Product review (1 stars): I am disappointed.  They don't wick water very well.
Bought these directly from Sunbeam to use with a Honeywell 6009 humidifier.  These are terrible.  They fit exactly, but they don't wick water.  They stay two-thirds dry, rendering them ineffective.  I flip them too to bottom to get water at the top and alle the dry part to soak, but it's just no use.
