Product review (4 stars): Works Great
Purchased these replacements for my huidifer. They work great. I find that if I turn them over in the humidifier I tend to get longer life out of them. I have also found that they get dust buildup on them. after about a month or so, I will soak them for the day and then rinse them out good. I usually only need two to make it through the entire winter season. This product worked every bit as good as the original.
