Grow Clean Fresh Air
Plants "Clean" Air inside Our Homes!
Colorado State University, Denver County Cooperative Extension, Master Gardener 1999-2007



Houseplants are the latest word in household cleaning. Research now shows that houseplants play an important role in cleaning the air we breath, both indoors and out.

Plants produce their own food through a process called photosynthesis. This means they take in carbon dioxide from the atmosphere and release oxygen. Photosynthesis "cleans" our air by absorbing carbon dioxide and by taking in certain other pollutants, as well.

A team of National Aeronautics and Space Administration (NASA) researchers lead by Dr. Bill Wolverton tested the effect of fifteen house plants on three pollutants known to be present in spacecrafts. These same three pollutants--benzene, formaldehyde and trichloroethylene--are present in homes and office buildings. They occur because they are emitted from furnishings, office equipment and some building materials.

Under controlled conditions, in the NASA study, certain houseplants were found to remove as much as 87 percent of indoor air pollutants within 24 hours.

Until recently, indoor air pollution was not considered a health threat; most homes and public buildings leaked so much that air often was replaced every couple of hours. But during the 1970's, after energy shortages occurred, more and more of us began to insulate our houses and office buildings to conserve energy and lower heating and cooling costs. As a result, indoor air might linger for five hours or more allowing pollutants to accumulate.

Researchers are just beginning to understand how indoor pollutants such as cigarette smoke, for example, can harm humans. Effects range from skin and eye irritations to headaches and allergies. Some of the pollutants may be carcinogenic. According to the NASA study, the plants listed below proved effective in removing certain indoor air pollutants


Pollutant Source Plants Removing Pollutant
Benzene Inks, oils, paints, plastics, rubber, dyes, detergents, gasoline, pharmaceutical,
tobacco smoke, synthetic fibers
English Ivy, Dracaena marginata, Janet Craig, Warneckei, Chrysanthemum, Gerbera Daisy, Peace lily
Formaldehyde Foam insulation, plywood, pressed-wood products, grocery bags, waxed paper, fire retardants, adhesive binders in floor coverings, cigarette smoke, natural gas Azalea, Philodendron, Spider plant, Golden Pothos, Bamboo palm, Corn plant, Chrysanthemum, Mother-in-law's tongue
Trichloroethylene Primarily used in the metal degreasing and dry cleaning industries; also in printing inks, paints, lacquers, varnishes, adhesives Gerbera Daisy, Chrysanthemum, Peace lily, Warneckei, Dracaena marginata
The NASA researchers suggest that for the test plants to be effective "air cleaners" it is necessary to use 1 potted plant per 100 square feet of home or office space. Indeed, it would appear that plants have many useful qualities, including one of making our indoor air cleaner to breath.*
