I bought this from Target and was immediately drawn to the filterless feature, which is convenient, but not worth putting up with the rumbling. It's pretty loud and if you're a light sleeper, don't even bother looking at this humidifier, you will not sleep. Although the tank is easy to clean, everything else isn't; there are a lot of little parts that you have to detach in order to clean inside the spout where the air comes out.
