NASA houseplant study : Adding plants to your home may do more than make the space look greener. Some houseplants have attracted scientific attention for their potential role in improving indoor air quality, giving people another reason to bring a little more nature indoors.
NASA studied common indoor plants to find out whether they could help remove certain organic chemicals from indoor air. The research, titled “A Study of Interior Landscape Plants for Indoor Air Pollution Abatement,” examined the removal of benzene, trichloroethylene and formaldehyde using plants placed inside sealed experimental chambers.
