Humidifiers
Dry winter air cracks lips, irritates sinuses and dries out wooden furniture; the EPA suggests keeping indoor humidity between 30 and 50 percent.
Evaporative humidifiers leave no dust behind. Ultrasonic models are quiet, but with hard tap water they can spread a fine white mineral dust, so they are best filled with distilled water. Size the tank to how often you are willing to refill it.
