Product review (2 stars): A nice quiet humidifier that I will never buy again.
It's okay if it holds together better than the one that came with the machine.  For some reason these filters lose their wicking capability if they are not soaked in water first.  So, if you let it go dry -- even just a half inch at the bottom, you have to take out the filter and re-soak it, and then put this limply wet filter that is supposed stand up vertically back in the humidifier.  REALLY hard if the seam also starts to fall apart.
