Chinese authorities are all geared up for yet another scientific advancement in the face of excessive smog that has hit the capital city of Beijing.
The authorities have decided to deploy an air purifier – the world's largest – as thick heavily polluted haze has returned to scare the city.
The seven-meter-tall tower, the brainchild of Dutch designer Daan Roosegaarde, is undergoing last-minute checks in Beijing's 751 D Park art area.
The 'Smog Free Tower' will soon be opened to the public, and will be toured across the country, state-run Global Times said, quoting China Forum of Environmental Journalists, an NGO under China's Ministry of Environmental Protection.
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 meters of air per hour through its patented ozone-free ion technology.
Beijing has been plagued with heavy smog since the beginning of October. The city's environmental authorities issued a "yellow alert" for air pollution on Tuesday.
