A protective face mask that includes a power source, ventilation mechanisms, filtering mechanisms, audio and video mechanisms, headphones, a lighting mechanism, a night vision mechanism, a visual zooming mechanism, protective eyewear, a head canopy, a thermometer, a DNA testing mechanism, virus detection mechanisms, radio communication technology, and fiber optics technology.

Aspects of various embodiments herein may be implemented as follows. An apparatus has a material shell that conforms to a user's face, and a securing portion connected to the shell that may operate to secure a filter to the user's face with the filter covering the user's nose and mouth. A securing force may be applied to the filter via the first material portion in a direction toward the user's face, thereby sealing the filter around the user's nose and mouth. Various implementations involve elastic and other material that facilitate sealing of the filter around the user's nose and mouth.

A face mask has a centrifugal fan assembly, with a radial outlet outside the mask cavity. A flow adjusting element is added to prevent outlet flow from the fan assembly traveling along the outside of the mask and reaching the user, for example at the neck.

A device of generating inactivated viruses and killing respiratory viruses in exhaled air in real time includes a mask; a wearable assist member having two ends secured to the mask; and a filter attached to the mask, the filter including a rear exhaled air collection chamber, an intermediate member for deactivating viruses, and a front chamber for passing air with inactivated viruses all communicating with each other. The rear exhaled air collection chamber includes an inlet attached to a front portion of the mask and communicating therewith, and a space communicating with the inlet. The intermediate member for deactivating viruses includes a channel and at least one element for deactivating viruses. The front chamber for passing air with inactivated viruses includes at least one outlet on a front end and an internal fan spaced from the at least one outlet.

A reusable multipurpose face mask is provided, particularly a face mask with a transparent shell, a housing having two air passageways with chambers that are covered by replaceable, disposable, and/or reusable membrane filters coupled to two openings in the transparent shell that are positioned on the sides of the face mask, and a third multipurpose opening that can be used for a housing having a mini rechargeable voice amplifier with built in microphone and speaker. An adjustable reusable hook and loop Velcro fastener elastic strap is attached to the transparent shell and adapted to be adjusted using the hook and loop and then removed and replaced by stretching the elastic strap while removing without having to adjust the Velcro strap each time. A system is also provided comprising the face mask and a germicidal UV light sterilization box for housing and recharging the mask when not in use.

A multifunctional face mask assembly apparatus to help to prevent or reduce heat-related illness for individuals working in high temperature environments. Fastened to the face, head and neck, to provide a cool ambient microclimate and/or aid in lowering skin temperature around the face, head and neck to aid in cooling the regulation of cerebral blood flow by means of the Hypothalamus which is responsible for regulating body temperature. The multifunctional face mask assembly use ice cooling technology to help lower temperatures when experiencing hot flashes, aid in reducing the onset of a fever, aid in improving performance by means of pre-cooling, intermittent cooling, per/mid-cooling or post-cooling during exertional sports, fitness and/or exercises, use in Cooling Centers to lower temperature around the face, head and neck. The apparatus is optionally housed, secured or attached within the nose cup cavity opening of an elastomeric half facepiece reusable respirator, full facepiece respirator, resistance training mask, dust particle mask or face mask. The apparatus is optionally use to housed, secured or attached to handheld/portable Nebulizer mask, elastomeric half facepiece reusable respirator, resistance training mask, dust particle mask or face mask nose cup. The apparatus is fashioned, designed, shaped or configured for use as a Helmet Face Covering for (e.g., professional, college, schools, recreation, entertainment, leisure or, outdoor recreational activities).

This application discloses a novel face mask with a neck hanger that facilitates flow of filtered fresh air inside the face mask for inhaling. The neck hanger is a lightweight tube that houses two fans, HEPA or ULPA filters, and a battery with a controller circuit. One fan sucks the air from the environment and after being filtered is blown into the face mask through an air pipe that is attached to both the neck hanger and the face mask. The exhaled air from the nose or mouth is sucked by a second fan through another air pipe, then filtered and released into the environment.

A sensing element includes a substrate including an electrically non-conductive surface, at least one high surface energy region, and an electrode pair structure disposed on the electrically non-conductive surface. The electrode pair structure includes at least one pair of electrodes having a gap therebetween. At least one of the electrodes is at least partially within the at least one high surface energy region. The sensing element is configured to sense fluid-soluble particulate matter.

Provided is a mask fitting level determination device that has a significantly simple component configuration, that can be driven by a battery, that can be reduced in size to a palm size, that is inexpensive, that is operated by a simple operation method, and that does not require proficiency for accurate measurement. The mask fitting level determination device includes: a mask inner pressure detection unit 2 that is inserted between a face surface F of a mask wearing person and a worn mask 1; and a circuit control unit that sets a predefined threshold value in accordance with strength of breathing of the mask wearing person and determines a fitting level on the basis of a reference pressure value and a mask inner pressure value measure by the mask inner pressure detection unit 2; and a display unit 3 that displays the fitting level determined by the circuit control unit to the mask wearing person.

A rapidly deployable, pressure sealed, cough and sneeze aerosol, containment apparatus and a system to virtually eradicate the cold, the flu, and Covid-19. A face mask having a rigid first section configured to hold a filter and a pliable second section configured to fit on a person's face; a face mask seal formed on an edge of the pliable second section of the face mask; a curved surface on the face mask seal configured to fold inward to form a seal on the person's face when pressed on the person's face.
