Product review (1 stars): Leaves a potent smell.
Item is as described, but it smells awful!! The directions state to pour a cap full of the solution into 2 gallons of water.  My humidifier tank is only 1 gallon, so I poured half a cap full.
As soon as I turned the machine on, I could immediately smell the solution.  It quickly filled the room and did not go away for about 45 minutes after I shut it off.
I dumped the water out, rinsed the filter, and put new, fresh water in the tank. Smell is nonexistent.
