Cute little desk humidifier.  Powered by USB.  When plugged in, it has a cute little soft blue light.  If you fill the bottle, it will run for HOURS!  Great for use at your desk, it covers 5 square feet.  Very lightweight.  I believe it holds about 8-10 fl oz.   Comes with one filter (the one that's in it now). 

Has original box, no instructions.  Note it is NOT intended for use with aromatherapy oils.

Package says it comes with two filters.  However, I must have misplaced the extra.  So there's only one filter and it's already installed in the tube.
