Remove Dangerous Pollutants Using House Plants


We all know plants and nature have many different uses, both in health and healing. However, did you know that certain types of plants can actually purify the air in your home? NASA did a study back in 1989 that still holds up very well today.

The study was conducted by B. C. Wolverton Ph.D., Anne Johnson M.S., and Keith Bounds M.S. at the Stennis Space Center in Mississippi. Wolverton and his team set out to discover various plant species that would reduce pollutants in the air during space travel. Obviously being stuck in a completely sealed room is different than your own home, however if you spend a lot of time at home or in your office, these plants may be a great idea to help keep your air at its highest natural quality.

The chemicals focused on in the experiment were Benzene, Trichloroethylene, and Formaldehyde.

benzeneBenzene can be found in gasoline, furniture wax, glue, detergents, paints, and pesticides. According to the Center for Disease Control’s website, this dangerous pollutant is capable of causing health problems ranging from head aches, dizziness, and rapid/irregular heart beat, to unconsciousness, or even death. The CDC continues to say long term exposure may cause low red blood cells, harmful effects to your bone marrow, irregular menstrual cycles, and even cancer.


TrichloroethyleneTrichloroethylene is mostly found in solvents to remove grease from metal parts and as a chemical that is used to make other chemicals, especially the refrigerant, HFC-134a. Most commonly causing air pollution in textile and dry cleaning facilities. The biggest risk contamination to normal households is through their water supply. The CDC’s website indicates the exposure health risks include headaches, dizziness, and sleepiness; large amounts of trichloroethylene may cause coma and even death.


FormaldehydeFormaldehyde is found in household products such as glues, paints, caulks, pesticides, cosmetics, and detergents. Here is a list of specific products containing Formaldehyde. The CDC states that formaldehyde can cause health affects from sore throat and nose bleeds, to cancer or death depending on exposure.


Other common household contaminates include volatile organic compounds, airborne biological pollutants, carbon monoxide and nitrogen oxides, pesticides and disinfectants (phenols), and radon.

These air borne pollutants should have no place in your home, so it is important to take precautions to reduce your families exposure to these chemicals. Make sure to be conscious of the cleaning and paint products you use in your home. This document has excellent home cleaner recipes, which are non toxic and safe for your family and pets.
