Dutch innovator brings a breath of fresh air to Beijing

The residents of Beijing can literally heave a sigh of relief. From now on the air they breathe will be cleaner.  To mark the Beijing International Design Week, the city authorities have switched on  the world’s largest air purifier. The contraption was built by Beijing-based Dutch designer Daan Roosegaarde.

Chinese cities have some of the worst smog in the world. Beijing’s air contains over five  times  the acceptable maximum amount of dust particles according the World Health Organisation.  With 120 dust particles per cubic metre, it is a major health issue in the Chinese capital. Although its denizens are lucky as the capital has been prioritized for improving the air quality. Every year, there are more than a million deaths in China related to air pollution.

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.

Air purifier

Daan Roosegaarde and his team have been developing the project at Studio Roosegaarde since 2013, after its successful pilot in Rotterdam the project has now started a tour across the globe.

The seven-meter high air purifier is located in a former industrial area, which has been transformed into a creative hub for designers. 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, which means Beijing’s residents will not only get to know the taste of fresh air, they will be able to see much better too as the smog lifts.
