The NASA Clean Air Study is led by National Aeronautics and Space Administration (NASA) in collaboration with the American Landscaping Contractor (ALCA). The results show that certain common indoor plants can provide a natural way to remove toxic substances such as benzene, formaldehyde and trichlorethylene from the air, helping to neutralize the effects of sick building syndrome.
The first list of air filtration plants was compiled by NASA as part of a clean air study published in 1989, which examines ways to clear the air at the space station. As well as absorbing carbon dioxide and releasing oxygen, as all plants do, this plant also removes large amounts of benzene, formaldehyde and trichlorethylene. The second and third lists are from B and B. Wolverton's book and papers focusing on the removal of certain chemicals.
NASA researchers suggest efficient air cleaning is done with at least one plant per 100 square feet of home or office space. More recent studies have shown that micro-organisms in the pot (soil) mixture of plant pots remove benzene from the air, and that some plant species also contribute to the elimination of benzene.

Foliage
Most of the plants on the list come from tropical or subtropical environments. Because their ability to thrive in sunlight is reduced, their leaf composition allows them to photosynthesize well in household light.
