Objectives: The aims of this study was to investigate the concentration, particle size characteristics and components of airborne particles dispersed in air by using tap water, water purifier, and distilled water for the ultrasonic humidifier.
Methods: The number concentration and size of particulate matter were measured by a real time monitor, and the mass concentration was measured by gravimetric method at 1m from the humidifier. The influence of moisture during the measurement was eliminated using a thermal desorber. The metal components were analyzed using ICP-MS.
Results: Particulate matter generated in the air was significantly different depending on the water used in the ultrasonic humidifier. Both number and mass concentration of particles were in the order of tap water＞ water purifier＞ distilled water. The concentrations of heavy metals were in the order of tap water＞ water purifier＞distilled water, and the concentration in the air tended to be the same overall. But it was difficult to judge whether the heavy metals generated in the air could have a health effect.
Conclusion: The use of tap water for ultrasonic humidifiers may not be desirable from the risk management point of view, even though the health risk is clearly not known.
