Each mask is made up of a mask frame which holds the mask cushion and also allows headgear to be attached. The mask frame is the core of a mask. It is the main part of any nasal, nasal pillow, or full face mask. In this section you will find over 35 mask frames. Also in this section there is an option to purchase mask wraps. Mask wraps are fabric material mask wraps that cover the mask frame to reduce marks on face or reduce irritation on face caused by mask frame rubbing against the face. Not all masks offer a mask wrap option, please make sure to read the full product description to ensure proper compatibility.
