Great Humidifier
I moved to the desert and tried various cheaper humidifiers but invariably they broke, and/or covered the fridge, electronics, etc in calcium dust. (Our water is VERY hard).
I've had this about a year, and it has been really great. I really like the hygrometer, which tells me the current level of humidity.
The downside? Well, it's not cheap as you can see, Also, you really need to clean it on a regular basis, like every two weeks depending on use. You can use vinegar, but they really want you to use their descaling solution (EzCal). But I think vinegar (really cheap) or coffee maker descaler would work just as well.
You also have to buy the replacement crystals, to filter out the calcium. If you don't care about the cost, you can buy them in the cylinder, otherwise you can save money by reusing the cylinder, and just getting the crystals alone. But that can be somewhat messy.
I would give it 5 stars, but I am somewhat lazy, and don't really like cleaning it. And the fact that the cost of consumables is ongoing (crystals, EzCal).
So it does require a commitment to maintenance, but if you are someone that really needs a high quality product, and you are willing to keep it running in tip top shape, you will not be disappointed.

The most excellent humidifier ever.
Awesome variety of features, and completely silent while operating. More than worth the investment for quality.
