This shimmering park tower isn't just a glamorous piece of architecture: it is the largest air purifier in the world, and it is turning China's smog into diamonds.

The tower is a 23-foot tall metal structure that is capable of filtering 75% of harmful PM2.5 and PM10 particles from the surrounding air, thus producing 30,000 cubic meters of clean air per hour. This creates a bubble of air around the tower, offering smog-free solace to urban dwellers. (More here)
