Abstract
The industrial type respirator mask uses a filter element made from a flexible sheet. This is cut to form a flat pocket of truncated cone shape (20). An opening (24) is provided at the larger end of the cone and the smaller end is sealed. This closed end is provided with fold lines (26, 27) which form a square comprising two triangular surfaces with a common base (gh, mn) perpendicular to the open ends. The lines enclosing the triangular areas common base and the open ends are stiffened by welding or application of a plastics material.
