1. A protection device, comprising:
a filter assembly having a proximal side for positioning near the face of a user and a distal side, the filter assembly comprising:
a filter;
a proximal layer and a distal layer, the proximal layer and the distal layer each having a plurality of perforations that allow air to pass through, the filter assembly configured to hold the filter between the proximal layer and the distal layer;
a one-way valve positioned in a center portion of the filter assembly and coupled to the proximal layer of the filter assembly, the valve configured to allow air to pass through the valve from the proximal side of the filter assembly to the distal side of the filter assembly;
a frame assembly coupled to the filter assembly and structured to attach the protection device to the head of the user, the frame assembly comprising:
a left temple arm having a proximal end coupled to the filter assembly; and
a right temple arm having a proximal end coupled to the filter assembly;
a seal positioned along a peripheral edge of the filter assembly, the filter assembly and the seal defining a first safety compartment for enclosing a user's mouth and nose;
an eye shield assembly having a proximal side and a distal side, and the eye shield assembly forming an upper portion of the protection device, the eye shield assembly comprising
an optically transparent eye shield, wherein the seal is further positioned along a peripheral edge of the eye shield, the eye shield and the seal defining a second safety compartment for enclosing the user's eyes, wherein the first safety compartment is separate from the second safety compartment when worn by the user such that air cannot flow between the first safety compartment and the second safety compartment;
a skirt coupling the eye shield to the filter assembly and positioned distal to the seal, wherein the seal is further positioned along a left peripheral edge and a right peripheral edge of the skirt, the skirt comprising a semi-rigid or rigid material, and forming a protective barrier extending between the filter assembly and the eye shield for covering a portion of the face of the user, the left temple arm and the right temple arm extending from the skirt; and
the frame assembly further comprising:
a left temple arm brace coupled to the left temple arm and extending towards a lower portion of the filter assembly and coupled to the filter assembly and
a right temple arm brace coupled to the right temple arm and extending towards the lower portion of the filter assembly and coupled to the filter assembly.
