Eco-friendly House Plant-ไม้ประดับขจัดพิษ
gave us the knowledge of Eco-friendly or GREEN House Plant

In the late 1980s, a study by NASA and the Associated Landscape Contractors of America (ALCA) resulted in excellent news for homeowners and office workers everywhere. The study concluded that common houseplants such as bamboo palms and spider plants not only make indoor spaces more attractive, they also help to purify the air!

The study was conducted by Dr. B.C. Wolverton, Anne Johnson, and Keith Bounds in 1989. Newer homes and buildings, designed for energy efficiency, are often tightly sealed to avoid energy loss from heating and air conditioning systems. Moreover, synthetic building materials used in modern construction have been found to produce potential pollutants that remain trapped in these unventilated buildings.

The study showed that many houseplants also remove harmful elements such as trichloroethylene, benzene, and formaldehyde from the air.

For example, English ivy, gerbera daisies, pot mums, peace lily, bamboo palm, and Mother-in-law’s Tongue were found to be the best plants for treating air contaminated with Benzene. The peace lily, gerbera daisy, and bamboo palm were very effective in treating Trichloroethylene.

Additionally, NASA found that the bamboo palm, Mother-in-law’s tongue, dracaena warneckei, peace lily, dracaena marginata, golden pathos, and green spider plant worked well for filtering Formaldehyde.

From this study, House Plants in Thailand which is recognized as Eco-friendly House Plants shown as followings:
