Product review (1 stars): A WASTE OF MONEY, WHITE POWDER IN AIR AND ON FURNITURE CONTINUES
This humidifier tank demineralization capsule does absolutely nothing to clear up the problem of white powder in the air and on my furniture.  This product does not make my little room humidifier run cleaner.  Very disappointing.  Not able to reach the manufacturer by using the service email address on the package.  Response I received is " no such address".  I'm sorry to say this was a waste of money.
