Use and Care of Home Humidifiers
Proper care and cleaning of ultrasonic and impeller humidifiers are important for reducing potential exposures to microorganisms, such as bacteria and molds. Microorganisms often grow in humidifiers that are equipped with tanks containing standing water. Breathing mist containing these pollutants has been implicated as causing a certain type of inflammation of the lungs. This fact sheet provides information on air pollutants associated with different types of humidifiers, recommendations for humidifier care and use, and resources for further information.
