Ooo! Thanks for the recommendation Christine! I have needed a humidifier for YEARS. The past few weeks I have started getting nosebleeds because it's so dry in here.

But the last humidifier I had was so large & clunky. It had a water tank about the size of a small aquarium. It was too heavy to lug back & forth to the sink. I accidentally banged one corner on the sink. It got a hole in it that I had to plug up with putty or something. It was designed in such a way that it had to be flipped over to fill. So I could not simply bring pitchers of water to fill it. It had to be lugged to the sink. That was extremely inconvenient as it was up on a high shelf of my bookcase (out of the way) and the heavy water tank had to be hoisted up each time.
It also required a lot of cleaning. Having developed chronic fatigue over the last few years, I know that any humidifier I get now that requires too much maintenance is going to be sitting around waiting for cleaning, more than it will get used.
The worst part was that in the summer, it was so big, and living in a small apartment where every bit of storage space is crucial, it ended up sitting out unused as FURNITURE on my bookshelf.
I need something small, can sit anywhere near me, be easy to clean, and be stowed away during the months I don't use it. The unit you recommended seems to fit the bill on all points listed.
