Product review (2 stars): not as good as the original.
Arrived quickly, seemed a bit thicker than the original, but there is no structure to help it hold its shape, so as soon s it was wet, it was very floppy and hard to fit into place on the humidifier. It also circulates way less moisture. (about half of what I got before.) Also, it's starting to shed pieces and fall apart after one week of use. Would not buy again.
