I am used to the humidifiers from my childhood, where you could see a stream of warm steam coming out of the machine. This humidifier feels cold and never really feels like it's adding much moisture to the room, although from the water that disappears I know that it must. It is loud when it is operating, however it is a "white noise" type of sound. I find that unless you run this thing 24/7 the filter gets nasty very quickly. There is also no way to clean the fan and grates without practically breaking the grate of the top. Maybe this is a safety factor, but it's gross to not be able to clean the fan blades. Also, there is no way to clean the refill bucket. The spring to the container lid broke early on, but if I turned the container over quickly I could still get it to work, it just spilled a little water until it settled into it's nook. So this works, but keeping it clean is not easy to do.
