The invention discloses a respirator comprising an elastic respirator body. A cavity of the elastic respirator body is divided into an air inlet chamber and an air outlet chamber through an interlayer. An air inlet is formed in the air inlet chamber. A respirator opening matched with a human body respiration area is formed in the air outlet chamber. The interlayer is provided with a first one-way valve enabling air in the air inlet chamber to only flow toward the air outlet chamber. The air outlet chamber is further provided with a second one-way valve enabling air in the air outlet chamber to only flow toward the external world. The invention further discloses a fire mask with the same. By adopting the respirator and the fire mask with the respirator, the situation that moisture and other waste air of a human body do not go back to air inhaling space again at the time of respiring can be achieved, and the air inhaling space keeps dry all the time. 本发明公开了种口罩，包括弹性罩体，所述弹性罩体通过隔层将弹性罩体的空腔分隔成进气腔室和出气腔室，所述进气腔室设有进气口，所
