The Indian Institute of Technology, Delhi (IIT-Delhi) has devised technological solutions to combat air pollution in the country. With the establishment of Centre of Excellence for Research on Clean Air (CERCA) in February 2018, the institute has come up with devices to control polluted air.

The cost-effective devices, as per a release by IIT-Delhi, can provide temporary relief from air pollution in the national capital and other states of north India. One such device, the Chakr Shield, helps to convert pollutants to ink that can be used for drawings. The retrofit device by the IIT Delhi alumni can trap 90 per cent of particulate matter in the exhaust, thus reducing the pollution caused by the diesel generators.

Meanwhile, the Nasofilter, which was designed in 2017, can protect users from air pollutants, including PM 2.5 particles, and reduce the risk of respiratory diseases.

The start-ups by the alumni, students and teachers received the ‘Startup National Award’ 2017 by former President Pranab Mukherjee, and also made it to the South Korean government’s list of ‘Top 50 technical startups in the world’.

The device helped to keep away PM 10 particles by 100 per cent, and PM 2.5 particles by 95 per cent. The filters can last up to 8-10 hours.

Another start-up Kriya Labs developed a processing technology in an attempt to curb pollution due to crop burning. The technology was developed to convert agro-waste like rice straw into pulp, which can then be used to make several biodegradable products like cups, plates and other tableware.

The Ezio air pollution monitor is designed to check the level of pollution in our local environment, such as inside a room, car or outdoors. The device by the startup Aerogram Private Limited can also help create a detailed map for entire cities and figure out the levels of pollution in different areas.

Shudhvayu innovations is another startup which is working to remove PM10 in bulk by installing the design 5) registered air purification device on a multitude of vehicles.
