I love the quiet level of this humidifier. It does have a light humm, not like a table top fountain, and a little light gurgle but nothing that is obnoxious or would keep me awake. I prefer warm mist humidifiers because they are recomended for Asthma sufferers and for kids who get the croup alot. There is a variable humidity dial and I'll keep it low for night and high for when I'm sick. Low will last 2 days and high moisture lasts about 10 hours. I'm not thrilled about the little mineral pads but they do collect ALOT and I have Chicago city water. I will soak the base twice a year in vinegar and it cleans up beautifully! No need to heat the vinegar, besides it would end up as a vapor and stink up the room. The filling of the tank is on the bottom and can be a little cumbersom getting the seal just right and then flipping the tank over to return it to the base. But over all, I'm very happy with my humidifier and I've had it for 3 years now and I don't plan on replacing it any time soon.
