What it does
We tackle air pollution and create green urban places by using moss as a natural fine dust filter and combining it with smart IoT technology.
The air flows through the vertical moss mats and is cleaned and cooled in the process. Sensors measure the activity of the mosses and ensure that they are optimally cared for. The moss filter provides cooled and clean air for all around. The air flows through the vertical moss mats and is cleaned and cooled in the process.
