Does the ultrasound in humidifiers harm childrens health in the long run?”
Ultrasonic humidifiers may be a health hazard Nutrition Health Review, Spring, 1989 BOISE: Ultrasonic humidifiers that aerosolize water pose a health hazard if tap water is used in them, since minerals and other materials dissolved in the water may be released as particles small enough to be inhaled deep into the lungs. That is the conclusion of researchers from the U.S. Environmental Protection Agency. V. Ross Highsmith and Charles E. Rodes from the agency’s Environmental Monitoring Systems Laboratory, Research Triangle Park, North Carolina, and Richard J. Hardy of Morrison-Knudsen Engineers in Boise, Idaho studied the impact on indoor air quality in Boise homes when public tap water was used with several types of humidifiers — ultrasonic, cool-mist, and steam. Humidifiers are frequently used in winter to alleviate symptoms caused by dry, heated air — such as chapped lips and irritated throats and noses. Ultrasonic units use electronic transducers to propel water into the air in fin
