hmmm....I would think most people go through insurance coverage to purchase equipment.
I tend to think that prying the humidifier tank lid up while it is inserted into the machine would cause problems not solve them.
I guess I am lucky. I have not had a problem in over six months of use.
Sleep is worth the effort.
Have been using ResMed Autosense 10 for about 2 months. Noise is driving me crazy. It's not real loud, just annoying and one more thing besides the foreign headgear, air flapping the curtains, and getting tangled in the hose that keeps me awake. My sounds are inconsistent--sometimes I hear the echo, other times a dripping sound, other times a steady humm. No voices yet, but I wouldn't be surprized. I've gotton up more than once to check for a running toilet.
