From: Effect of aerosol particles generated by ultrasonic humidifiers on the lung in mouse
Size distribution of airborne particle released from ultrasonic humidifier with each water type. Number distribution of the size of particles from humidifier with (A) tap water, high-silica water, ultrapure, and (B) serial concentrations of calcium chloride solution are shown. The correlation of calcium chloride concentration with (C) mass concentration, (D) number concentration, and (E) peak size distribution are also shown.
