After debuting in the Dutch cities of Rotterdam and Amsterdam last year, Studio Roosegaarde's Smog Free Tower has taken on its biggest challenge yet. It opened in Beijing, China, at the end of September and, in 41 days, cleaned 30,000,000 cu m (1,060,000,000 cu ft) of air.

Studio Roosegaarde says that equates to about 10x the volume of Beijing's Bird's Nest stadium. From that, it is said to have captured billions of the finest harmful airborne particles (those 2.5 micrometers (µM) or less) during that time, and over 75 percent of particles between 2.5 µM or less and 10 µM in size in the vicinity of the tower.

The tower requires 1,700 W to operate and uses a current to send positively-charged ions out into the surrounding air that attach themselves to particulate matter. These particles are then attracted back into the tower and captured by an internal negatively-charged surface. It is able to clean the surrounding air in 360 degrees, effectively creating a bubble of clean air.

The smog particles that are collected are compressed into small cubes and used to create jewelry. Each cube contains 1,000 cu m (35,300 cu ft) of particles and is set into a ring that can be worn as a souvenir of clean air. In Beijing, 300 limited edition rings have been made using the particles collected.

Studio Roosegaarde suggests that the Smog Free Tower could serve as a means of cleaning air in localized areas such as parks and public spaces. It is said to have attracted many visitors during its time in Beijing and will now be toured around a number of other Chinese cities.

These devices might help in the short term, but I think China would be better served by enacting pollution control policies and laws. I lived in Los Angeles in the early 1960's, when I was a kid, and remember smog alerts in the middle of summer vacation. You had to go and stay indoors in the middle of the day, because the smog was so bad it hurt to breathe. California instituted some of the strictest pollution laws in the world and it's made a huge difference.

It's a start. Now add Solar panels and a wind turbine so it doesn't need to pull that 1,700W from the grid.

That's remarkably little energy and easily supplied by solar panels - well done!

I would be interested to know how much particulate has actually been removed in weight. Billions of particles does not mean much. 1000 cubic meters of particles was compressed into a ring. don't think so , more like the particles from 1000 cubic meters of was compressed into enough material to make a ring. If that is the case I am not impressed , in a month a small box worth or dirt was removed from the air. A PR exercise , not much else

Need this for Mex City 2, & other cities IE Inland Empire, LA CA. Mass produce.

It's a touching gesture to bring more awareness to this presssing problem, but the cost effectiveness of this device is in doubt: http://qz.com/846093/chinas-giant-smog-sucking-tower-was-simply-no-match-for-its-air-pollution/ By far, it would be more effective (and very costly) to deal with the root problem.

With these China will have the best air on Earth...they just need roughly a million more.

Here's an idea. Any industry creating pollution should be required to mitigate through whatever means an equal or even more pollution than they create. Not just new polluters but every old and new polluter. Pretty soon we'd figure out that creating air and water pollution is a no go.
