The mask may improve the comfort of the face and breathing gas, increase the temperature of air inhaled, and may suppress heat intolerant pathogenic sources outside the mask and kill or shorten the survival time of heat intolerant pathogenic sources inside the mask, thereby achieving effective protection in scenarios that are conducive to low temperature pathogenic sources. The face mask may be worn and used directly or used in conjunction with a mask when the user is wearing said mask.
