Thank you for viewing. I am selling a ResMed AirMini dedicated tube & AirFit F20 full face mask, size M, & Humidx. I will also include an elbow for standard tubes. This is a set of the Airmini dedicated tube, mask, and humidification unit for the portable Airmini machine. The humidification unit has only been opened and not used. Please check the condition in the photos. As a precaution, I have wiped both ends and the outside with alcohol. Please understand that this is a used item. ★Immediate purchase is prioritized★
