A self-contained re-humidification mask (1) having locating means (6) to enable the mask to be supported in an operative position on a user (4) is provided. The mask has a wall (2) shaped as a moulded domed mask configured to cover the face of a user from the nose to the chin. An endless peripheral edge is shaped and configured to generally anatomically follow the contours of a face of a user to define, with the face of a user, an air pocket (24). The mask has a single inlet-outlet aperture (8) located generally opposite a position occupied in use by a mouth of a user, and at least one re-humidification assembly (9) located in the inlet-outlet aperture such that it substantially fills the aperture. The re-humidification assembly includes a coil (17) of corrugated hygroscopic paper having an axis of the coil extending in the direction of fluid flow through the inlet-outlet aperture. The re-humidification mask preferably has a wall formed from a non-woven synthetic fibre sheet that is press moulded and heat set to the domed shape thereof.
A self-contained re-humidification mask having locating means to enable the mask to be supported in an operative position on a user, the mask having a wall shaped as a moulded domed mask configured to cover the face of a user from the nose to the chin, the mask having an endless peripheral edge shaped and configured to generally anatomically follow the contours of a face of a user such that, in use, the domed shape of the mask defines, with the face of a user, an air pocket, the mask having a single inlet-outlet aperture located generally opposite a position occupied in use by a mouth of a user, and at least one re-humidification assembly located in the inlet-outlet aperture such that it substantially fills the aperture and is in open communication with the mouth and nose of the user and defines a fluid flow passage between the atmosphere and the air pocket, wherein the re-humidification assembly includes a coil of corrugated hygroscopic paper having an axis of the coil extending in the direction of fluid flow through the inlet-outlet aperture.
