Abstract: A helmet includes a helmet body and a gas detection and purification device. The gas detection and purification device in includes a body, a purification module, a gas-guiding unit, a gas detection module, and a power module. The gas detection module calculates the gas detection data obtained by the gas detection module so as to control the gas-guiding unit to start or stop operation based on the gas detection data. When the gas-guiding unit is in operation, the gas-guiding unit guides the gas into the body and to pass through the purification module for being filtered and purified to become a purified gas, and the gas-guiding unit discharges the purified gas out of the body to the nose portion, or the mouth portion, or both the nose portion and the mouth portion of the wearer for providing the wearer with the purified gas to breath.

Abstract: Provided is an electrically active breathing mask. The mask contains conductive layers separated by insulating layers, the conductive layers being alternatingly positively or negatively charged. Air passing through one insulating layer is directed across the surface of a next charged layer, before flowing through a next insulating layer, and so on. Particles including virus in water vapor or sputum are evaporated as they contact alternately charged layers.

Abstract: Embodiments relate generally to respirator face masks, and specifically to powered face masks which may be custom-controllable to better provide for the specific air needs of the individual user wearing the mask. For example, the face mask embodiments typically include a filter and a motorized fan, both generally located on the face mask itself, along with a processor. The processor then may use inputs, for example specific to the user and/or the environment, to control the fan speed. Thus, the fan speed of the face mask may be custom controlled to provide the appropriate amount of filtered air as the specific user needs it.

Abstract: A filter mask for filtering air inhaled and exhaled from the mouth and nostrils while providing a secure fit and comfort to the wearer is provided. The filter mask has upper and lower edges which are provided with at least one malleable stiffener for conforming to the shape of the wearer's nose and cheek area and/or the lower jaw and chin area. In some embodiments, the filter masks further comprises a malleable stiffening member configured to conform the filter material to at least a chin portion and a jaw portion of the face. In some embodiments, the malleable stiffener can have a bend portion, which allows the wearer of the mask to know which part, center and side of the mask is to be properly placed on the nose and cheek area. The masks provide excellent filtration and provide a secure and comfortable fit to the wearer.

Abstract: A personal neck-wearable device is configured to direct a curtain of protective air around the face of a wearer in use to prevent or reduce inhalation of airborne particles and pathogens. The air may be purified using filtration. In an embodiment, the air may be ionised using high voltage to ionise the air molecules with negative ions (anions) having one or more extra electrons, thereby negatively charging the air molecules. The curtain of ionised air molecules surrounds the face of the user and attracts airborne air particles by electrostatic attraction. These particles are then attracted to the nearest surface away from the mouth and nose to thereby reduce the likelihood of inhalation.
