This week on #PollutionKaSolution#, we look at four innovations that could potentially work in Delhi’s pollution hotspots, from giant air-filtering cubes to technology that claims to reduce our exposure to pollution, devices that can turn a car into a moving air purifier, and systems that combine air filtration with renewable energy. How practical are these solutions? Watch in. #PollutionKaSolution# #DelhiPollution# #AirPollution# #Pollution# | @suyeshasavant
