Smog Free Tower Cleans Air In Beijing
Beijing-based Dutch designer Daan Roosegaarde has designed the world’s largest air purifier and temporarily located it in the Chinese capital. The tower was switched on during the Beijing International Design Week last September.

The air in Chinese cities is amongst the most polluted in the world. Smog in Beijing contains over five times the acceptable maximum amount of dust particles according the World Health Organisation. With nearly 1 million dust particles per cubic metre, public health is severely compromised, with the old and the young particularly at risk. The situation is so dire that the capital has been prioritised for measures against smog. Air pollution causes over a million deaths per year throughout China.
The project began in 2013, after a successful pilot in Rotterdam the project has now started a tour across the globe. The Smog Free Tower contains patented ozone-free ion technology and uses a small amount of green electricity. The Smog Free Tower captures and collects more than 75% of the PM2.5 and PM10 airborne smog particles and releases clean air around the tower with a 360-degree coverage creating an almost circular zone of clean air in its surrounding, area. It literally creates a bubble of clean air over the city.
The seven-meter high air purifier is located in a former industrial area, which has been transformed into a creative hub for designers. When open it is shaped a bit like a pagoda. The electromagnetic vacuum cleaner dubbed Smog-Free Tower uses subterranean copper coils to suck up airborne particles by generating an electrostatic field. It purifies 30,000 cubic metres of air per hour. As the smog lifts residents of Beijing will enjoy cleaner air and better views.
