This DreamWear Mask is suitable for mouth breathers, who can now benefit from the great features the original DreamWear brought to the market, such has having the hose connected at the top of the head rather than hanging below the mask.  Philips Respironics describe it as "like wearing nothing at all" and certainly compared to full face masks in general, it really is a light-weight mask.

• Amazed at how quiet the mask is when a good seal is achieved, even at higher pressures on non-invasive ventilators.
  
  
• A good choice for people who struggle with nasal bridge sores, as this mask goes nowhere near that area.  Also this style of mask can help people with a receding jaw as it can often be difficult getting a traditional full face mask to fit correctly both at the nose bridge area and the chin.
