Query: I replaced it within a week..

I needed to replace three humidifers that were used for years and eventually just wore out. That model was no longer available. So I looked for a replacement.I tried this Vicks model.The unit seemed to work except when the tank became close to empty it started dumping all the remaining water on the ground.Thinking it was a fluke, I filled it up and tried again.. It seemed fine until the tank got low of water, then it again dumped the rest of the water on the floor. Not a good thing for my wood floors.I would stay away from this humidifier.
