Product review (4 stars): Used to remove white dust from humidifier
In Chicago we have very hard water. No matter what I tried before to eliminate the white dust from my ultrasonic humidifier nothing worked. Using this product has REDUCED but not eliminated the dust. It is now managable but had to tweak the amount of product I use. Bottle says 2 capfuls per gallon. I have to use 5 because of the "quality" water in Chicago.
Would recommend this for ppl with hard water issues.
