Air-treatment mask systems, and related methods and air-treatment masks

A wearable air-treatment mask system, comprising:

• a mask body including a face-securing member;
• at least one controllable air treatment device supported by the mask body, the at least one controllable air treatment device configured to controllably treat incoming air;
• at least one pollutant sensor configured to sense ambient air for a presence of at least one pollutant therein and further configured to output one or more signals responsive to the sensing;
• control electrical circuitry operably coupled to the at least one controllable air treatment device and the at least one pollutant sensor, the control electrical circuitry configured to control operation of the at least one controllable air treatment device responsive to receiving the one or more signals from the at least one pollutant sensor;
• and
• a data transmitter coupled to the control circuitry, the data transmitter configured to transmit information at least related to pollutant data encoded in the one or more signals to at least one of a personal computer, a portable device, a third party, or another wearable air-treatment mask.
