The use of indoor plants for cleansing toxins from air is getting more sophisticated. A team of young researchers from Purdue has won a student design competition with an entry encompassing elements of resource sustainability, interior design, horticulture, and engineering. The biowall, based on research done by a former NASA scientist, is part of a building’s heating and cooling system. As air moves through the return air duct where the plant wall with attractive living plants is located, it moves slowly enough for air purification to take place. The tricky part, the team said, was keeping the roots moist.
