A filter assembly for filtering a flow of incoming air entering a pressurized breathing gas system includes a filter housing and a filter media. The filter media includes a filtering section and a non-filtering section. The filter housing is structured to be inserted within a pressure generating device used in the pressurized breathing gas system. The filtering section is disposed within the filter housing and is structured to filter contaminant matter from the flow of incoming air. The non-filtering section is disposed outside of the housing and is structured to be separated from the filtering section so as to not make contact with the flow of incoming air. The filtering section and the non-filtering section are structured to be visually compared to one another such that a contaminant matter saturation level of the filter media can be determined.
