I have a Sunbeam Health at Home humidifier. It works okay, for a small room, but with the sort of furnace I have (think 78,000 BTU space heater) I could probably use another humidifier. I use it mostly during the winter in my office to keep the MHC humidity levels up. They hate it dry; in fact, too dry of air will cause them to die. It has a high and low setting, holds about a gallon of water, the only drawback is the heating element gets covered with hard water crud pretty quick, and keeping it clear of that crud is somewhat of a pain in the ass.
