Dutch inventor Daan Roosegaarde designed a revolutionary tool for urban health - a billboard that cleanses smog.

Multiple pollution-cleansing billboards are currently set up in Monterray, Mexico. Each ad space has been coated with a specialized resin that attracts nearby air pollutants and converts them into oxygen when exposed to direct sunlight.
The photocatalytic nanotechnology works similarly to the mineral-based surface treatment that allows these GUNRID curtains from IKEA to cleanse airborne pollutants from indoor spaces.
The billboard generates the same amount of clean air as 30 trees every 6 hours and it can function for up to five years.
It was great to work with the [UDEM] students and take a problem and transform it into a potential. I am really proud to see them go from academic research to a real project. I do not believe in utopia—a perfect solution—but protopia: step-by-step improving reality. ~ Inventor Daan Roosegaarde
