the contents of these is calcium chloride, the same ingredient as ice melt. Has anyone bought ice melt to refill the dri z air? I just bought 60 oz dri z air refill at walmart for $7, but you can buy 50lbs of ice melt at lowes for $30, I think it was. I am not a big fan of dri z air but may be better than nothing and I can't run an electric dehumidifier 24x7.
