Abstract
A respirator apparatus comprises a mask with a passage and a mesh material disposed across the passage. The mesh material is fused between two layers of the mask material in a molding process. The mask is made of a cross-linked polyethylene material that is flexible, resilient, impervious to liquids, and a good insulator. The cross-linked polyethylene material may be formed to fit the individual facial contours of the wearer, and has a memory. A lip is disposed across the top of the mask, and provides a seal, preventing moist air from escaping that may fog the goggles or the glasses of the wearer.
