I'm on the second model of that humidifier. Just stopped working. It was something in the electronics. It was reasonably stable. The AC Infinity is just going to be so much better.
When I had the single pipe mobile AC, I had to add two little small GE humidifiers to keep up. Depending on how damn dry it was, I would run them at the lowest setting in order for them to last overnight. Changing that AC unit to a window unit contributed quite a bit to the stability of the lung room.
