Are Houseplants Good for the Air Quality in Your Home?

In 1989 NASA did a study on air quality. They wanted to explore ways to improve air quality is small, unventilated spaces. Called the Clean Air Study, they found that certain indoor plants could improve air quality by removing certain toxins. Some helpful plants mentioned in the study included the spider plant, English ivy, and philodendron, among others. The World Health Organization estimates that 3 million people die prematurely each year due to diseases caused by indoor air contamination. These plants have been shown to remove toxins from the air such as formaldehyde, benzene, and xylene, common chemicals released from building materials and even carpet. 

While these plants generally require low or indirect sun, their soil and water needs vary. Some may be toxic to animals as well, so it’s best to research your plants before making them a part of your home.
