter whose intricate honeycomb structure captures finer particulates. Manufacturers usually promise additional benefits through the use of other [...]
