Stelo – A breath of fresh air

A product service system for healthier schools

Year /

In the city of Milan, more than a thousand schools are exposed to nitrogen dioxide concentrations higher than the legal limit of 40 μg/m³, which is already 4 times the WHO’s recommendation. The Stelo System includes innovations such as Stelo Air, a modular plant-based indoor air purifier that is mounted on classrooms walls. It can efficiently clean an average-sized classroom (65 m²) air in 15 minutes with almost no electricity.

Designed with public indoor spaces in mind, it aims to create a safe environment for children to grow and learn about nature, also thanks to the eco-curriculum to instil awareness of environmental standards.
