A mouth protection device for a respiratory protection system, in particular a blower respiratory protection system, comprises at least one mask base body which is configured to cover a mouth and/or nose region of a user and which delimits a breathing zone at least partially, and comprises at least one breathing air supply line, which is connected to the mask base body and delimits at least one breathing air channel that ends in the breathing zone and is configured for guiding an active breathing air flow,

wherein the mask base body is made at least largely of a flexurally soft material, the mask base body being made at least largely of a textile material.

A filter assembly for a breathing apparatus, such as a powered air purifying respirator. The filter assembly includes a frame for receiving and retaining a filter element, a cover connected to the frame and dimensioned to cover the aperture, a filter element, and an indicator for indicating when the filter element is retained in the filter frame and the cover is arranged across the aperture. A powered breathing apparatus including the filter assembly is also disclosed.

A mask apparatus includes a mask body, a pair of hook mounting portions at side ends of the mask body, a seal coupled to a rear surface of the mask body, and a pair of ear hook portions connected to the hook mounting portions. Each hook mounting portion includes an upper hook mounting portion, a lower hook mounting portion below the upper hook mounting portion, a hook pin at each of the upper hook mounting portion and the lower hook mounting portion, and a through-hole defined in each of the upper hook mounting portion and the lower hook mounting portion. Each ear hook portion includes a strap portion, a first hook portion connecting the strap portion to one of the upper and lower hook mounting portions, and a second hook portion connecting the strap portion to the other of the upper and lower hook mounting portions.

The invention relates to a respirator mask comprising a filter material piece made of an air-permeable material and at least one securing band, wherein the air-permeable material comprises at least one layer of a non-woven fabric and the at least one securing band is designed to secure the respirator mask to the head, wherein the air-permeable material and the at least one securing band are made of the same plastic material.

A headgear or headgear segments are manufactured to shape thereby producing little or no waste material. Such headgear or headgear segments (components) may comprise a unitary, substantially seamless structure. Techniques such as knitting, braiding, crocheting, and 3D printing may be used to produce the headgear. As a result, the manufacturing process may have reduced steps, the amount of material waste may be reduced, and there are virtually no seams in the headgear between adjoining sections, thereby resulting in headgear with enhanced comfort.

The present invention relates to a novel face mask shield device. The device is designed to fully encapsulate the eyes, nose, mouth, and ears of a user, while working in hazardous material environments. The device comprises a protective mask component, an attached headlamp, a detachable respirator filter, and detachable earmuffs with high decibel noise cancelling ability. The face mask shield device is powered by regular batteries or by a 12 v rechargeable battery. The face mask shield device keeps the user safe while working, remaining in place and offering comfortable wear for long periods of time.

A respirator for protecting against airborne particles includes a face gasket for providing a seal around the mouth and nose of a user, a frame attached to the gasket, a filter compression ring removably attached to the frame and a filter for filtering airborne particles from air. The filter is positioned between the frame and the filter compression ring. An eye protection accessory is attachable to the gasket. The respirator additionally includes a safety module that includes an air pressure sensor that can monitor the air pressure in the space bounded by the user's face and the filter. A processor analyzes the air pressure measurements obtained by the air pressure sensor and a vibration motor or a visual indicator. The processor can trigger the vibration motor and the visual indicator when the air pressure exceeds a predetermined threshold.

A mouth closure mask includes a flexible sheet having an adhesive on a back facing surface thereof, the adhesive provided for adhering the mask to the face of a wearer. A port is defined through a portion of the sheet. The port allows access between in the inside and outside of a wearer's mouth when the port is uncovered. A retaining flange is disposed on the flexible sheet adjected to the port. A seal is configured to selectively engage the retaining flange to restrict access to the port when the seal and retaining flange are engaged.

A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion extending above and behind the user's ears and a lower portion extending below and in front of the user's ears. The device includes components mounted to the frame, comprising an air intake filter mounted on the frame and communicating on one side with ambient air outside the device and on the other side with an inlet duct and an air outlet filter mounted on the frame and communicating on one side with air inside the device and on the other side with ambient air outside the device. The device also includes a battery-powered air mover mounted on the frame and operable to pull air through the air intake filter and through the inlet duct and push air out into the inside of the device and a rechargeable battery mounted on the frame to power the air mover. The device further includes a transparent face shield mounted on one side of the frame in such a way as to create an airtight seal between the face shield and the one side of the frame, a fabric component made from an air impermeable fabric and mounted on the other side of the frame in such a way as to create an airtight seal between the fabric component and the other side of the frame, and to encircle the user's neck, a head harness configured to rest on the user's head and support the frame with its components mounted thereon, and wherein the components are mounted on the upper portion the frame and on the lower portion of the frame so as to achieve a weight distribution ratio between the upper portion of the frame with components mounted thereon and the lower portion of the frame with components mounted thereon, the ratio being between 1 to 1.5 and 1.5 to 1.

This invention relates to a face mask (100, 200, 300) comprising a central area (40), comprising a fabric material (45), an elastic area (20), extending laterally at least partially from the central area (40) and comprising an elastic material (15), and being connected to the central area (40) at an interface section (30). Further, the elastic area (20) comprises an adhesive (11) provided on a bottom surface (12) of the elastic material (15) along at least a portion of a periphery of the face mask (100, 200, 300), forming an adhesive sealing profile (10). A space between the intersection section (30) and the sealing profile (10) comprising the elastic material (15) is an intermediate elastic area (25).
