“These three household plants will certainly improve your indoor air quality, even if you don’t have quite so many. If you’re not satisfied with just three options, other new research has identified five “super ornamentals” that demonstrated high effectiveness of contaminant removal.
These include the purple waffle plant (Hemigraphis alternataa), English ivy (Hedera helix), variegated wax plant (Hoya cornosa), Asparagus fern (Asparagus densiflorus) and the Purple heart plant (Tradescantia pallida). Remember to check all plants for toxicity to dogs and cats via the American Society for the Prevention of Cruelty to Animals.
Of the 28 plants tested, these five were effective at reducing levels of a number of common household VOCs, including benzene, toluene, octane, alpha-pinene and TCE. The work, funded by the University of Georgia’s Agricultural Experiment Stations, was published in the August 2009 issue of HortScience. “
