Smog Free Tower, the 7-meter-tall air purifier designed by Dutch artist Daan Roosegaarde, has begun tests in Beijing. The innovative creation will eventually be exhibited around China to promote smog reduction.

The tower is capable of purifying 30,000 cubic meters of air per hour, and the smog particles it collects are compressed to make diamonds. Using ion technology and green energy, the tower captures at least 75 percent of PM2.5 and PM10 air pollution particles. In this way, it creates a large bubble of clean air around the tower.

The particles it collects are compressed to make diamonds.

Liu Guozheng, secretary general of the China Forum of Environmental Journalists, introduced the “smog reduction” activity as an educational event, which aims to encourage citizens to do their part in reducing pollution. But Liu also pointed out that the Smog Free Tower cannot be relied on to do all the work. The key to smog reduction still lies in pollution management, such as structural emissions reductions, adjustment of industrial structures and motor vehicle exhaust control.

Nevertheless, the Smog Free Tower can now offer instant smog alleviation in public places as a makeshift tool.
