Much of the research on the benefits of indoor plants has been done by NASA scientists researching ways to create suitable space station habitats. All indoor plants (flowering or not) are able to purify indoor air to some degree through their normal photosynthesis processes. But some were found to be more beneficial than others in removing harmful household toxins, even removing 90% of chemicals in the air in only twenty-four hours!

The three main household toxins of concern are:

  • benzene
  • formaldahyde
  • trichloroethylene
