You did not mention which version of the cms-50 that you own?

Thanks to all who have replied I have changed the level a few times but have not moved it down i will try it tonight. I do have a heated hose. but only the nasal pillows to use.

I have an S9 auto set with the Hi5 Humidifier. The problem that i am having is my nose keeps drying out real bad to the point that it gets hard to breathe. I have the humidity level at 5.5 and the water temp set to 70. Any help would be greatly appreciated. Thanks in advance.
