The Lumin is a single button device. It really could not be any easier. First wipe the inside of your sleep mask and cushion with a wipe to remove any physical residue. If cleaning your humidifier water chamber, open the chamber and place in the drawer face up. If cleaning your mask, lay your mask in the drawer face up. Close the drawer and press the button. In 5 minutes the cycle is complete and your mask and water chamber are ready for use.
