A power humidifier is an electronic device that is designed to increase the humidity levels indoors. However, the term "power humidifier" is not the only name given to this type of machine. There are other synonyms used to refer to it, including a whole-house humidifier, a central humidifier, or a home humidifier. These terms are often used interchangeably and mean the same thing - a device that delivers sufficient humidity to improve indoor air quality and maintain optimal humidity levels. Regardless of the name used, these humidifiers help to alleviate several health problems like dry skin, dry nasal passages, and sore throats caused by a lack of humidity in the air.
