Can I position the VirtuCLEAN below the CPAP, or will the VirtuCLEAN have to be on the same level as the CPAP?VirtuCLEAN should be on the same level with the CPAP. This allows the ozone to flow easier. If the space you have requires you to put the Virtu CLEAN on the shelf below your CPAP, please periodically check the valve assembly to make sure that no liquid has gathered in any of the tubings as this could damage your VirtuClean.
