The present invention relates to a protective face mask and filtration article, a method for using a protective face mask and filtration article, and a design for manufacturing. In particular, the invention relates to a self-contained, mobile, battery-powered bioactive and filtering breathing appliance that provides broad spectrum antimicrobial and allergic protection via an atomized biocidal agent steam/vapor and a torturous hydrophilic filtration article that sterilizes incoming air and captures debris. To this end, antimicrobial activity and filtration functions leverage a redundancy of means/methods comprised of antimicrobial hydrogen peroxide liquid/vapor/steam and an iodized salt containing hydrophilic filtration article. The present invention is a wearable apparatus that sterilizes incoming air by capturing, neutralizing and destroying airborne pathogens and other particulate matter and pumps sterilized oxygen/air for natural, unlabored breathing by the wearer. The present invention further relates to a production method thereof.

In an example, a cover device for a regulator, which has a purge button and a mouthpiece connected to the regulator, includes a body which has: a mouthpiece housing to receive the mouthpiece through an access opening which presents a friction fit to squeeze the mouthpiece passing therethrough in a squeezed state to enter and exit a hollow interior of the mouthpiece housing, the hollow interior configured to store the mouthpiece in a relaxed state; a regulator support connected to the mouthpiece housing to support a bottom surface of the regulator when the mouthpiece is inserted into the hollow interior of the mouthpiece housing; and a button cover connected to the mouthpiece housing to cover the purge button on a top surface of the regulator when the mouthpiece is inserted into the hollow interior of the mouthpiece housing, while exposing a portion of the top surface of the regulator surrounding the purge button.

A respirator mask facepiece thermoformed from a sheet of polymer material includes an opening that is covered by a filter membrane, which may be part of a detachable disposable filter cartridge. The polymer material of the facepiece may be transparent to enable a wearer's lips to be seen. The filter cartridge may include a filter membrane attached to a carrier frame, and may be attached to the facepiece via a set of threads formed on the carrier frame and the facepiece, which draw the cartridge and facepiece together to form a seal therebetween. A latch, catch, or other similar structure may be formed in the facepiece and/or carrier frame to inhibit the cartridge from being inadvertently detached from the facepiece.

A safety breathing apparatus has a sensor for measuring the difference in pressure between two point 1a, 1b in the gas delivered to a head unit 9. The sensor is used to measure the difference in the pressure of the gas supplied through the apparatus between the two points in the gas flow, and the pressure difference is then used to calculate the gas flow rate.

The present application discloses an electric breathing apparatus and an air filter device for the same. The air filter device comprises a blower unit including a housing; and an air filter unit removably connectable to the blower unit. The housing includes an interface configured to face towards the air filter unit when the blower unit and the air filter unit are connected to each other. A casing of the air filter unit includes a filter mesh side configured to face towards the blower unit when the blower unit and the air filter unit are connected to each other. The housing of the blower unit includes a first subset of Hall sensors at the interface. The first subset of Hall sensors includes N Hall sensors spaced from each other, wherein the N is an integer equal to or greater than 2. The casing of the air filter unit includes N alignment positions at the filter mesh side. When the air filter unit is connected to the housing of the blower unit, the N alignment positions are aligned with the N Hall sensors respectively. The air filter unit includes one or N magnetic counterparts selectively located at the N alignment positions. The one or N magnetic counterparts are arranged in a manner corresponding to an operating mode of the blower unit with respect to the air filter unit.
