If you are on a well and septic or non-chlorinated water supply, it is important to first boil the water and then let it cool, or use distilled water to clean your CPAP equipment to minimize introducing other germs into the machine.
It is important to note that while there are many machines that claim to clean CPAP machines, to date none of them have obtained FDA clearance or approval to clean this equipment.
There are two main types of machines used to clean CPAP machines, those using ozone gas and others using ultraviolet light.
The FDA also has not yet received data or evidence for manufacturers that say UV light can clean the inside surface of CPAP hoses or information to confirm that the UV light does not damage CPAP machines.
Despite not having FDA clearance or approval, devices used to clean CPAP equipment are gaining in popularity in part because of accepted use of ozone in the food industry, hotels for sterilization, and for water purification.
