Many things depend on the mode of use of the device. If someone does not use a humidifier - the DS2 is larger and probably works louder (my friend has the DS2 and claims that it works louder than the DS1). The other friend doesn't notice the difference. I like my System One and would not like to rep...

Request help fitting Dreamwear nasal mask. I have been using this mask recently. The problem is with leaks at levels 14-20 (pressure 8 in CPAP mode, System One unit). I've tried different nasal cushions, but the problem remains. I will be grateful for any advice. What could be wrong?

Should I replace System One unit with Dreamstation 2, or should I replace the foam? Reviews on the DS2 are generally critical. I do not use a humidifier; my device works in CPAP mode.

I will call to service tomorrow, but I want to know something about it from other users. The unit had 2-years warranty, and I used it everyday over 3 years. The 3-year lifetime is minimum requirement for DME.

Hi,
I have REMStar Pro C-flex+ and use it over 3 years. Today, machine starts generate high pitch tone (something like a high-speed rotary turbine sound). Did you resolve your problem?
