Nose pillow here, new last month. I use distilled water (mostly) it cuts way down on the calcium-like deposits in the reservoir. I wipe the mask down with PPE wipes about every other day or so. It may begin to have an aroma if you don't. I rinse out the hose about every week or so. The two newest massk have the air feed at the back of the head. I feed the hose down from above & it stays out of my way when I roll side to side. I also use a chin strap to keep my yap shut & prevent the incoming air from rushing outta my mouth & making it feel like the entire forum's cycling socks got washed out in there.
