Product review (1 stars): Very disappointed.
These are too thin to stand on their own in the humidifier, and fall over on themselves.  In addition, the product is too thin - 1/4 of the thickness of the wick that came with the humidifier itself. Because of the thinness, the humidifier runs much less efficiently, and even at full speed, highest setting of humidity level, the house humidity cannot get above 30%. With the original wick, humidity level was about 55%. Very disappointed.
