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.
