Hi John, again...thank you for responding so quickly. I am not usually a complainer and this is all so out of character for me. I am a little confused as to how the humidifier works. I am glad that we have the same machine....it will help me understand. I understand the heated hose but when you refer to "the heat" are you referring to the humidifier? Can you give me a crash course on how the humidifier works? 🙂 When you refer to hose setting and heat setting can you change what you are saying to heated tube and humidifier? The terminology in throwing me a little. Thanks!
