Product review (2 stars): Poor Quality
I would not recommend this product as a replacement for your filter.  Not even close to the same quality filter as the one that came in the original box with the humidifier.  As soon as these get wet they shrivel up to half the size and are flimsy and won't stay upright.  I've only used one for a few days and it's already falling apart.  My advice.....do not buy!  They look nothing like the ones that are pictured.
