Dry winter air can take a toll on your skin, nose and lips. To increase the humidity indoors, try a portable home humidifier. Set the humidity level between 30 and 50 percent, and fill the humidifier with distilled or demineralized water. Change the humidifier water every day if possible. Clean the humidifier every three days. If the humidifier has a filter, change it at least as often as the manufacturer recommends.
