Beautiful green houseplants can markedly improve the quality of the air in your home. Place these easy-care beauties in every corner and enjoy!

Sick Building Syndrome (SBS)

Symptoms of SBS, which may include headache, dry cough, itchy skin, fatigue and difficulty concentrating, are alleviated by simply leaving the building.

Our well-insulated, airtight homes keep our utility bills down, but they can contribute to less-than-ideal living conditions. "Sick building syndrome" is a term that the Environmental Protection Agency uses to describe "situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building." Symptoms of SBS, which may include headache, dry cough, itchy skin, fatigue and difficulty concentrating, are alleviated by simply leaving the building.

NASA/ALCA Houseplants Study

In the mid-1980s, a 2-year study by NASA and the Associated Landscape Contractors of America (ALCA) tested the effect of common houseplants on harmful chemicals found in building materials, paints and cleaning products. Science class taught us that plants convert carbon dioxide into oxygen via photosynthesis, and the NASA/ALCA study showed that houseplants can remove benzene, formaldehyde and trichloroethylene from the air.

The study recommends using at least 15 quality houseplants to improve the air quality of an average (under 2,000 square feet) home. For best results, each plant should be grown in a container that is at least six inches in diameter. Most of these plants can be found at your local nursery or even at big-box stores such as Lowe's and The Home Depot.
