Houseplants for Clean Air

We all know how important it is to help clean and maintain air quality outside; but many people don’t realize that indoor air pollution is one of the fastest growing environmental problems we face today. The alarming fact is that electrical equipment, furniture, cleaning products and building materials all release trace amounts of toxins such as carbon monoxide, formaldehyde and benzene (a known carcinogen), into our homes and offices.

Houseplant Helpers

Houseplants are a wonderful way to beautify and cheer up your indoor spaces, but the fact that they are exceptional air purifiers is often overlooked. Houseplants improve air quality by absorbing toxins along with carbon dioxide. Within their leaves, microorganisms break down the chemicals naturally. The plants then release fresh, clean oxygen for us to breathe.

Studies have been done to measure the amount of pollutants filtered out by common houseplants. In some studies the plants were able to remove up to 80% of the pollutants! Some research even showed that not only were the leaves doing the work, but the roots also helped in the process.

One study conducted by NASA suggests using one houseplant per 100 square feet of floor space for the most effective pollution control.

Common Pollutants and their Sources

• Formaldehyde:
  Carpeting, pressed wood, foam insulation, fiberwood products (such as paneling), hair sprays, wax paper, paper towels and various cleaning products.
• Benzene:
  Glue, Spot removers, oils, paint, inks, varnish, rubber, plastic products, detergents, dyes, gasoline and paint stripper.
• Hydrocarbons:
  Vinyl products (such as furniture and flooring), detergents and fabric softeners.
• Trichloroethylene:
  Inks, paint, lacquer, varnishes, adhesives (such as rubber cement, epoxy or spray mount).
