Winner of a Popular Science Invention Award, this device harnesses a plant's natural phytoremediation capabilities to remove volatile organic compounds (VOCs) from the air. Simply place any houseplant inside the container and the integrated, specially designed fan draws in ambient air toxins and circulates them around the plant's leaves and roots, which absorb and metabolize the toxins. Drawing on NASA research, the botanical air purifier removes common household VOCs, including formaldehyde and other toxins emitted from paint, carpets, and adhesives, and recirculates clean air into your home. A study performed by Le Laboratoire of Paris found that the device reduces the concentration of formaldehyde by 50% in 30 minutes, 10 times faster than a traditional air filtration system. A removable tray in the base allows you to easily water the plant and you can adjust the fan speed by turning a dial. Although any plant can be used, the Peace Lily, Madagascar Dragon Tree, Spider Plant, and Aloe are especially effective. For use in rooms of any size. 16 1/4" H x 12 1/4" Diam. (6 lbs.)
