Philips DreamWear Under the nose nasal mask

Product description The special nose mask is a nasal mask that leaves the line of sight open through a frame structure that rests on a cushion under the nose instead of covering the nose completely. This nasal mask provides airflow by covering both thighs. Multiple sizes are available in various configurations to better fit a wide range of users. The frame is available in medium size. Most users will find the medium frame most suitable. The nose cushion is available in four sizes: small, wide small, medium, wide medium. The frame and cushion sizes are interchangeable so any frame of a size can be used with any cushion of a size.
