provide beauty and interest, bringing a bit of leafy, green, outdoorsy ambiance to the indoor environment. However, plants play an even more important role by helping to improve air quality in your home.
Research by a team of NASA scientists indicates that these helpful houseplant air purifiers clean the air during the natural process of . The pollutants, absorbed by the leaves, are eventually broken down by microbes in the soil. Although all plants are believed to be beneficial, researchers discovered that some plants are especially effective at removing dangerous pollutants.
Best Houseplants to Purify Air
Air purifying houseplants include several familiar, inexpensive, easy-to-grow houseplants. For example, and are superior air purifiers when it comes to removing formaldehyde, a colorless gas released by glues and resins in particle board and other wood products. Formaldehyde is also emitted by cigarette smoke and fingernail polish, as well as foam insulation, some draperies, synthetic carpeting and household furnishings.
are powerhouses that remove formaldehyde, as well as carbon monoxide and common pollutants like benzene and xylene. These low-maintenance plants are easy to propagate by planting the small, attached plantlets, or “spiders.” Place spider plants in rooms where carbon monoxide is likely to concentrate, such as rooms with fireplaces or kitchens equipped with gas stoves.
Blooming plants, such as and , help remove Tetrachloroethylene, also known as PCE or PERC, a chemical used in paint removers, water repellents, glues and dry cleaning solvents.
Indoor palm trees, like , and dwarf date palm, are good all-around air cleaners. provide an additional benefit by increasing the level of humidity in the air.
Other general-purpose air purifying houseplants include:
- Queen fern
Most types of and , along with succulents such as and (snake plant or mother-in-law’s tongue), help purify the air as well.
The attractive, all-purpose plants are helpful anywhere in the home, but do the most good in rooms with new furniture, paint, paneling or carpeting. NASA studies indicate that 15 to 18 healthy, vigorous plants in medium-size pots can effectively improve air quality in an average home.
