You can find plans using google.....but its basically just a tub of water, a small frame that you make out of a coat hanger or two, and a dish towel hanging down into the water. The idea is that the dish towel wicks the water upward where it naturally evaporates. Also, a small fan blowing across the towel helps. Turn down your exhaust fan.....Do tell haha I ordered one be but a bit before I get it
