In some embodiments, the technologies include a sanitization gas system and a connector unit or a hole in the reservoir wall, configured to connect a supply line to the reservoir. The connector unit may include an inlet passageway for supplying sanitizing gas (e.g., ozone) into the reservoir. ## Claims ### Claim 1 A system for sanitizing comprising: a reservoir configured to be coupled to a continuous positive airway pressure device; a gas supply system configured to supply a sanitizing gas; a cover to extend across an opening on a top surface above a water level of the reservoir of the continuous positive airway pressure device, the cover comprising a connector unit comprising an inlet passageway, the inlet passageway comprising a proximal end and a distal end, wherein the connector unit spans a thickness of a portion of the said cover such that when the cover is installed in the reservoir, the inlet passageway extends substantially vertically, the proximal end is located on an outward facing side of said cover above the water level within the reservoir, and the distal end of the inlet passageway faces an interior of the reservoir; a first supply line configured to be fluidly coupled to the gas supply system and fluidly coupled to the proximal end of the inlet passageway. ### Claim 2 (depends on 1) The system of claim 1, further comprising a second supply line configured to be fluidly coupled to the distal end of the inlet passageway. ### Claim 3 (depends on 1) The system of claim 1, further comprising an exhaust system configured to remove the sanitizing gas. ### Claim 4 (depends on 3) The system of claim 3, wherein the exhaust system comprises a removable activated carbon filter. ### Claim 5 (depends on 2) The system of claim 2, further comprising a check valve coupled to the second supply line. ### Claim 6 (depends on 1) The system of claim 1, wherein the sanitizing gas is ozone gas. ### Claim 7 (depends on 1) The system of claim 1, wherein the connector unit is pre-formed in the cover. ### Claim 8 (depends on 2) The system of claim 2, wherein the connector unit is pre-formed in the cover. ### Claim 9 A system for sanitizing comprising: a reservoir configured to be coupled to a continuous positive airway pressure device; a cover to extend across an opening on a top surface above a water level of the reservoir of the continuous positive airway pressure device, the cover comprising a connector unit comprising an inlet passageway comprising a proximal end and a distal end; wherein; the inlet passageway spans a thickness of the cover, such that when the cover is installed across the opening of the reservoir, the inlet passageway extends substantially vertically and the proximal end of inlet passageway is located on an outward facing side of said cover above the water level within the reservoir and the distal end of the inlet passageway is located on an inward facing side of said cover; and the proximal end of the inlet passageway is configured to fluidly couple to a first supply line to receive a flow of sanitizing gas. ### Claim 10 (depends on 9) The system of claim 9, wherein the distal end of the inlet passageway is configured to fluidly couple to a second supply line to convey sanitizing gas to within said reservoir. ### Claim 11 (depends on 9) The system of claim 9, wherein the connector unit is pre-formed in said cover. ### Claim 12 A continuous positive airway pressure (CPAP) sanitizing system comprising: a continuous positive airway pressure (CPAP) reservoir configured to be coupled to a continuous positive airway pressure (CPAP) device; a top cover configured to be coupled to an opening of the CPAP reservoir above a liquid level, the top cover including a connector unit with an inlet passageway having a proximal end and a distal end, wherein the proximal end is configured to be fluidly coupled with a supply line to supply a sanitizing gas to the CPAP reservoir and the distal end is configured to be above the liquid level of the CPAP reservoir. ### Claim 13 A continuous positive airway pressure (CPAP) sanitizing system comprising: a continuous positive airway pressure (CPAP) reservoir configured to be coupled to a continuous positive airway pressure (CPAP) device; a top cover configured to be coupled to an opening of the CPAP reservoir above a liquid level, the top cover comprising a connector unit including an inlet passageway having a proximal end and a distal end; wherein when the top cover is coupled to the CPAP reservoir, the distal end is within the CPAP reservoir above the liquid level of the CPAP reservoir and the proximal end is configured to fluidly couple to a supply line to receive a flow of sanitizing gas.
