It means exactly as it sounds like. Polluted air is forced in from the top and clean air comes out from the bottom. The tower is more than 20 metres high. This helps reducing particular matter in a localised environment.

The tower was built by Tata Projects Limited in collaboration with NBCC (India) Ltd as their consultant. The filtration system was developed by the University of Minnesota.

No, a week ago another smog tower was inaugurated at Connaught Place but that tower is not functional yet and filters are still being installed.
