The University of Georgia published a research paper – Screening Indoor Plants for Volatile Organic Pollutant Removal Efficiency – in which they conducted research on which houseplants removed harmful toxins from the air. Among the Top 5 Indoor Air Cleaning Plants was Hoya carnosa! Along with four other Top 5 plants, Hoya carnosa had the highest removal rates for all five volatile organic compounds introduced in their experiments.
Study leader Stanley J. Kays of the University of Georgia in Athens placed plants in gas-tight glass jars, exposing them to benzene, octane, toluene and alpha-pinene. The researchers analyzed air samples and then classified plants as superior, intermediate and poor in their ability to remove the five volatile organic compounds from the air.
“The volatile organic compounds tested in this study can adversely affect indoor air quality
and have a potential to seriously compromise the health of exposed individuals,” Kays said in a statement.
Kays said benzene and toluene are known to originate from petroleum-based indoor coatings, cleaning solutions, plastics, environmental tobacco smoke and exterior exhaust fumes seeping into buildings; octane from paint, adhesives and building materials; TCE from tap water, cleaning agents, insecticides and plastic products; and alpha-pinene from synthetic paints and odorants.
