Smog-sucking tower: the world’s largest air purifier comes to life in China


Air pollution is a major concern all around the world today, with leading metropolises blanketed with thick smog most of the year. Of particular note is Beijing, which last year exceeded its national health standard by 1.3 times.

That thick Beijing smog has inspired a designer to take action to the next level. Dutch artist Daan Roosegaarde has created the world’s biggest air purifier, and he’s taking it on a tour of China, starting with Beijing.

He has created a 23-foot (7 m) tower that takes in dirty air and releases air with the tiny dust particles removed. Oh, and by the way, it takes that dust and turns it into jewels. The whole process is part of Roosegaarde’s Smog Free Project.

The tower, dubbed the Smog Free Tower, consists of 45 silver plates housing a huge internal air purifier. That purifier works by releasing positive ions into the air, which latch on to dust particles, particularly PM2.5 and PM10. Negative ions then attract the positive ions back into purifier, bringing the particulates along with them. It then traps the dust, and releases the air back outside, now 75% cleaner.
