Product review (4 stars): A Decent Wick
I've used these wicks for several years, with good results. When new, they can evaporate 10 gallons of water within a day or so, in my console humidifier. My water is from a rural well, and causes lime and other minerals to deposit in the wick, which reduces the effectiveness within three months. Thus I require two to get through the dry winter months. The reason I don't apply five stars to the wick is the difficulty to recycle the unit, at least the plastic casing. It is hard to disassemble.
