We saw how adding plants into our home could purify our indoor air quality. In most cities there is more pollution inside our home than outside, as trees and plants are constantly cleaning the air and act as filters.
NASA tested popular plants for their ability to create oxygen and filter common toxins like trichloroethylene (found in varnishes, paints, and adhesives), formaldehyde (present in carpets, furniture, and foam insulation), and benzene (found in plastics, synthetic fibers, and detergents) to purify the air astronauts breathe. Now there is even more research.

If you are worried about or sickened by your indoor air quality? Fill your home or office with ferns.
Indoor volatile organic compounds (VOCs) such as formaldehyde can contribute to allergies, asthma, headaches, and so-called “sick building syndrome.”
Formaldehyde is a major contaminant of indoor air, one that “out-gasses” from particle board, carpet, window coverings, paper products, tobacco smoke, and other sources.
The World Health Organization estimates that toxic indoor VOCs represent a serious health problem that’s responsible for more than 1.6 million deaths annually and a shocking 2.7 percent of the “global burden of disease”.
Scientists had previously discovered the benefits of using plants to absorb and metabolize gaseous formaldehyde a tactic known as “phyto-remediation”
Now, a team of scientists from South Korea and the University of Georgia have ranked 86 plants in order of effectiveness at removing volatile formaldehyde from indoor air.
The 86 candidates came from five families: ferns, woody foliage plants, herbaceous foliage plants, Korean native plants, and herbs.
The phytoremediation potential of each plant was measured by exposing the plants to gaseous formaldehyde in airtight chambers made of inert materials, and then measuring the rate of removal.
Ferns had the highest formaldehyde removal efficiency of the five classes of plants tested, with Japanese royal fern (Osmunda japonica) found most effective a whopping 50 times better than the least efficient species (D. deremensis).
The other top performers were Sweet Lavender (Lavandula), Geranium (Pelargonium), Spikemoss (Selaginella tamariscina), Hare’s-foot fern (Davallia mariesii), Guava (Polypodium formosanum) and Spider fern (Pteris dispar, Pteris multifida).
Lead author Kwang Jin Kim cited the benefits in an understated way: “It is evident from our results that certain
species have the potential to improve interior environments and, in so doing, the health and well-being of the inhabitants.”
For Dr. Ki it seems that we should all place some ferns, lavender, and geranium around our homes and offices.

San Francisco Green Living Examiner’s Note: Place your plants strategically near your desk, bed or otherwise where you sit for long periods. Create a cleaner breathing space.
