Abstract
A method that allows an individual to personally test for contaminants in an air supply. The method consists of purchasing the test kit, placing the test kit on a device that produces air circulation and blowing air through the test kit. The test kit is then removed from the device, repackaged and sent to a laboratory for analysis. The air quality test kit comprises a test filter, a filter backing pad and a support, which together form a device that captures and retains particles carried in an airflow.
