For Delhi, reeling under a suffocating smog, a solution from China
Daan Roosegaarde and his team of experts have created the world’s largest smog vacuum cleaner. The 7-meter (23 feet) tall SMOG FREE TOWER uses patented positive ionisation technology to produce smog free air in public spaces, allowing people to breathe and experience clean air for free. It is equipped with environment-friendly technology, cleans 30.000 m3 per hour and uses no more electricity than a water boiler (1170 watts). The SMOG FREE TOWER provides a local solution for clean air such as in parks. The effect of the Smog Free Tower has been validated by the results compiled by the Eindhoven University of Technology.
