Product review (5 stars): What a difference!
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.
