This replacement Frame Assembly for Mirage Micro Nasal Mask (No Cushion or Headgear) is available in sizes small or standard. This is the frame only for the ResMed Mirage Micro mask. You can build a complete mask by adding a cushion and headgear to this frame.
The ResMed Mirage Micro has two frame sizes (Small & Standard) and six cushion sizes (Kids, Small, Medium, Large, Large Wide, X-Large). Not all cushions fit all frames.
The part was exactly what I needed. Service was quick too.
