Query: Works Fine For Me

We bought this humidifier about 3 months ago because our bedroom was becoming so dry that we were waking with dry throats, bloody noses, and so on. This machine has solved that problem and we have encountered no significant difficulties with it. It is not too difficult to maintain, and the only problem in that area is locating filters in local stores, although Amazon and other online retailers carry them. (I do wonder why the tank always leaks water at exactly the moment I move it over the machine, but not before; I can't figure it out but there must be a reason why this happens). Re: Mold. Apparently the person who complained of mold didn't realize the filters should be changed regularly, frequency depending upon the quality of your water supply.
