Ultrasonic humidifiers linked to pneumonitis.

Ultrasonic Humidifiers Linked to Pneumonitis

A report that appeared in a recent issue of the New York State Journal of Medicine (5/90), implicates the use of ultrasonic humidifiers in developing pneumonitis, an inflammation of the lungs.

The researchers involved evaluated two cases of noninfectious pneumonitis in which features of the disease developed after a home ultrasonic humidifier was used. Both individuals experienced remission when exposure to the aerosol contained in the device was discontinued.

Examining the machine, investigators found contaminated bacterial and fungal microorganisms from the well of the humidifier.

Because so many homes in the United States are exceptionally dry during the winter months, the need for introducing humidity into the atmosphere is important. Various respiratory diseases have their beginning in an overheated dry home.

A simplier form of humidification is available in devices that do not use aerosols. Caution should also be exercised with less complex mechanisms because bacteria accumulation can occur if the ducts and containers are not cleaned consistently.
