Product review (5 stars): Super cheap price, exact same wick filter.
First, there is no branded packaging of any sort. If that bothers you, look elsewhere. Second, it basically looks like any other wick filter, but cut to the specific size stated. It actually looks like I bought a big sheet of filter and cut it myself. That also does not bother me because I cut it again to fit my humidifier, which is different than the ones listed. This is about half the price of the normal branded filters and it is the same material and I get twice as many uses. So for me, it's 1/4 the cost.
