Abstract
An air delievery monitoring system covers an aperture of an air duct with an insert having a bore. A filter element in communication with the inside of that air duct through that bore is made accessible from outside of that duct. Air escapes from the duct through the bore in the insert to the filter element which traps contaminants in such air for subsequent laboratory analysis. The filter element is preferably encapsulated in an apertured filter element housing which is mounted in the insert in communication with its bore. After removal of that housing from the insert, the contaminated filter element can be transported or sent to the laboratory for the performance of several analyses thereon.
