These "Artificial Trees" Can Filter as Much Pollution From the Air as 275 Natural Trees

Developed in Germany, the CityTree is a mobile structure that incorporates mosses and urban furniture to create a possible solution to the polluted air of urban centers.

Rectangular, trunkless and flat, this "tree" basically consists of a large vertical panel, a wall of mosses which, according to its creators, has the capacity to absorb the same amount of nitrogen dioxide and microscopic particles from the air as 275 natural trees.
