Used the hose for two nights. Lady said three days is often enough unless I just want to do it every day. Said to clean mask seal every day. Yes it does have a humidifier with it. I STILL wake up with a dry mouth. I might need her to "Tweak" it a bit higher. It has a modem of some kind that she can access from her office. But like I said I do feel more "Lively" when I wake up in the morning, dang it.
