It also became clear last night (for the 4th machine) that the Airsense 10 For Her has serious humidifier defects. Once again there was the great flood with water spraying (literally) into my face off and on all night. So..I will have the big fight with the seller and return the beast (again) - disappointed because I found it to be very pretty compared to the others available. I will set up the S9 again and use it until next spring and see what's available then. Wait until the bugs are worked out of the newer ones.
Anyway thanks so much everyone - I will get to the data and return in a few weeks with results and ask for help in interpreting the graphs and such. It feels good to have a plan and stop wandering around in circles.
