@johnbishop Thanks John so much. You know you hate to buy things that's just await of your money. I haven't used my Cpac machine in 2wks because today l am approved to get a new machine so they didn't want to give me new supplies when l will be getting a new machine. What is the name of your machine? I have been looking online on reviews of different machines and l saw that the Philip's has great reviews. I can only get a new one every 4yrs. I have the reamed and they have good reviews but l want the best one if possible. Glad to hear from you and you always have great advice. Thank you !!!
