Co-designed by Dutch artist Daan Roosegaarde, the seven-metre high tower sucks in dirty air like a giant vacuum cleaner. Ion technology then filters it, before returning bubbles of smog-free air through the tower’s vents. It is able to clean 30,000 cubic metres of air an hour, according to Roosegaarde.
Clean air is a precious commodity. A new study has found that more than three million people die prematurely due to air pollution each year. This is projected to double by 2050 if the problem isn’t tackled.
“The smog-free tower contributes to a debate that shouldn’t be confined to politics,” says Rotterdam’s mayor, Ahmed Aboutaleb. “Air pollution is a matter that affects us all, and it requires a serious discussion. But we do need innovators like Daan Roosegaarde to start the conversation at another level.”
