Methods, systems and apparatus for a pouch-style mask having upper and lower mask substrates, each having a first layer comprising spunbond material and a second layer comprising meltblown material, a perimeter comprising a user contacting portion and a non-user contacting portion, and a shoulder proximate a left-side transition between the user contacting portion and the non-user contacting portion and a shoulder proximate a right-side transition between the user contacting portion and the non-user contacting portion. The mask also has a head strap assembly comprising first and second head straps each having first and second end portions, where the first end portions of the first and second head straps are attached to the left upper and lower shoulders in a side-by-side configuration and the second end portions of the first and second head straps are attached to the right upper and lower shoulders in a side-by-side configuration.

A personal protection equipment (PPE) for air purification is disclosed. The PPE includes an apparatus. The apparatus includes a filter and a scrubber unit. The filter is configured to filter the air for removing dust from the air. The scrubber unit is configured to purify the air before a user breaths the air. The scrubber unit includes a sparger through which the filtered air is pumped and bubbled in a water solution of polymer to trap remaining contaminants in the air and the contaminants free or improved quality air is sent to the user for breathing.

A personal respiratory protection device comprising a main body having a headband attachment portion, a headband attached to the headband attachment portion by a headband bond module, wherein the module includes first and second non-woven tabs adhesively bonded to opposing sides of an end of the headband, the side of the first tab opposing the headband bond side being welded to the main body.

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.

The scented filter system for a sanitary face mask is a medical device. The scented filter system for a sanitary face mask is adapted for use with a patient. The scented filter system for a sanitary face mask filters the air that flows through the nose and mouth of a patient. The scented filter system for a sanitary face mask a diffusing structure into a mask. The diffusing structure attaches to the mask. The mask filters the bulk of the air that flows through the nose and mouth of a patient. The diffusing structure: a) filters the balance of the air that flows through the nose and mouth of a patient; and, b) releases a volatile phytochemical into the air that flows through the nose and mouth of a patient.

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.
