A filtering and humidifying face mask is disclosed. The face mask includes a base mask and an outer mask removably secured to the base mask. The outer mask selectively retains at least one filtering layer and at least one humidifying layer. In this regard, upon donning the face mask, a wearer can remove and replace at least one of the filtering layer(s) and the humidifying layer(s) without altering a position of the base mask.
