Cleaning the AirFit N30i is similar to cleaning other CPAP masks. When the elbow, headgear and cushion are removed from the frame, the AirFit N30i frame is one component that can be cleaned in a similar way as the short tube of other nasal masks or the long CPAP tubing. Wash all components with warm water and mild liquid detergent, rinse thoroughly and let air dry out of direct sunlight. For the frame sleeves, squeeze with a clean towel to remove excess water. Always refer to the AirFit N30i User Guide for full cleaning instructions.
