Product review (2 stars): Not an official humidiwick filter and zero packaging
Two filters are not identical, not official humidi-wick filters, and do not come in a package, but merely in the brown box they were mailed in. I would guess someone got a larger filter of some kind and cut it into a rectangle that may or may not fit my humidifier. One of the filters is thicker than the other, and the thicker one is most like the original for size. They feel like they could fall apart, in fact, the thinner one is kind of separating. I am willing to try them to see if they will work, but I would not buy from this company again.
