Combined Humidifier and Air Filter

I bought this at a recycle shop thinking that it was a "dehumidifier". I soon found out it that it is just the opposite of what I thought it was. I then noticed that my Japanese co-workers have something similar all over the place. In fact, many people who don't have allergies, end up having allergies in Japan because there are so many trees and plants blooming all the time. This one happens to have a Turbo setting and a House Guest setting...made the dry periods so comfortable in the bedroom. Works simply by filling up the tub of water, and it then automatically adds moisture to the air. They range from around $75 if you buy them from a recycle shop (over the next couple weeks, I'll be listing the recycle shops and Daiso's).
