Get Some Fresh Air

Get Some Fresh AirDo you ever find yourself or your co-workers sneezing uncontrollably, complaining of air filters long overdue for a change? Want an easy, sustainable solution? Invest in an office plant.

Indoor plants reduce air pollutants and provide more oxygen for you. Since the 1970s, retired NASA scientist B.C. Wolverton, now founder of Wolverton Environmental Services, Inc., has studied the effectiveness of indoor plants at cleaning the air by absorbing potentially harmful gases, such as formaldehyde, benzene, and carbon monoxide.

Wolverton published his most notable findings in How to Grow Fresh Air: 50 Houseplants That Purify Your Home or Office. Some plants that made the list include bamboo palms, Chinese evergreens, English ivy, dracaena, peace lilies, philodendrons, spider plants, and pothos. Read more information on the NASA-sponsored research.

So how do you decide which plant will work best for your workspace? Here are some guidelines:

  1. Measure the amount of space allowed for your plant.
  2. Determine the amount of care you will be able to give your plant.
  3. Determine the conditions of your space (amount of sunlight, average temperature).
  4. Determine your plant budget.
  5. Choose a plant(s) specific to your needs and space conditions.
  6. Purchase your plant(s) from a local nursery or farmers market.

If you find your plant options overwhelming, here are general characteristics to keep in mind:

  • Plants with larger leaves can absorb more light so they do not need as much as plants with smaller leaves.
  • Plants that require little maintenance, especially less watering, are ideal for those days when you’re not in the office.
  • Avoid plants that need humidity — offices tend to be dry.
  • Avoid flowering plants in case of co-worker allergies.

To make it easy for you, UMB Go Green has provided a table of some of the most effective air-purifying plants:
