Smog tower


Smog towers are structures designed as large-scale air purifiers to reduce air pollution particles, the prototype for which was built in 2017 by Dutch artist Daan Roosegaarde, in Beijing.

Examples

Roosegaarde's 2017 prototype was later installed in Tianjin and Krakow. In 2018, a tower has been built in Xi'an, Shaanxi to tackle the city's pollution. It is under testing by researchers at the Institute of Earth Environment of the Chinese Academy of Sciences.
In Delhi, Kurin Systems is developing a tall smog tower, called the "Kurin City Cleaner". It is claimed the tower will filter air for up to 75,000 people within a radius. The Kurin City cleaner would be the strongest air purification tower, cleaning more than 32 million cubic meter of air every day.
