A breathing circuit of the closed circuit type has improved means for removing water vapor to prevent condensation within the circuit. A dryer is placed in the breathing circuit, downstream of the CO absorber, for removing water vapor from the breathing gases, including that entrained in the breathing gases during passage through the CO absorber. The dryer may utilize a thermoelectric cooling element or a water vapor permeable membrane.
