Disclosed herein are methods and systems for face mask with replaceable filter cartridges and components. A face mask includes a mask component, a replaceable filter component, and a closure component. The replaceable filter component is bonded to and as between the closure component and the mask component when the closure component is attached to the mask component.

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.
