Abstract

There is provided a fit testing method comprising: providing a respirator donned by a wearer; providing a sensor in electrical communication with a sensing element, where the sensor is configured to monitor a particulate concentration parameter of a gas space within the respirator, and a second particulate concentration parameter of a gas space outside the respirator, where the sensor is attached to the respirator such that the respirator such that the weight of the sensor is supported by 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 within the respirator to the particulate concentration parameter outside the respirator.
