Constantly have itchy eyes, nose and throat? Is it hard to concentrate? Experience dizziness or nausea? You might be suffering from Sick Building Syndrome (SBS). The EPA defines SBS as "situations in which building occupants experience acute health and comfort effects that appear linked to time spent in a building, but no specific illness or cause can be identified." The main factors that contribute to SBS are impurities and toxins found in the air. These contaminants are mainly found within newer buildings that have better sealing and insulation. Although this professional sealing leads to a more energy-efficient home, it has the result of trapping pollutants within the circulating air of the homes ventilation system.
So how can you remove the contaminants from your home while remaining cost effective?

According to NASA research, having houseplants is a key way to filter the toxins found within the home. While plants go through the process of photosynthesis they pull carbon dioxide from the atmosphere and convert it to oxygen. In addition to the plants natural cycle, NASA found that houseplants were also able to eliminate large amounts of trichloroethylene, benzene and formaldehyde. Trichloroethylene is commonly found in paints, adhesives, and varnishes. Benzene is a part of tobacco smoke, detergents, and gasoline. Formaldehyde is usually located within household cleaners, carpeting, and foam insulation. Since all of the items listed are very common to the home, it is vital to remove these toxins in the most efficient and environmentally safe way possible. NASA's research of plants that removed the most toxins is listed below along with their individual scores:

The research suggests that for every 100 square feet an indoor plant should be placed. Each plant should be potted in a 5-6 inch container to maximize the efficiency of air cleaning. On average, a single houseplant will show improvement in air quality within a 24 hour period.
