The world's air quality is deplorable. You don't have to look far to find examples of how bad it is. Harder to find are solutions to this problem. Government mandates and clean air initiatives help the goal of reducing greenhouse gases on a larger scale, but these measures do little to help improve the quality of air that you're breathing right now. [Here is information about] three plants that create enough oxygen to keep you alive, even if you're sitting with them inside a sealed container, though we don't suggest you try that. Dypsis lutescens [or] bamboo palm: In addition to removing carbon dioxide from the air and replacing it with oxygen, the bamboo palm filters out air particles that can be dangerous when inhaled. The main particles the bamboo palm removes from the air are xylene, a byproduct of the petroleum and chemical industries, and toluene, a component of car exhaust. It is recommended to have 4 shoulder high palms per person in your house. Sansevieria trifasciata [or] snake plant: Snake plant ... converts carbon dioxide to oxygen at night [and] removes nitrogen oxide, a by-product of car exhaust and fertilizer, and formaldehyde, a component of textile and wood production, from its environment. It is suggested to have 6-8 waist high plants per person per household. Epipremnum aureum [or] devil's ivy: Devil's ivy ... filters out formaldehyde, xylene, and benzene, a byproduct of petroleum combustion, from the air you're breathing. A handful of these 12-inch high plants should do wonders for making the air quality in your house better.
