The Smog Free Tower is a part of the Smog Free Project which was started in 2013 by Studio Roosegaarde, the design lab created by award-winning Dutch innovator Daan Roosegaarde. He said that this project aims to become an awareness of today's pollution problem and an inspiration for everyone to be a part of the solution.
The Tower, which stands 7 meters high, is the largest air purifier in the world. It works through a patented ozone-free ion technology and uses only a small amount of green technology. It captures more than 75 percent of the PM2.5 and PM10 smog particles at a rate of 30 cubic meters of air per hour.
The Tower then creates a bubble of clean air and releases this in a 360-degree scope, generating a circular zone of clean air around it.
The impact of this project to the environment can be held in a perceptible evidence in the Smog Free Jewellery, which consists of the Smog Free Ring and Smog Free Cufflinks.
The smog particles collected from the Tower are compressed into small cubes and are used to decorate pieces of jewelry. Each Smog Free Cube is equivalent to 1000 cubic meters of clean air.
Roosegaarde's many visits to China, particularly during a stay in Beijing when he could not see outside his hotel and children were kept from going outdoors because of too much smog, sparked the idea. He said, "Smog Free Project is about the dream of clean air and the beginning of a journey toward smarter cities."
The innovator added that he is delighted to bring his project to the "bustling creative community" in Beijing and that he looks forward to collaborating for more ideas and solutions.
The Smog Free Project is supported by the Chinese Ministry of Environmental Protection and the China Forum of Environmental Journalists. The latter's Secretary-General Liu Guozheng said that this project is ''key in their agenda to promote clean air as a 'green lifestyle' among Chinese citizens."
