Dutch designer Daan Roosegarde created the Smog Free Tower with Bob Ursem of Delft Technology University, and Dutch green tech company European Nano Solutions.

The seven-meter tall structure can be currently found in Beijing's sprawling 751 D.Park industrial complex, one of the main hubs for Beijing Design Week. After Beijing Design Week, Roosegaarde will tour it around China.

The Smog Free Tower cleans 30,000 cubic meters of air per hour via patented ozone-free ion technology and uses a small amount of green electricity.

A hybrid between a spaceship and a traditional Chinese pagoda, the structure is charged with a small positive current and uses ion technology to suck pollution into its chambers and purify it.

"The Smog Free Tower is about the dream of clean air for everyone," says Roosegarde. "The goal for now is to be able to make permanent versions of the towers and integrate them into the urban landscape. Eventually though, I'd like them to become relics of our time."

Catch of the day: A sample of Beijing's dust particles on a semi-low air quality index day.

Striving to follow a zero-waste approach to his smog-free vision, Roosegaarde and his team compress the smog particles collected from the Smog Free Tower to turn them into jewelry.
