We recently purchased a humidifier and we got two of these to check its effectiveness. At first we were shocked to see that the humidity in our bedroom was only around 32% - too dry! No wonder we were getting dry itchy skin. Now we use these to keep it at 45% which is supposedly ideal. Nice product. Note: when they came, one of them didn't work but the company replaced it immediately so no complaint.
