A dust monitor is disclosed that is suitably deployed in dusty environments and capable of providing near real-time indications of exposure to airborne particulates. The monitor includes a filter and filter assembly made of materials that do not interfere with subsequent instrumental (such as spectrometric) analysis for detecting and/or quantitating an analyte. In some disclosed embodiments, the filter is made of nylon or other material that is readily subjected to thermal destruction prior to spectrometric analysis. The dust monitor also includes a humidity correction feature that permits the filter to be made of ashable organic materials even if those materials are not highly hydrophobic. Transport devices are provided for shipment of the filter and/or filter assembly to an analytical laboratory which prevent loss of particulate matter and which facilitate an accurate analysis procedure.
