Due to improved construction methods, buildings are better sealed to maximize energy efficiency. These air pollutants can cause problems for inhabitants especially during the winter when people are forced to spend a great deal of time indoors. Houseplants are currently receiving a lot of attention on improving indoor air quality. The gases most often studied include formaldehyde, benzene, xylene, toluene, ammonia, acetone, methyl alcohol, ethyl acetate, and trichlorethylene. The amount of purification depends on the plant being tested.
Different houseplants purify different toxic chemicals to differing degrees.
Not only are these houseplants a beautiful addition to the interior landscape, they can be beneficial as well. Prepared by Cindy Haynes , Department of Horticulture Iowa State University , Ames, Iowa. This information subject to a usage policy .
