Product review (1 stars): Don't Waste Your Money
This is a cheap piece of junk. I have had the humidifier for a couple of years and the "filters" purchased previously have lasted at least a couple of months. This one is less than a month old, has been treated with bacteriostat every water change, and reversed. With all the care, it is about done. If I can't find something better, the humidfier is going in the garbage.
