Green walls remove NO2 from the air
The study showed that Aerogation walls, which purify air naturally without filters or sequestration, remove an average of 62.4 percent of NO2 from polluted air. The results demonstrated that the technology is effective at cleaning polluted air, as is already being done with test walls in the City of London.
The University of Texas earlier this year erected its first green wall. See it in action in the video below.
