Detailed explanation-2: -WAYU is developed by Council of Scientific and Industrial Research – National Environmental Engineering Research Institute (CSIR-NEERI) as a part of Technology Development Project being funded by Department of Science and Technology.

Detailed explanation-3: -Working: The device works on two principles mainly wind generation for dilution of air pollutants and active pollutants removal. It has filters for particulate matter (PM) removal and activated carbon (charcoal) and UV lamps for poisonous gases removal such as Volatile organic compounds (VOCs) and Carbon Monoxide.

Detailed explanation-4: -The full form of WAYU is Wind Augmentation PurifYing Unit. The device was installed for traffic junctions at ITO intersection and Mukarba Chowk in New Delhi.
