This invention is a smart face mask with a transparent portion which covers a person's mouth, at least one impellor-driven air filter, and at least one passive air filter, wherein the air filters are in fluid communication with the space between the transparent portion and the person's mouth. Air can be drawn into the mask through the impellor-driven air filter primarily by the impellor, but air flows into or out of the mask through the passive air filter due to the person's respiration.

The invention relates to a respiratory air purifier device. In order to provide an improved respiratory air purifier device which is able effectively to retain viruses, a respiratory air purifier device 101 is proposed for retention of viruses from respiratory air flowing through the device 101, the latter having an interface 110 designed such that it can be placed by a wearer sealingly onto at least one respiratory opening, a hollow-fibre dialyser 120 as a filter, and a connection piece 130 between the interface 110 and the dialyser 120, wherein interface 110, dialyser 120 and connection piece 130 are configured in such a way as to form an airtight fluid channel which fluidically connects the interface to either only the exterior of the hollow fibres X or only the interior of the hollow fibres I of the hollow-fibre dialyser 120, and wherein the purifier device 101 is designed in such a way that, in at least one flow direction E, A, each flow path pE, pA that runs completely through the purifier device extends through the pores of the hollow-fibre membranes, i.e. transversely with respect to the hollow-fibre membrane, of the hollow-fibre dialyser 120.

An embodiment of a positive pressure loose-fitting head device, such as a hood, helmet or headgear, with exhaustion conduit directing exhaust into user's PPE is shown; there may be an outflow/exhaust drain; there may be a outflow/exhaust tube/conduit under shroud into PPE; there may be connections for add-ons (controls, dampers, valves, diffusers, filters . . . ); there may be an outer shroud and an inner shroud; there may be purified air from power unit; there may be an inflow location.

A face mask that uses a super sticky substance that is sprayed between the 3 material layers of the mask and in its exhaust valve filter to trap and hold particles or microbes when breathing in and out and replicates the body's own sinus defenses in filtering air via cilia hairs and sticky mucus.

The present invention provides a wireless rechargeable and portable anti-microbial respirator. The respirator includes a face-piece with an air inlet and an air outlet; a first belt and a second belt, the first belt is connected to ends of the face-piece, and the second belt is configured to wrap around the waist of a user; a flexible outlet tube, where the first end of the flexible outlet tube is connected to the air outlet of the face-piece; a flexible intake tube, where the first end of the flexible intake tube is connected to the air inlet of the face-piece; and a filtration system fixed onto the second belt. The key features of the respirator in the present invention include highly antibacterial and antiviral, long duration, reusable, self-cleaning and self-disinfecting, lightweight and portable, wireless power transfer, and great airflow and comfortable breathing.

In some embodiments, a facemask assembly can include a strap system, a facial skirt, a filter assembly, a filter material, mounting bracket, front section, a tilt mechanism, and/or a seal-tester. In some embodiments, the facial skirt has at least two seal-layers. In some embodiments, the strap system has a crown section.

An eyeglasses-like frame may include a central section that horizontally traverses a wearer's face. The central section may include a first cheek portion sized and configured to be disposed at least proximate a cheek of the wearer, and a second cheek portion sized and configured to be disposed at least proximate a cheek of the wearer. A bridge portion may be generally horizontally disposed between the first cheek portion and the second cheek portion. The first cheek portion, the second cheek portion, and the bridge portion may be disposed below a lower portion of the wearer's eyes. The eyeglasses-like frame may include a left temple section connected to the central section via a first hinge and a right temple section connected to the central section by a second hinge. A mask may be connected to the frame and the mask may be adjustable to tighten around the wearer's face.

A face mask is provided. The mask comprises a body defining an interior side and an exterior side of the face mask; a one-way inlet valve that only allows gas to pass from the exterior side of the body to the interior side; and a one-way outlet valve that only allows gas to pass from the interior side of the body to the exterior side. By providing a face mask configured in this manner, the mask is able to provide fresh air to the wearer while reducing the likelihood of contamination by pathogens or other toxic matter.

A face mask system for removal of pathogens from exhaled air comprising at least one flexible layer comprising a first surface and a second surface, said second surface being opposite to the first surface, and the first surface being in sealingly contact with the face of a user and the second surface being exposed to the environment, wherein at least one layer is provided with an exit port and an inlet port and further wherein the exit port is sealingly connected to a deformable outflow chamber and said exit port further comprising a one way exit valve that is configured to open when a user exhales air and which exit valve closes when the user inhales air.

A breathing mask comprising a mask body, a mask bead, a strap holder and a filter device. Mask bead, strap holder and filter device are connected to the mask body and/or are part of the mask body. The breathing mask encloses the nose and mouth of the user, the mask bead partially delimiting a receiving opening for the nose and mouth. The filter device comprises at least one filter receptacle and at least one filter element. The mask bead has a bearing region configured as a sealing lip and is designed such that the breathing mask bears with the sealing lip on the facial skin around nose and mouth and provides a substantially leak-tight seal to respiratory gas. The filter device is at least in part exchangeable and respiratory gas can at least partially flow through it.
