Title: Noisy, dirty
Review: I bought this humidifier a couple of years ago. For the first season, it worked pretty well. Increasingly, however, it has become noisier and noisier. One possible reason is the design: by drawing air through the fan blades, it accumulates dirt and dust in the fan mechanism, which can't be cleaned. Replacing filters is a regular expense - figure out the total cost of ownership before you buy. You may be surprised.
