摘要： A light-weight face mask can heat and humidify inhaled air with previously-exhaled air by passing the air through a highly-effective and highly-efficient heat exchanger disposed within the mask. The heat exchanger has a multitude of layers of metallic mesh through which the air passes generally linearly. The warm exhaled air heats the mesh which in turn heats the incoming air before it is inhaled. Moisture from the exhaled air condenses on the relatively-cool heat exchanger and humidifies the incoming air. Inhaled air enters the mask generally upwardly, and exhaled air exits it generally downwardly.
