Query: Perfect for me

I went through about 6 different filters in my two year olds life and this one has been the best. It is easy to keep sanatized since you can throw the dome and tray in the dishwasher and the humming noise helps my son sleep through the night. He even turns it on and off himself. It is easy to refill and replace the filter and the filters are inexpensive (about $6). It will leak if you move it with the dome on, quite a bit, but if you take the dome off it will be ok. I have put a towel under it on occasion from transfering it. And it won't turn off if the water is empty but I don't want it too and run this emtpy in the summer just for the noise.
