Abstract
A method that allows an individual to personally test for contaminants in an air supply. The method consists of purchasing the test kit, mounting the test kit to an existing particulate filter, placing the mounted test kit and particulate filter into the filter housing and blowing air through the test kit. The test kit is then removed from the furnace, repackaged and sent to a laboratory for analysis. The air quality test kit comprises a test filter, a filter backing pad, a support and a pair of end caps. The test filter, the filter backing pad and the support form a device to capture and retain particles carried in an airflow.
