摘要： 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.

摘要： Embodiments relate generally to systems and methods for absorbing moisture within a face mask worn by a user. A face mask may comprise at least one layer of filtration material. configured to filter one or more harmful substances from the air breathed by a user; at least one layer of absorbent material configured to absorb moisture exhaled by the user, wherein the at least one layer of absorbent material spans the entire inner surface area of the mask; at least one layer of waterproof material located between the at least one layer of filtration material and the at least one layer of absorbent material configured to prevent moisture from the absorbent material from contacting the filtration material; and at least one layer of anti-bacterial material located adjacent to the at least one layer of absorbent material and forming the inner surface of the mask.
