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.

Headgear for a patient interface includes at least one headgear strap and an indicator provided to the at least one headgear strap structured to indicate attainment of a desired adjustment setting of the headgear in response to headgear tension applied to the at least one headgear strap.

A method of making a filtering face piece respirator, which method includes: providing a cup shaped mold 20; providing a forming chamber 24 where the mold 20 is located and where loose fibers 22 are introduced into air in the forming chamber 24; causing the loose fibers 22 to be accumulated 10 on the mold 20 in the forming chamber 24; and bonding 12 the accumulated fibers to each other at points of fiber intersection, The inventive method thus is beneficial in that it eliminates steps in the manufacturing process. The fibers also are uniformly distributed throughout the mask body, and because the webs do not have to be cut during respirator manufacture, less web waste is generated.

An air filtering mask is disclosed which includes a rigid component and a flexible component. The rigid component and the flexible component combine to form a space over a user's mouth and nostrils, to form a seal therearound and to maintain the mask in place. The mask also includes an exhaust port with an exhaust filter and an intake port with an intake filter. The mask further includes an air mover pulling exhaust air out the exhaust port, thereby drawing intake air through the intake port.

A firefighter hood comprising a hood body configured to fit around a head of a wearer, wherein the hood body includes a face opening configured to be aligned with a face of the wearer when the hood is worn. The hood further includes a flap coupled to the hood body. The flap is movable between an extended position wherein the flap covers only part of the opening in front view, and a retracted position wherein the flap does not cover any of the opening in front view or covers less of the opening in front view compared to when the flap is in the extended position.

The filter mask with accessory belt combines a filter mask with powered exhaust fans and an accessory belt for carrying protective and/or medical equipment, as well as a power source for the exhaust fans. The filter mask includes a rigid mask body having opposed outer and inner faces and at least one exhaust vent formed therein. An inhalation port is formed through the mask body, and a filter covers the inhalation port. At least one exhaust fan is mounted on the inner face of the mask body adjacent the at least one exhaust vent. At least one head securement strap is attached to the mask body. The accessory belt includes at least one pocket. A power supply is received within the at least one pocket of the accessory belt. The power supply is in electrical communication with the at least one exhaust fan for providing power thereto.

An anti-germ breathing device is provided for a user, the device including a heating element housing an electric conduit; a one-way valve in communication with the heating element, the one-way valve having a first air filter and being structured and disposed for permitting entry of air from the atmosphere into the heating element when the user inhales through an inhale tube; a suction electric switch structured and disposed for connecting a battery with the electric conduit for heating the electric conduit when the user inhales; a cooling element housing a plurality of bulkheads; an air tube in fluid flow communication with each of the heating element and the cooling element; the plurality of bulkheads being sized and configured for evenly distributing air so that the air cools before it is inhaled by the user; and the inhale tube being in fluid flow communication with the cooling element such that the user inhales cooled

The disclosed passive facemask embodiments having a single exchange port covered by a filter are from a family of transparent facemasks that do not obstruct visibility of a person's mouth when worn. One problem with a typical, widely used, facemask is the difficulty in understanding a person speaking when they are wearing the typical facemask. Not only does the listener have to contend with the muffled speech of a person talking through a facemask, communication is made worse by covering up, or otherwise hiding the wearer's mouth and face with opaque filter material. Accordingly, some embodiments described herein present a clear/see-through filtration mask embodiment that does not visibly obstruct a person's mouth by providing a filtration system along or near the periphery of the facemask.

Improved facemask designs are disclosed herein. The improved facemask is designed to provide a sucking airflow that sucks aerosolized particles emitted from a person's mouth towards a filtration unit. By providing this sucking airflow, medical personnel can work on the user's mouth and facial area without worrying about breathing in the aerosolized particles. The facemask includes a covering portion that covers a user's nose and mouth. The facemask includes a central lumen that is configured to permit access to the user's nose and/or mouth. The facemask further includes an access port configured to enable airflow communication between the covering portion and a bilateral vacuum. Airflow is directed away from the central lumen towards the bilateral vacuum. By directing the airflow in this manner, aerosolized particles emitted from the user's mouth are removed in an effective amount to decrease expulsion of the aerosolized particles outside of the vacuum facemask.
