Air-purifying Billboard - Como 1200 Arboles
Designer: University of Engineering and Technology of Peru (UTEC) and FCB MAYO Peru (Humberto Polar)
A hoarding to transform pollution into clean air
This ordinary-looking billboard can in fact attract and filter pollution from the sky, returning purified air to the surrounding area at a rate of 100,000 cubic metres per day – equivalent to the work of 1,200 mature trees. It can also remove dust, metal and stone particles from contaminated air-space around construction zones.
