Based on preliminary evaluations... the use of common indoor plants for indoor air purification and revitalization, ALCA joined NASA to fund a study of about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several key pollutants associated with indoor air pollution.

Each plant type was placed in sealed, plexiglass chambers in which chemicals were injected. Philodendron, Spider plant and the Golden pothos were labeled as the most effective in removing formaldehyde. Flowering plants such as the Gerbera daisy and Chrysanthemums were rated superior in removing benzene from the chamber atmosphere.

Other plants demonstrated to be effective air purifiers include the Bamboo palm, Peace lily, Ficus, Dracaena massangeana cane, Mother-in-Law's tongue (Sanseveria), English Ivy and Chinese evergreen species.

"Plants take substances out of the air through the tiny openings in their leaves", Wolverton said. "But research in our laboratories has determined that plant leaves, roots and soil bacteria are all important in removing trace levels of toxic vapors"
