Wind purification units installed at traffic junctions across Mumbai

With traffic conditions worsening in the city, officials said that the level of carbon monoxide was at its highest during peak hour traffic.

To tackle the toxicity in Mumbai’s air, wind purification units have been set up at three traffic junctions and are likely to be operational by next week, officials said. These units, called WAYU (Wind Augmentation and Air Purifying Unit), will be used to suck in the particulate matter and release fresh air.

According to officials, five unit were set up last week across three signals. While, three units were set up at Sion Circle and one unit each was installed at junctions in Ghatkopar and Bhandup. Three more units at Kalanagar junction are expected to be installed.

“These unit have been installed at dividers and requires electricity. We needed to ensure that they do not obstruct traffic. They will be operational next week and we are expected to have more installed across the city,” said a senior official from the Maharashtra Pollution Control Board.

With traffic conditions worsening in the city, officials said that the level of carbon monoxide was at its highest during peak hour traffic.

“We have selected these junctions as they are places with very high particulate matter. WAYU is an active air pollution mitigation technology that works on the principle of breaking down carbon monoxide,” the official added. The gadget WAYU was created in a joint collaboration between National Environment Engineering Research Institute (NEERI) and Indian Institute of Technology (Bombay).

The lead pollutant in the air is particulate matter (PM) 2.5 – are small pollutant particles that could enter the lungs and PM 10 – slightly larger, coarser particles, both were expected twice more than their safe limits.

Currently Mumbai’s air quality levels, including the particulate matter are ‘poor’, according to SAFAR. The Air Quality Index (AQI) is recorded by System of Air Quality and Weather Forecasting and Research (SAFAR), which is run by the Indian Institute of Tropical Meteorology with the support of India Meteorological Department.


On Thursday evening Mumbai’s AQI was 294, marginally improving from Wednesday’s reading of 309. Officials said that with low temperatures and low wind speed, the AQI level are expected to be ‘poor’ for another week.
