Designer Daan Roosegaarde has built the largest ever air purifier, which is the result of three years of research and development.
The final product is a tower that scrubs the pollution from more than 30,000 cubic meters of air per hour—and then condenses those fine particles of smog into tiny “gem stones.”
The stones are then manufactured and can be embedded into pieces of jewelry, including rings and cufflinks.
The project, which was funded on Kickstarter, took about three years of research and development, but Roosegaarde was finally able to show off his massive machine in September in Rotterdam.
Now, Roosegaarde and his team have partnered with the Chinese Ministry of Environmental Protection to take the giant air purifier on a tour of China to help clean up the air.

The fine carbon particles that the tower collects can be condensed to create tiny “gem stones” that can be embedded in jewelry pieces like rings and cufflinks. Each of the tiny stones is the equivalent of 1,000 cubic meters of air.
“The Smog Free Tower produces smog-free bubbles of public space, allowing people to breathe and experience clean air for free,” said a statement from Roosegaarde.
The smog is sucked in through its top, then the purified air is released through vents on the six sides. Its patented technology works in a similar way to air purification systems used in hospitals.
