Product review (3 stars): My Honeywell Cool Humidifier come filter free concerning the water
My Honeywell Cool Humidifier come filter free concerning the water. But the mineral problem is another problem requiring these little over priced mini demineralization filters. I run my unit 24-7 and buy one of these filters every 15-17 days or so. Just be willing to bite the price of filters when you by the humidifier.
