Air filtering plants
compiled by NASA as part of the NASA Clean Air Study, which researched ways to clean air in space stations. As well as absorbing Carb-diox. and releasing oxygen, as all plants do, these plants also absorb significant amounts of benzene, formaldehyde and/or trichloroethylene.

Most of these plants are tropical or subtropical. Due to their ability to flourish on reduced sunlight, their leaf composition allows them to photosynthesize well in household light.
The recommendation of NASA is to use 15 to 18 good-sized houseplants in six- to eight-inch diameter containers in a 1.800 square-foot house. The amount of exposed surface soil is also important, as microorganisms in the soil consume trace amounts of airborne toxins as well
