Do you have Glasses?
Some clients like to be able to wear their glasses while wearing their PAP mask as they are preparing for bed. If this is the case a mask that does not have a stability bar would be a good option. Such as Nasal Pillows, or Nasal Cradle (N20, Wisp, DreamWisp, N30, P30, P10, Dreamwear Nasal, Evora, Brevida) If you are a month breather you may need a full face mask which fits under your nose and around your month. (DreamWear Full Face, F30)
