Product review (5 stars): These seriously work pretty good!!
These really work! We have some of the hardest water in the country and most everything fails at controlling mineral deposits, scale, and the white residue that eventually destroys anything that our water touches. I use these in an ultrasonic humidifier and the difference with them in the tank, compared to without them in the tank, is very noticeable. Knowing how hard our water is, I popped both capsules into the tank. The white dust problem caused by ultrasonic humidifiers was the first thing that I noticed wasn't as bad as before the capsules. There is still some white dust but it has been decreased by at least 60%-70%. The other noticeable improvement was how it handles the hard water in general, the scale, minerals, and calcium in the water itself that will kill any device that uses water this hard. What this product does is pretty cool! It looks like these minerals are basically "Clumped Together" in larger clumps that settle on the bottom of the tank and the bottom of the humidifiers water channels. By doing this, you can easily just flush out those large clumps from the tank and the inside of the humidifier without having to use stuff like Lime Away to scrub it away. Nothing is going to magically make those minerals just disappear, as they are a part of the water itself, but by doing it this way, the minerals can easily be cleaned out by just doing a really good flush job of the water tank. Plus, there is no smell of any kind from these capsules and they seem to last for 3 or 4 months at a time. All in all I highly recommend these for anyone using hard water in appliances such as humidifiers. You will not skip the need for a regular cleaning of your humidifier, but it's going to be a lot easier cleaning it if you have these awesome little capsules in the tank helping with your hard water problems!!
