In the 80’s NASA did an interesting study on cleaning indoor air pollutants. What they found was that some plants clean 3 common indoor pollutants, trichloroethylene, benzene, and formaldehyde from the air fairly well.
Formaldehyde is common everywhere, its in building materials, and household products like cleaning products, plastic shopping bags, paper towels. Benzene is a common solvent which is found in oils, plastic, detergents and paints. Trichloroethylene is used in paints, adhesives, inks, and varnishes.
Research was conducted on nineteen common household plants. The results showed that they are good at clearing up these pollutants; however some worked better overall, while others were more effective in getting rid of specific pollutants.
I have listed below these findings by the chemical they were best at cleaning up.
Benzene – English ivy, gerbera daisies, pot mums, peace lily, bamboo palm, and Mother-in-law’s Tongue were found to be better
Trichloroethylene – peace lily, gerbera daisy, and bamboo palm were good.
Formaldehyde – bamboo palm, Mother-in-law’s tongue, dracaena warneckei, peace lily, dracaena marginata, golden pathos, and green spider plant were all good.
The study found the following 10 planets to be the most effective at overall of clearing indoor air pollution.
•Bamboo Palm (Chamaedorea Seifritzii) •Chinese Evergreen (Aglaonema Modestum)
•English Ivy (Hedera Helix) •Gerbera Daisy (Gerbera Jamesonii)
•Janet Craig (Dracaena “Janet Craig”) •Marginata (Dracaena Marginata)
•Mass cane/Corn Plant (Dracaena Massangeana)
•Warneckii (Dracaena “Warneckii”) •Mother-in-Law’s Tongue (Sansevieria Laurentii)
•Pot Mum (Chrysantheium morifolium) •Peace Lily (Spathiphyllum)
