Got this teeny humidifier last night at Target. It works with just about any standard size water bottle, it says. They haven't turned the heat on yet at work, but when they do it sucks all the water out of the air -- last winter at times I resorted to soaking paper towels and draping them over a chair in front of my small fan (which worked remarkably well, actually. The towels dries out too quickly; needed fabric towels).
P.S. Also, according to a typo in the instructions, I am to avoid the machine spaying any nearby objects.
