I am selling a mask used for treating sleep apnea. This type covers both the nose and mouth, making it ideal for those who tend to open their mouths during sleep. The cheek area has a hook design for easy removal and attachment. Please consider purchasing. The condition is very good, and you can use it immediately upon arrival. This is a used item, so please check the photos before purchasing. #PHILIPS #RESMED #SleepApneaSyndrome #Apnea #Snoring #Fisher&Paykel #fisher&pykel #CPAP I am selling a mask used for treating sleep apnea.
