We grow fresh air - with moss, naturally. More than half of humanity lives in cities – and the trend is rising. Cities are clearly the living space of the future. And yet our most important resource, the air we breathe, is in many places so polluted that breathing is harming our health. In the future we have in mind, fresh air in urban areas is available to everyone. That’s why we developed the world’s first regenerative bio-tech filters for verifiable improvements in air quality. #WeGrowFreshAir with CityTree, CityBreeze and WallBreeze.
