CSIR’s innovation to tackle Delhi pollution

Delhi is known to have an air pollution problem. People there are suffering constantly due to the polluted air which can cause many health problems.

The government has tried several solutions to help curb the air pollution but not much has changed.

Now, a new kind of technology has been made by The National Environmental Engineering Research Institute (NEERI) which comes under the Council of Scientific and Industrial Research (CSIR).

They have made a device which can curb the air pollution in areas with a lot of traffic.


The device consists of a fan which sucks air around it. From this air, the pollutants are separated using three different filters.

The air then passes into a chamber where harmful contents like carbon monoxide and hydrocarbons are converted into something less harmful like carbon dioxide.

After that, the purified air is sent back into the atmosphere which reduces the pollution content in the air.

The device is named WAYU. So far, it has been installed at the ITO Junction in central Delhi and Mukarba Chowk in north Delhi.

It has been planned to install 54 more of these devices in various parts of the city to curb pollution over the next month. Each of these devices costs only ₹60,000.

According to Dr. Rakesh Kumar, the director of NEERI, the filters of the device are made with non-woven fabric.

They have an efficiency of 80 – 90 percent for removing particulate matter and 40 to 50 percent of efficiency to remove  harmful gases.

Sitting at a height of 5.5 feet and a width of one foot, this device can reduce PM 10 values from 600 micrograms per cubic metre to 100 micrograms per cubic meter and PM 2.5 values from 300 micrograms per cubic metre to 60 micrograms per cubic metre in just half an hour.

The device is also quite efficient with electricity and consumes only one unit of electricity per 10 hours.
