ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention pertains to a method and a test kit to test for contaminants in an indoor air supply. More particularly, the invention pertains to a method and a test kit that allows an individual such as a homeowner to test for contaminants contained in an indoor air supply by utilizing the existing heating ventilation system.
There is always a concern over whether the presence of contaminants exist in the air supply of an indoor room. Such concern arises because human or animal inhalation of contaminants may lead to respiratory infections and diseases. Additionally, fungus growing in a room can corrode metal surfaces, create an unappealing sight, become a serious fire hazard, and increase energy costs due to lower performance levels of air delivery systems. Contaminants that may be inhaled include fumes, fibers, allergens, fungi, bacteria and any other matter that poses a risk to indoor air quality.
The detection of contaminants in an indoor environment is crucial because most people cannot visually tell whether a room is contaminated. In addition, indoor rooms often do not have the appropriate ventilation to eliminate contaminants without the aide of experts. Therefore, various techniques have attempted to provide a means for detecting contaminants.
One technique is to call upon industrial hygienists. An industrial hygienist will visit a particular site and perform air monitoring tests utilizing special equipment. This technique, however, is labor intensive and often cost prohibitive, particularly for a residential homeowner.
A simple technique to detect the presence of contaminants in an indoor air supply is presently not available. The present invention is directed at a simple, inexpensive test kit and method to detect the presence of contaminants in an indoor air supply.
BRIEF SUMMARY OF THE INVENTION
The invention is a method and a device that allows an individual to test for contaminants in an indoor air supply. The homeowner purchases the test kit which includes a test filter and a support. The test filter is made of a material that will capture and retain contaminants carried in the air. The support includes a central opening to which the test filter is attached. The homeowner then removes the particulate filter from the heating and ventilation system so that the test filter and support can be mounted onto the particulate filter. The test filter is mounted onto the particulate filter with the help of the support. The mounted support, test filter and particulate filter are returned to the filter housing. The blower of the heating and ventilation system is then operated for a predetermined amount of time. The blower is then turned off and the support and test filter are removed from the particulate filter, repackaged and sent to a laboratory for analysis.
