Toulouse is currently experimenting with a brand new urban object, capable of sucking up pollution and emitting clean air. This artificial tree that could soon bloom in our cities is not the first concept of air purifier. There is no shortage of ideas to eliminate fine particles, between green walls and even advertising panels.

An artificial tree

In Toulouse, a start-up has been experimenting since mid-September with a new generation of air purifier and helps fight pollution. This futuristic structure actually incorporates microalgae which devour the co2 like plants do and reject clean air. Kyanos Biotechnologies estimates that this five-meter-high air purifier could “recycle” 200,000 m3 of air each year. Concretely, this artificial tree could capture as much carbon as a hundred real trees. We can discover this new urban UFO until next spring in the pink city.

A green wall

This is a bench. This is also a green wall. Called CityTree, you may have already seen this new street furniture in London, at Picadilly Circus, if not in Amsterdam or Oslo. It is the work of a German company, called Green City Solutions. Attached to a most banal bench, the green wall is four meters high and consists of 1,600 pots of moss and plants. As a result, the street furniture succeeds in capturing fine particles and cleaning the air as much as 275 trees combined. CityTree works with a rainwater tank which allows the plants to be permanently supplied. The irrigation system is powered by solar energy.

A giant tower

The idea is signed by a Dutch designer, Daan Roosegaarde. The inventor believes he imagined the largest air purifier in the world. It must be said that, from the top of its seven meters, its tower is capable of capturing 30,000 m3 of air every hour as well as 75% of fine particles. Thanks to patented ionization technology, the furniture succeeds in transforming molecules into pure air. The Smog Free Tower was first installed in 2016 in Beijing, where the pollution of the Chinese capital precisely inspired the concept of the designer who could not observe the panorama from more than 20 meters due to dense fog. The invention won the future design prize in China last May. The Smog Free Tower has since traveled the world to settle in the Netherlands and Poland.

Deploying new concepts around urban air purifiers has become the workhorse of designer Daan Roosegaarde. His latest invention, which was installed in Monterrey, Mexico, is composed of a special resin capable of transforming pollution fog into healthier air. This technology is based on the principle of photocatalysis: it is the action of the sun’s light rays that allows pollutants to be degraded. This is a new line of research to purify the air without relying on photosynthesis.
