The Sansevieria is an ideal plant for indoor spaces because it is a superb air purifier. Studies, including those performed by NASA, have consistently shown the plant to remove toxins such as formaldehyde, xylene, toluene, and nitrogen oxides—which means that industries and workspaces such as automotive plants and shops, aircraft plants, plywood, carpeting, paint makers and sellers, printing, and offices, where these chemicals abound in the products produced and used, would greatly benefit by keeping several Sansevieria around. NASA, whose study purposed to determine how to clean the air in space stations, recommends at least 15 to 18 medium-to-large size plants for a 1,800 square-foot home.
The plant purifies air by absorbing toxins through the leaves and producing pure oxygen. In fact, the Sansevieria is an ideal bedroom plant. Whereas most other plants release carbon dioxide at night (in the absence of photosynthesis), the Sansevieria continues to produce oxygen.Kudos to :http://ithabise.hubpages.com/hub/sansevieria-snake-plant-allergy
