How high does the CPAP machine need to be? I keep mine on a box about five inches high on the floor, below my bed. It would be more convenient to keep it on my bedside table which is the same height as my bed. I have no trouble with rainout or water in the mask. The tubing would make a loop downward (like a drip loop for an aquarium).
I realized recently what could happen when you turned to agressively over in bed and had your tubing tangled in your covers. Yes, you are right the whole cpap unit hit the hardwood floor. So resmed would be happy to know that their S-8 unit passed the consumer reports test for abusing your cpap unit. I am going to keep mine on the floor from now on.
