Embodiments relate generally to methods and systems for refreshing filter media within a respirator and indicating end of service life for the filter media. A respirator may include a rollable filter media configured to be refreshed by rolling the filter media onto a roller. A rolling mechanism may rotate the roller, allowing for a fresh section of filter media to be placed in the air path of the respirator. The rolling mechanism may be controlled automatically by a motor and/or manually.
