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.

Personal protective equipment and methods for providing an air shield from airborne pathogens and other harmful particles are disclosed. According to an aspect, personal protective equipment for providing an air shield includes a body having a first end and a second end. The body defines an interior channel that extends between the first end and the second end. Further, the body defines an inlet opening extending from an exterior of the body to the interior channel for receipt of air into the interior channel. The body also defines one or more outlet openings that extend between the interior channel and the exterior of the body for exit of air from the interior channel. The personal protective equipment also includes an attachment mechanism attached to the body and being configured to affix the body to another object.

A powered air purifying respirator (PAPR) with an active heating system. The PAPR includes a powered air component designed to be carried by a user of the PAPR, the powered air component including a fan and a filter, wherein the fan draws air from a user's environment through the filter. The PAPR further includes an electronically controlled active heating element and a control system. The control system varies the power provided to the heating element and further disables the heating element when potential overheating of the heating element is detected. The present invention further includes a heating module for use with a PAPR. The heating module includes an electronically controlled active heating element. The heating element is disabled when the fan in the PAPR is not rotating.

A system which is composed of a blower unit for a powered air purifying respirator and an electrically powered accessory. The blower unit has a blower device and a battery for powering the blower device. And the accessory is equipped with a power connector. The blower unit provides a power outlet for connection with the power connector. The power connector has a plug. Furthermore the power connector has an unplug lever for retracting the plug for unplugging. The unplug lever and the plug are connected by a pivot joint that forms a pivot axis. The unplug lever forms a handle arm and a counter arm that extend away from the pivot joint in opposite directions.

A breathing apparatus includes a blower unit including a blower. The breathing apparatus further includes a battery pack including at least one electrochemical cell. The breathing apparatus further includes an adaptor including an adaptor housing physically connected to the blower unit and the battery pack. The adaptor further includes electrical contacts that engages with corresponding electrical terminals of the blower unit and the battery pack, such that the blower is electrically coupled to the electrochemical cell. The adaptor further includes at least one communication interface for receiving data from at least one of the blower unit and the battery pack, and transmitting data to an external device.

A disposable face mask includes an upper portion of the face mask and a lower portion of the face mask, the upper portion and lower portion of the face masks each adjoin monolithically formed therewith face mask straps defined by perforations in a web of material used to form the face mask and straps, wherein the perforations allow the straps to be partially separated and utilized for securing said face mask to a wearer's face. The disposable face mask may be made by perforating patterns into a web of materials to define the face mask straps and face mask body that are formed monolithically from the web of materials. The face masks may be wound on a roll for dispensing by tearing off from the roll and then separating the straps at the perforations. Alternatively, the face mask borders may be cut-through to allow dispensing of the face masks individually from bulk packaging, where the face mask is removed from the package and the straps are separated at the perforations to allow the face mask to be secured to the wearer's face by tying the straps behind the wearer's head.

Aspects of the invention relate to personal protection systems against COVID-19 including face masks and methods, systems or devices of managing, regulating and/or filtering airflow during travel on an aircraft, train, or bus.

The sterilization mask with UVC reflective chamber includes a chamber with reflective liner, through which inhaled and exhaled air passes. The reflective chamber is also referred to as a sterilization chamber. Using a reflective chamber ensures each photon of UVC light has a long life, thus dissipating slowly. Increasing the life of the UVC photons decreases the quantity of photons that must be created. Thus, less power is required to achieve the sterilization. Sterilization is defined as a 6-log reduction (99.9999%) of various microbes including viruses, bacteria, and spores. Heat generated by the UVC lights is carried away from the mask by a heat transfer fluid, the heat dissipated away from the user.

Masks for being worn by a person are described herein. The masks include a shell configured to cover a nose and a mouth of the person, at least a portion of the shell having sufficient transparency to provide for visual observation of the mouth of the person when the person is wearing the mask. The shell includes an inhale port configured to provide for air to pass from an environment into a cavity defined by the shell when the person wearing the mask inhales and an exhale port configured to provide for air to pass from the cavity to the environment when the person wearing the mask exhales. The masks also include a retaining element coupled to the shell for retaining the mask on the person.

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.
