Product review (5 stars): These Really Work Against Hard Water
We have hard water in our area and as a result we have a lot of mineral build-up on just about every faucet and appliance that uses water. It is bad enough that we have pots and pans that have been ruined by the build-up of mineral deposits after a couple of boils. I was a little skeptical that these pill-shaped drop-ins for my humidifier would help much with those deposits, and so far they have worked as advertised and kept my humidifier clean.

These are simple and straightforward to use - fill the humidifier tank with water, drop one of these tabs into the water and run the humidifier as normal. It does not get much easier. It does not seem to interfere with operation or with the flow and it does not add a chemical smell to the vapor.

I use a cool-mist humidifier in my home office and I decided to try these tabs with it. After normal use it is not unusual to see a little bit of mineral deposits around the spout after a couple of days. With the tab in the humidifier I noticed that the build-up is significantly less. I also noticed that the vapor that comes out does not smell the same as before but it does not smell of chemical either - it smells somewhat cleaner and fresher, though it is not a huge difference. I noticed this because I looked for it.

According to the instructions on the packaging, these tabs contain no chemicals and the ball inside them does not dissolve. So, it must instead absorb the stuff in the water that otherwise would build up. I am very interested to see what the tab looks like when it comes out of the tank.

I am not completely sure how these tabs work, but they definitely do work and they make my humidifier run cleaner. Considering that these things are cutting down on residue and the need for constant cleaning, they are worth their asking price to me and I will be buying more.
