I switch off and on from the full-face mask to the nose pillows, depending on how much pollen is floating around. I have my television antennae booster (with 12 VDC outlet) in my wardrobe. I run a 12 power supply across the wardrobe to my bipap machine. I put the machine on the wardrobe shelf at the left end and have plenty of hose to reach me. Plus the wardrobe is opened just enough to allow the hose to pass through and I don't hear the machine run at all. More importanly, the DW doesn't hear the machine run.
