Product review (4 stars): More solid than others, still looses absorbency.
Better than the ones from Honeywell and the laughable ones from discount knockoffs.

More sturdy and framed with wire. STILL, after 3 weeks you will find yourself constantly needing to flip the filter and pour water over it whenever you are refilling the tanks. In the past I have tried to drape some absorbent fabric over the filter to prolong it's absorbency - with mixed results.

So buy this - if you already bought the humidifier. Better yet, buy another humidifier with different design entirely - wherein the manufacturer isn't trying to con you into buying new filters every week.
