The system comprises an ozone operating system, an ozone distribution line, and a connector unit. The ozone operating system pulls in ambient air into an air pump to create ozone. The ozone may be pumped directly into the CPAP device and/or a water reservoir tank through the ozone distribution line. The ozone released into the water reservoir disinfects and sanitizes the water reservoir, and the remaining ozone will release as free ozone, which migrates as a gas into the CPAP hose, mask and mask compartment. An exhaust port releases the remaining ozone into the atmosphere as oxygen (02).WO 2013/012696 PCT/US2012/046593 1/11 113 130 111 122 1118 115 105 110 112 116 100 124 FIG. 1
