The SMOG FREE TOWER is a 7-meter-tall aluminum structure that uses just 1170 watts of green electricity and positive ionization technology to clean the air. Validated by Professor Dr. Bert Blocken from the Eindhoven University of Technology, it has been successfully deployed in South Korea, China, the Netherlands, and Poland. Created by Daan Roosegaarde in collaboration with the engineers of Studio Roosegaarde, ENS, and advisor Ursem (until 2013), the SMOG FREE TOWER is a symbol of innovation in air purification.

Complementing the tower, the SMOG FREE RING designed by Studio Roosegaarde transforms smog particles into wearable jewelry, making pollution tangible in a unique way. The SMOG FREE RING is part of the permanent art collections of both the National Museum Zurich and the Stedelijk Museum Amsterdam.

The SMOG FREE BICYCLE draws its inspiration from the Smog Free workshop in Beijing, featuring artist Matt Hope and Professor Yang from Tsinghua University, further expanding the project’s reach into urban mobility and sustainable design.

Additionally, the SMOG EATING BILLBOARD by UDEM University in Mexico offers another innovative approach to air purification. With a special coating that uses photocatalysis powered by sunlight and wind, the billboard purifies air for 104,000 people each day, turning public space into a clean air generator. Together, these creations represent a new vision for cleaner cities and a healthier future.

Clients, including green companies or cities, can commission a SMOG FREE PROJECT campaign that encompasses a SMOG FREE TOWER, SMOG FREE RING, project management, and innovation workshops.
