ABSTRACT:
A filtering face mask10that has a mask body and a new exhalation valve14. The mask body is adapted to fit at least over the nose and mouth of a person to help define an interior gas space when the mask is worn. The exhalation valve14permits fluid communication between the interior gas space and an exterior gas space. The exhalation valve14has a valve seat20and a flap22. The valve seat20includes a resilient seal surface24and an orifice30through which exhaled air may pass to leave the interior gas space. The flap22is mounted to the valve seat20such that the flap22makes contact with the resilient seal surface24when the valve is in its closed position and such that the flap22can move away from the seal surface24in response to an exhalation to allow exhaled air to pass through the orifice30to ultimately enter the exterior gas space. A filtering face mask that utilizes an exhalation valve that has a resilient seal surface can enable the valve to open under substantially less pressure, which, in turn, may improve wearer comfort.
