China to deploy world’s largest outdoor air purifier
China will deploy the world’s largest outdoor air purifier, seven-metre-tall tower, designed by a Dutch engineer in its smog-hit capital Beijing.

Functionality of Tower
The tower can capture about 75 per cent of PM 2.5 and PM 10 tiny particles in its vicinity and then release purified air to create a “bubble” of fresh air around it. The tower can clean 30,000 cubic metres of air per hour through its patented ozone-free ion technology.
