Title: Expensive filter and no control
Review: Filter is made of the paper and you have to change often, otherwise it melts down. It is a $6.99 each. Even if you buy a cheap machine, it would turn into expensive machine. If you don't change the filter, this machine mists stinky water. I use a filtered water however, I can smell it. Also, I noticed that...When there is no water, it doesn't stop automatically. It will work forever when you don't stop. For example, the fan inside rotated more than 24 hours without water. I didn't know that. After that, I often check if there is water inside or not. I still have 3 more filters. After I use them, I will trash it. I will not buy it again.
