How to grow your own fresh air


From Ron Epstein

Kamal Meattle reported the results of his efforts to fill an office building with plants (video), in an effort to reduce headache, asthma, and other productivity-sapping aliments in thickly polluted India. After researching NASA documents, he concluded that a set of three particular common, waist-high houseplants—areca palm, Mother-in-Law’s Tongue (shown above), and Money Plant—could be combined to scrub the air of carbon dioxide, formaldehyde and other pollutants.

At about four plants per occupant (1200 plants in all), the building’s air freshened considerably, and the health and productivity results were staggering. Eye irritation dropped by 52 percent, lower respiratory symptoms by 34 percent, headaches by 24 percent and asthma by 9 percent. There were fewer sick days, employee productivity increased, and energy costs dropped by 15 percent.

Next stop: a larger-scale experiment in a 1.75-million-square-foot office tower, featuring over 60,000 plants.
