A head covering air filtering device comprising a rigid component comprising a transparent face shield, a fabric component, wherein the rigid component and the fabric component combine to cover an entire head of a user and form a seal around the user's neck. The device further comprises an intake filter to filter all intake air entering the device, an exhaust filter to filter all exhaust air exiting the device, and an air mover causing intake air to enter the device and exhaust air to exit the device.

A facemask assembly includes one or more airflow vents in a lower front section of the mask as well as within the nasal area. The airflow vent allow for the outflow of exhaled heat and CO.sub.2. The airflow vents can be configured to direct inward airflow to strike an interior air filter. In some embodiments the airflow strikes the air filter at an oblique angle. The particulate capturing air filter can be replaceable. In some embodiments the air filter contains biocidal elements. In some embodiments the internal filter design enhances the capture of exhaled H.sub.2O which activates silver ions in the filter material creating a biocidal environment. In some embodiments, the facemask has two snap-in zonesone below the nose and one under the chin that can accommodate a wide variety of straps/tubing/O-ring stock and be secured behind the head via tying or various cord locks.

The present disclosure provides a self-contained breathing apparatus having a face piece vision system. In one aspect, the vision system includes a display component having an active matrix display device and a transparent heads-up display configured to be aligned with an eye of a user wearing the self-contained breathing device, and an infrared sensor component having an infrared lens assembly and an infrared image sensor for capturing an infrared image of a potential heat source that is projected to the transparent heads-up display.

Improved personal protective equipment facial wear including, in one embodiment, an at least partly adhesive mask, and one or more adhesive eye shields. In one implementation, the mask avoids significant contact with the delicate periorbital skin of the wearer, yet provides a substantially airtight seal so as to preclude moisture vapor transfer and fogging of eyeware or instruments. In another implementation, adherence of the eye shield is at least partially overlapping with the mask and creates an at least partial seal around a perimeter of the eye shield. Further, an at least partial seal is formed around a perimeter of the mask. The mask and eye shield additionally prevent nasal air flow obstruction, and address the problem of skin irritation and attachment during normal facial expression and movement of the wearer.

A respirator full face mask formed from plastic and aluminum with a multi-compound curved face seal having a superior configuration for facial fit. The present invention is also directed to provide a full face respirator as a protective device can be used in construction field, painting, asbestos handling, working in tanks, confined spaces and any type of work where a person needs to keep hazardous materials or particulates out of their respiratory system. The device of this invention includes a picatinny style clamp and rail to join together the two halves of the lens frames to the rest of the respirator.

A personal protection system including a hood configured for removable coupling to the helmet. The hood may include a shell defining a filter opening and a shield opening. The hood also including a transparent face shield disposed within the shield opening and attached to the shell and a filter section mounted over the filter opening defined by the shell. The filter section may be formed from a nonwoven filter medium material including activated charcoal particles embedded in the nonwoven filter medium material to trap smoke and odors in the air generated during normal surgical activities. the filter section may include a top surface and a bottom surface, and the activated charcoal particles may be embedded within the nonwoven filter medium material between the top surface and the bottom surface. The hood may further include a mounting element configured to removably couple the hood to the helmet.

Various embodiments of a rapid-manufacturable and cleanable face covering including a base component that retains a filter material, a cover component that encapsulates the filter material for providing an integrated face shield, and an injection-molded silicon sealant that seals the facial covering against the face. The cover component and base are each vacuum thermoformed for rapid manufacture from polyethylene terephthalate glycol (PETG) or another suitable material.

A personal protection system including a hood configured for removable coupling to the helmet. The helmet including a ventilation unit and light assembly. The ventilation unit mounted to the helmet and including a fan. The light assembly is mounted to the helmet and configured to emit a beam of light within a defined range of wavelengths that cause biological tissue and fluid to fluoresce and be visible to the user. The hood that is at least partially disposed over the helmet and includes a flexible shell and a transparent face shield. The light assembly is positioned on the helmet to emit the beam of light through the transparent face shield to a location outside of the hood and the hood is mounted to the helmet so the beam of light emitted by the light assembly is directed to pass through the transparent face shield.

The present invention relates to a personal respiratory protection device, in particular, such a device comprising a respirator body having a periphery, a filter media, forming at least part of the respirator body, and a gasket, the gasket being located at the periphery and extending along at least a portion of its length.

A head covering air filtering device containing a rigid component including a transparent face shield, a fabric component, wherein the rigid component and the fabric component combine to cover an entire head of a user and form a seal around the user's neck. The device further includes an intake filter to filter all intake air entering the device, an exhaust filter to filter all exhaust air exiting the device, and an air mover causing intake air to enter the device and exhaust air to exit the device.
