Hi-
I just got a replacement machine and even though it's the same type of machine (Remstar Plus M Series) this one runs louder than the last one and it keeps me and my partner awake at times. It is not air leakage noise from the mask, it is definitely machine noise. As it ramps up to full pressure, it has a whistle sound and just the general noise of the machine is louder.
Are there any suggestions for making it quieter OR any ideas for a quiet machine? We are willing to get a quieter one if necessary--we both have health issues that make undisturbed sleep an absolute necessity.
Thanks for any ideas you all may have--we need to have a solution ASAP.
