The Smog Free Tower could help clean the air in cities around the world

Smog Free Tower 1

Air pollution is a serious health problem and crisis in many densely populated cities and countries. We’ve all see pictures of people in places such as Beijing and India where the air is so filled with smog it looks like billowing smoke. But Dutch designer/artist Daan Roosegaarde’s air purifying Smog Free Tower could be a real game changer.

This patented technology, based around indoor air purifier technology, will act like the world’s biggest vacuum cleaner, sucking up all the carbon dioxide and air pollution and producing clean air bubbles in public spaces. The tower, a 23 foot system that filters the surrounding air, will first be built in Rotterdam. Roosegaarde recently launched a Kickstarter campaign to fund this innovative venture. With days yet to go, the campaign has already far exceeded its funding expectations.

Smog Free Tower - compressed carbon

As a great “take-away”, Roosegaarde plans to compress the collected smog particles and create fashionable high-end jewelry. After all, Nature’s compressed carbon results in diamonds. For women there will be Smog Free Rings; for men, Smog Free Cufflinks.

Construction of the 1st tower is imminent. Potential future build sites include Los Angeles, Beijing, Paris and Mexico City – three cities known for their issues with air pollution.This kind of innovation, if adopted by large cities around the world, would go along way to making the air a lot easier to breathe. It’s not the only answer but it’s definitely a really good one.


  • I envision large cylindrical buildings that act like smoke stacks to remove smog from metro areas. The stack effect is real, and could remove the pressure inversions that trap smog in low-lying metro areas. Picture a thirty-foot diameter cylinder five hundred feet tall open at the bottom and top. The warmer air at the bottom would rise and cause an updraft in the interior much like that of a smoke stack, clearing the surrounding air of impurities. A filtration system at the top would serve to capture some of the impurities making the whole system better for air quality. Needs no power.
