Lungs of the City - Energy-efficient positivity ionization technology for the elimination of urban air pollutants

Lungs of the City is an energy efficient purification technology for large-scale elimination of air pollution in urban areas.

The technology can be invisibly integrated into the urban tissue (tunnels, parkings, public buildings, stations, street furniture), it is based on an energy-efficient positive ionization technology that captures fine particles and ultrafine particles without the use of traditional filtering techniques. Installation of Lungs of the City at air pollution hot-spots, such as parking garages, tunnels, train and bus stations, and busy traffic junctions, has been shown not just to reduce emission at these locations, but also to contribute to the overall improved air quality in the urban environment.
