Humidifier is to assist with breathing [thru mask]. Note most battery paks won't support humidifier, and for those airlines that still permit use of their power, they definitely won't permit same.
Cotton mouth occurs if one 'leaks' through mouth when sleeping - common issue for hose heads. Two often solutions is either chin strap or taping of mouth [yes - done it for several months myself, using 3M blue painter's tape, #2080]
