VirtuCLEAN eliminates that issue and give you the simple solution of just connecting the PAP tubing to the VirtuCLEAN device, place the mask in the VirtuCLEAN bag and ozone enriched area, press the button on the device and let it run for 30 minutes. THAT'S IT!! VirtuCLEAN will automatically shut itself off once it has finished its 30-minute cycle of fully sanitizing and cleaning the equipment. In order to cleanse your humidifier chamber empty the water from the chamber first. Then connect the tubing that was connected to the mask to the humidifier chamber. In another, 30 minutes your tubing and humidifier will be cleaned. This innovative CPAP Cleaner takes care of everything for you.
