NASA has done extensive research on house plants for use as potential air cleaners in space stations and other possible space uses. Their findings are that house plants do improve indoor air quality in some areas. Here's what was found...
Certain house plants were especially good at scrubbing the air of VOCs, off gases from carpeting, particle board and certain types of finishes. Some of the chemicals found to be absorbed were:
One contaminate that plants were not able to absorb is particulate pollutants, such as tobacco smoke; although some of the harmful chemicals are no doubt reduced. Of course the the best reduction plan for cigarette smoke is to keep it out of the home.
House plants that were found to be best were tropical and subtropical variety, which grow in low light conditions on the forest floor. Thus these are well adapted for home conditions where poor lighting is often found.
The soil was also found to a contribute to air quality improvement due to the micro-organisms in it that help to absorb these pollutants as well. So it is recommended that the soil be kept clear of debris, so it can do its job.
