Opening the dishwasher when using the heat dry setting and letting the steam into the house works great to get moisture in the air. It will be wasted steam so may as well use it. We use wood heat and I keep a big kettle of water on top of the fireplace insert. I use Static Guard spray in the car and I spray my shoes, coat, gloves, hats, scarves, and most important of all my hairbursh with the stuff.
