Product review (5 stars): Twice the Moisture
I agree with J. Jones (March 27, 2015), this filter puts out a lot more moisture over the same time -- approximately twice as much as the original that comes with the Honeywell HCM-350; on the low fan setting.  It has a different mesh design than the Honeywell, though they appear similar on Amazon.  It fit fine.  It is softer than the original, so I placed it in the humidifier pan and soaked it there.  The runoff partially filled the pan.  For a dollar and change more, it is worth it.  I am very pleased.
