A purifier of air for building sites

Students of the Utec of Lima (University of Engineering and Technology) invent a device to clean up the city and the construction sites. A purifier of air integrated into an advertising hoarding which inhales the polluting particles of the ambient air thanks to an integrated(joined) water tank. The results of the prototype: 99 % of got pollutants, 100 000 m3 of the air cleansed a day, is the equivalent of 1 200 trees.
