This is the Neo P1—a genetically modified houseplant that [French company Neoplants] claims could help combat indoor air pollution. P1 is a modified form of golden pothos—more commonly known as devil’s ivy—one of the world’s most ubiquitous and easy-going houseplants. Although its yellow-green hues appear familiar, P1’s DNA has been tweaked to enhance its ability to extract volatile organic compounds (VOCs) from the air, including formaldehyde, benzene, toluene, ethylbenzene, and xylene, which are prevalent in indoor spaces.

[UC Davis Dean of Engineering Richard] Corsi says that a bedroom of approximately 200 square feet would need as many as 315 individual plants to bring formaldehyde (and other VOC) levels down by 50 percent. To get a 90 percent reduction would require more like 2,800 plants. Scale that up to a whole flat or house, and you’re nurturing a dense jungle.
