Humidifier makes 2 July 3, 2013
Reviewer: Karen Jambura from Boise, ID United States  
I love having 2 full machines. I can just take my tubing and mask between bed and the TV room!

Great machine, but one word of caution March 9, 2010
Reviewer: Karen from Colorado  
I love this machine very much, but it should be noted that you cannot fill the humidifier to the fill line or you run the risk of getting water in the CPAP machine itself. I killed two machines this way before we figured it out. We had to call the manufacturer to find out what we were doing wrong.  I fill it 1/2 the way up now and it lasts all night on setting 3.
