More Information
Summary:A respiratory mask has a filter element that is optimally position relative to the inhale and exhale of a wearer's nose and mouth in relation to the size and shape of the filter allowing a direct pathway of the airflow between the wearer's nose and mouth to the filter. A non-permeable section, incorporated in the filter element, filtering structure, the sealing area or a combination thereof, is used to direct and channel the outer dispersed boundaries of the nasal and oral flow to the filter element. The optimally positioned filter coupled with channeling of the boundary flow through the filter element reduces residency time of exhaled breath in the mask.
