 US11027157B2: Face covering apparatus and method of using the same

Abstract: A face covering apparatus and method of using the apparatus. A frame is configured to be placed in an operative position on a wearer's head and releasably maintained in the operative position by at least one of: a) resting upon one or both of a wearer's ears and b) frictionally engaging a part of the wearer's head. A covering assembly on the frame has a wall structure with: i) a first region configured to conform to the wearer's face region around the wearer's nose; and ii) a second region configured to conform to the wearer's face region around the wearer's mouth. The face covering apparatus is configured so that with the frame in the operative position on the wearer's head and the wall structure in a blocking position on the frame, the first and second regions on the wall structure together reside in the path of airborne particles moving: A) in a forward direction from the wearer's nostrils and/or mouth; and B) in a rearward direction towards the wearer's nostrils and/or mouth.
