Houseplants That Clean the Air

You may have heard that some houseplants can clean the indoor air. Not only is this not an urban myth. But, there has actually been research done to find out what plants are good at reducing common indoor pollutants. The National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA) conducted this study known as The NASA Clean Air Study. According to the findings, in addition to absorbing carbon dioxide and release oxygen, some plants also have the ability to eliminate significant amounts of benzene, formaldehyde, trichloroethylene, xylene, toluene, ammonia from the air. In case you are unfamiliar with these chemicals, here are some sources you should be aware of.

Common sources of benzene in the indoor air include cigarette smoke, exhaust from motor vehicles, smoke from wood burning fires, household products that contain petroleum based chemicals such as glues, paints, furniture wax, and lubricate. Benzene in the indoor air courses asthma, affects blood-forming cells and increases incidents of miscarriage.

Common sources of formaldehyde in home
include building materials, smoking, household products, and the use of un-vented, fuel-burning appliances, like gas stoves or kerosene space heaters. Prolonged exposure to formaldehyde has been linked to some cancers.

Trichloroethylene can contaminate indoor air during home renovations. It is a component of resins, glues, varnish and paint removers, vinyl flooring, and home-improvement products. Acute exposure to Trichloroethylene has been linked to a number of health issues, ranging from minor dizziness all the way up to kidney damage and even death.

Sources of xylene in home include synthetic fragrances and paints. Exposure to xylene can course headaches, dizziness, and allergies.

Common sources of toluene indoors include the use of paints and paint-thinners together with tobacco smoke. Exposure to toluene courses headaches, nausea, irritation of the upper respiratory tract, and even birth defects.

Sources of ammonia include animal waste, fertilizers, and home cleaners. People who have pets indoors and who do not clean up the animal waste may have high levels of ammonia. Ammonia can cause eye irritation and burning of the respiratory tract (including the lungs). Children are at greater risk due to their smaller lung surface-area.

Here is the list of robust, relatively easy to grow houseplants that clean indoor air and eliminate benzene, formaldehyde, trichloroethylene, toluen, xylene, and ammonia.
