Stanley Kays, the lead researcher at University of Georgia, said some indoor plants have the ability to effectively remove harmful VOCs from the air and not only improve physical health, but also someone’s wellbeing.
Adding these plants to indoor spaces can reduce stress, increase performance at work and reduce symptoms of ill health.
The research team tested 28 common indoor ornamental plants for their ability to remove five volatile indoor pollutants.
Of the species tested, purple waffle plant (Hemigraphis alternata), English ivy (Hedera helix), waxy leaved plant (Hoya carnosa) and Asparagus fern (Asparagus densiflorus) were rated best for removing air pollutants.
The purple heart plant (Tradescantia pallida) was rated superior for its ability to remove four of the VOCs.
Prof Kays, writing in the journal HortScience, said: “The volatile compounds tested in this study can adversely affect indoor air quality and have a potential to seriously compromise the health of exposed individuals.”
The study concluded that simply introducing common ornamental plants into indoor spaces has the potential to significantly improve the quality of indoor air.
