For a while now since we moved into a new house, our eyes have been becoming more and more dry, and our skin was itching for no reason. I have been looking at a few different humidifiers to help alleviate our problems, and came across this one. I just bought it less than a week ago, and i can already feel the difference it is making in our house. We have it placed in our bedroom, and leave the door open, so it covers a large portion of the house. Just for the fact that it was able to get rid of dry eyes and itchy skin, i would recommend this device. It has a large tank for water which last a really long time before having to refill.
