More than 80% of people in urban areas are exposed to air quality levels that exceed the World Health Organization limits. As Korea is also suffering from severe fine dust nowadays, “Smog Free Project” is welcomed as a local solution and inspiration for a smog free environment. Daan Roosegaarde and his team of experts have created the world’s largest smog vacuum cleaner. Smog Free Tower uses patented ion technology to produce smog free air in public spaces, allowing people to breathe and experience clean air for free. Smog Free Project provides a local solution for clean air in public spaces such as in parks. Creating a tangible souvenir, Roosegaarde designed Smog Free Rings of compressed smog particles. Sharing a Smog Free Ring is tantamount to donating 1,000㎥ of clean air to the city.
