Summary:Described herein are respirators that include a layer of wrinkled media. The wrinkled media includes a first series of substantially parallel non-bonded elastic filaments between a first and a second non-woven porous web. The first non-woven porous web is directly bonded to the second non-woven porous web. At least one portion of the wrinkled media is resiliently extensible under tension. L'invention concerne des respirateurs qui comprennent une couche de milieu plissé. Le milieu plissé comprend une première série de filaments élastiques non liés sensiblement parallèles entre une première et une seconde bande poreuse non tissée. La première bande poreuse non tissée est directement liée à la seconde bande poreuse non tissée. Au moins une partie du milieu plissé est élastiquement extensible sous tension.
