Query: Tried, does not work

I've had the bigger model of this ultrasonic for over a year, and we're very happy with that.I've run the product for a few nights. There is a lot of mist, however, the blower does not send mist up high enough to allow it to circulate the room. Next to my son's mattress, which sits on the floor, it gets the bed wet. I don't want to ruin furniture by trying to put it on the dresser in hopes the mist would circulate and evaporate.I can only imagine this product being good for traveling, when you might not care about ruining the hotel night stand.
