Talk about a game-changer. A billboard that purifies air in construction zones? It's real and it's in Peru. There's a construction boom taking place in Peru but with that comes polluted air that nearby residents and construction workers are exposed to. The University of Engineering and Technology in Peru (UTEC) is building a campus, so technically it's part of this pollution problem. It also is part of the solution. UTEC teamed up with FCB Mayo to create a billboard that removes dust, metal and stone particles from the air, purifying it more than 1,200 trees could. The billboard was erected in the middle of the construction site, absorbing the polluted air and filtering it through a water system that emits clean air that's fit to breathe. The billboard can produce 100,000 cubic meters of clean air a day. The clean air reaches a five-block radius. See it here.
