Product review (1 stars): Does not perform well.
In my opinion this unit does not perform as described. I have the humidifier in a 900 square foot apartment, and it will not maintain a humidity level over 20% when the heat is on. Additionally, the unit is noisy when the fan speed is on high. Replacing the wick/filter is a nuisance, as It needs to be replaced often if the unit is to function at at all. I would not recommend this humidifier or any type which employs this design.
