Hello..I am asking a question for a friend of mine that has a horriable case of Sleep Apnea. He has had his machine and full face mask for the longest time. I am sure it is not under warranty. Well, the thing is a P.O.S now, and it really is not helping him at all. He no longer has insurance. I am very concerned for his health. Does anyone know where you can get these machines at a discounted rate? Thanks in advance.
