Dutch designer Daan Roosegaarde and his team of experts have created the world's largest smog vacuum cleaner. The Smog Free Tower uses patented positive ionization technology to produce smog-free air in public space, allowing people to breathe and experience clean air for free. The Smog Free Tower cleans 30.000 m3 per hour, and uses no more electricity than a waterboiler (1170 watts).

Creating a tangible souvenir, Roosegaarde designed Smog Free Rings and Smog Free Cufflinks made of compressed smog particles. By sharing Smog Free Jewellery, you donate 1000 m3 of clean air to the city. The Smog Free Project is not only intended to be a local solution for parks, but also an inspirational experience of a clean future.

Along with governments, NGOs, pro-bicycle campaigns and the clean-tech industry, people can work together to make a whole city smog free. The Smog Free Project is currently on tour in China with the support of China's Ministry of Environmental Protection and the Embassy of the Kingdom of the Netherlands.

The Smog Free Project is an experience of a clean future and serves as an inspiration for citizens, governments, NGOs, pro-bicycle campaigns and the clean-tech industry to become part of the solution, working together to make cities smog free. The Smog Free Project, created by Dutch artist and innovator Daan Roosegaarde and his team of designers and experts, consists of the Smog Free Tower and Smog Free Jewellery offering a unique sensual experience of a clean future. Daan Roosegaarde and his team have been developing the project at Studio Roosegaarde since 2013, after its successful pilot in Rotterdam the project is now starting a tour across the globe.

The 7 meters high Smog Free Tower is the largest air purifier in the world which creates a bubble of clean air enabling citizens to experience clean air for free. The Smog Free Tower cleans 30.000 m3 per hour via patented ozone-free ion technology and uses a small amount of green electricity. The Smog Free Tower captures and removes up to 70% of the ingested PM10 and up to 50% of the ingested PM2.5. It releases clean air around the tower with a 360-degree coverage creating an almost circular zone of clean air in its surrounding.

The Smog Free Jewellery is a tangible souvenir of the Smog free Project. The Smog Free Ring and Smog Free Cufflinks are made from compressed smog particles collected from the Smog Free Tower. By sharing a Smog Free Ring, you donate 1000 m3 of clean air.

The Smog Free Project is inspired by Roosegaarde's numerous travels in China and particularly by a visit to Beijing in 2013 when he could not look up out of his hotel room and children were kept indoors due to the severity of the smog. More than 80% of people in urban areas are exposed to air quality levels that exceed World Health Organization limits. The Smog Free Project is a part of Roosegaarde's larger oeuvre 'Landscapes of the Future' which connects people, technology and space to improve the quality of daily life in urban environments.
