Abstract
A device includes a cartridge containing a filter material. An insert extends through at least a portion of the filter material. The insert has gas sample path with an opening to provide a sample of air that is representative of the saturation of the filter material. A return path may be included in the insert to return sampled gas to the filter material. A gas mask contains a gas sensor and coupled to the cartridge, which may be replaced when saturated.
