Product review (1 stars): AWFUL!
THE WORST FILTER!!!! This filter is like a piece of wet bread when it gets wet. Even with the humidifier running on low constantly with ample water, the top of the filter gets crusty and dried out. With prior filters, I need to rotate them every few days. With this one, it's at least once a day. It also can't even stand up when wet. It flops over constantly. If I didn't have to consistently turn the filter around, I wouldn't mind as much. Ugh, so disappointed I spent money on this.
