Abstract: A system and method for completing fit tests on a respirator mask, and indicating end of service life for one or more elements of the respirator mask. The system includes an electronics module mounted on the interior of the face mask. The module includes a pressure sensor, and possibly other sensors, such as gas sensors, temperature sensors, and humidity sensors. The module may detect the pressure on the interior of the mask during fit tests to detect any leaks in the mask. The module may be used for positive and negative pressure fit tests. Additionally, the module may include one or more indicators (lights, sounds, vibrations) for alerting a user during a fit test. The module may also detect end of service life by analyzing the sensor data, and may indicate end of service life to the user.

Abstract: Embodiments relate generally to systems and method for completing fit tests on a respirator mask, and indicating end of service life for one or more elements of the respirator mask. Applicants propose a system comprises an electronics module mounted on the interior of the face mask, wherein the module comprises a pressure sensor, and possibly other sensors, such as gas sensors, temperature sensors, and humidity sensors. The module may detect the pressure on the interior of the mask during fit tests to detect any leaks in the mask. The module may be used for positive and negative pressure fit tests. Additionally, the module may comprise one or more indicators (lights, sounds, vibrations) for alerting a user during a fit test. The module may also detect end of service life by analyzing the sensor data, and may indicated end of service life to the user.
