This pre-school in Shanghai has been fitted with the AirRevival wall units to help keep pollutants at bay. The AirRevival units will work 24/7 to remove pollutants from the air- bringing them back to the surface where the unit is located. Once in place the AR units are completely maintenance free and will only consume a minimal amount of energy. AirRevival is completely noise free so can be run without disturbing ongoing activities in the room. Pre-schools particularly in busy parts of a city are suffering from a cocktail of indoor and outdoor pollutants. Taking control of the indoor air is of great importance for our health and the health of our children.
