Abstract (en)
[origin: WO2020260550A1] A plant-based air filtration device (100), and its use for filtering ambient air for example of road walls, train walls or on building façades, parking slopes, tunnel exits or building interiors, wherein ambient air entering through the sediment filtration means (70) is accelerated by the airflow generation means (60) vertically towards the air distribution duct (30) thereby pushing the air through the front openings of the air distribution duct (30) and distributing the water from the water distribution means (22) laterally to and within the plant-based layer (15) of the plant- based multi-layer materials (12).
