Product review (1 stars): Filter stops working after a few days
This filter was worse than the original Honeywell filter that came with my humidifier.  It worked okay for a few days, but then it became waterlogged and lost its shape, so that it retained water instead of releasing it into the air through the humidifier.  The filter would not even dry out completely after leaving it out for two days.  I was hoping that this would be better than the original filter, but this is not it, and I'm still looking around for a better replacement for the Honeywell filter.
