No, humidifiers will not damage electronics or other home furnishings. In fact, a humidifier serves as a benefit for these items. Electronics thrive in conditions that aren’t too dry and aren’t too humid, so a humidifier that is adding a reasonable amount of moisture to the air can serve to benefit electronics in the room. Furthermore, a humidifier can be a great benefit to natural wood in the home– it can keep it moist and looking great.
