| | Plants Actually Clean the Air! |
 | | Indoor air pollution, a problem resulting from intense energy-efficiency in buildings, consists of particles and gases trapped in building air which is not circulated or filtered properly. |
 | | Further research is determining the efficacy of indoor plants in cleaning up larger particle common indoor air pollutants, such as asbestos; pesticides; carbon dioxide, carbon monoxide, and other gases; chemicals from detergents, solvents, and cleaning fluids; fibers released from clothing, furnishings, draperies, glass, carpets, and insulation; fungi and bacteria; and tobacco smoke. |
 | | Trees strategically planted to shade homes can generate a 10 to 50 percent savings in cooling expenses and 4 to 22 percent savings of heating costs (as wind breaks), although the extent of savings is determined by tree type, planting location, and climatic vacations. |
