How to Test

Using a test kit that meets the EPA requirements, place the test kit in the lowest level of the home suitable for occupancy, at least 20 inches above the floor. The test kit should not be placed in the bathroom or kitchen, where the humidity and use of fans could effect the test results. If a short term test lasting less than 4 days is conducted, doors and windows should be closed 12 hours prior to and throughout the testing period. If the test lasts up to 7 days closed house conditions are recommended. Short term testing should not be done during severe storms or periods of unusually high winds. Place the test kit in an area that will not be disturbed and away from drafts, high heat, high humidity and exterior walls that may have windows or doors. Carefully follow the directions in the test kit and leave it in place for the time period noted in the instructions.
