@elwoodsdad @mmarsh I do not think a SoClean is a necessity, but regular cleaning is--washing mask, hose, and tank with baby shampoo or another gentle cleaner at least weekly. I'm not sure what you mean about tidying things up from time to time, but I suspect that you may develop a biofilm buildup in your equipment as I did when I have been lazy and left the same water in my tank for a week or not washed the equipment regularly. I agree that the cleaning process is a pain, and I have not always been compliant. I also agree that daily is a bit much, I only wash the nasal pillows/or mask every day due to oil buildup from my skin that makes them not stay in place and therefore leak. You do as you do, but I have serious allergies and don't want to risk getting sick from whatever might grow in there.
