Abstract: A method of fit testing includes providing a respirator donned by a wearer, providing an aerosol generator with a known aerosol output parameter, providing an enclosure that is physically supported around the wearer's head, where the aerosol generator delivers aerosol with the known aerosol output parameter that is at least partially contained within the enclosure around wearer's head, providing a sensor in electrical communication with a sensing element, where the sensor is operably connected to the respirator, and where the sensor is configured to monitor a particulate concentration parameter within the respirator, and providing a reader configured to communicate with the sensor, where the reader is configured to provide a respirator fit parameter based on a comparison of the particulate concentration parameter to the known aerosol output parameter.

Abstract: There is provided a fit testing method comprising: providing a respirator donned by a wearer; providing a first sensor, where the sensor is configured to monitor a particulate concentration parameter within the respirator, where the first sensor is attached to the respirator such that the weight of the first sensor is supported by the respirator; providing a second sensor configured to monitor a particulate concentration parameter outside the respirator; and providing a reader configured to communicate with the sensor, where the reader is configured to provide a respirator fit parameter based on a comparison of the particulate concentration parameter within the respirator to the particulate concentration parameter outside the respirator.
