List of air-filtering plants
The first list of air filtering plants was compiled by NASA as part of the NASA Clean Air Study,[1][2] which researched ways to clean air in space stations. As well as absorbing carbon dioxide and releasing oxygen, as all plants do, these plants also eliminate significant amounts of benzene, formaldehyde and/or trichloroethylene. The second and third list are from Dr. B.C. Wolverton's book[3] and paper [4] and focus on removal of specific chemicals.
The recommendation of NASA is to use 15 to 18 good-sized houseplants in six- to eight-inch (203 mm) diameter containers in a 1,800-square-foot (170 m2) house.[citation needed]

[edit] Foliage
Most of the plants on the list evolved in tropical or subtropical environments. Due to their ability to flourish on reduced sunlight, their leaf composition allows them to photosynthesize well in household light.
