I'm a big fan of the Cool Mist Humidifier. It's actually the 2nd one of these I've purchased. Their compact shape is perfect for apartment living. I have tried a number of humidifiers, and this is by far the easiest one to clean and maintain in good condition. My only qualm is that the humidifier often leaves some dampness on the floor in the mornings after running all night (I need to try elevating it, to see if that helps)
