Artist’s conception of improved elastomeric respirator, with filter ports on either side of the respirator facepiece; the filters are deliberately not shown. The respirator body is transparent, and there is a speaking diaphragm to facilitate communication. The respirator would accommodate a wide variety of filters through the use of adapters, which could make the respirator more suitable to surge situations in which the supply chain for filters could be interrupted. The sealing surface is highlighted. There is no exhalation port; inhalation and exhalation take place through the same filters. Straps that hold the respirator onto the face are deliberately not shown, but are an important feature for fit and comfort. In the United States, respirators are certified for use by the National Institute for Occupational Safety and Health (Washington, D.C.); thus, the National Institute for Occupational Safety and Health would need to be involved in improved elastomeric respirator design.
