This handles the white dust issue!!!
By Tall Guy
I did a lot of searching for a product that would help curtail the white dust that is created by a humidifier. This does what it says it will, am very happy with the results. Our water is medium hard and this works great. We run the ultra sonic humidifier every night so is important to have this product which is made for the ultra sonic machines. Only a cap full per tank. I ordered 3 bottles of this, it was shipped VERY fast! I will reorder when I need more.

What a difference!
By K. J. Maltz
I bought a Sunbeam ultrasonic humidifier that works well except that it requires water treatment tablets in order to prevent scaling and a white film being intoduced into the room. The problem was that the tablets are almost impossible to find in stores or online. I bought this product, put two capfulls into the water tank and now there is no more scaling and no more white film on my furniture. Compared to the tablets its also a lot cheaper. No complaints on this one.

no deposit buildup despite very hard water (will update if that changes)
By Charlie Blackwood
So far so good -- bought this to use with an ultrasonic WARM mist humidifier (slightly less common than cool mist: it boils the water before pushing the vapor into the air), in a house that has very, very hard water. In the past scale buildup and caking inside the humidifier unit has been a huge problem. But this product used as directed (2 small capfuls into every gallon of water) *seems* to be helping keep the humidifier clean. (It's only been in nonstop use for about a week this year -- but by the same waypoint last year the humidifier already needed aggressive scrubbing.) Update 2/13/14: gotten through almost a whole winter now without having to de-scale the humidifier -- amazing! upgrading to 5 stars.
