If you remove the headgear, cushion and swivel, the frame is essentially one tube. This can be cleaned the same way the short tubing on other masks or the longer CPAP tubing is cleaned. Wash with warm soapy water, it can be rinsed through the swivel connection as well. Set to dry and if there happens to be any remaining moisture in the tube before therapy is started, connecting it to the CPAP with pressure can help to remove this.
The mask may also be cleaned in the dishwasher once a week. The non-fabric parts can be washed on the top shelf of the dishwasher and air dried. Please refer to the instructions manual that came with the mask.
