Dry mucous membranes, watery eyes, skin problems, throat and respiratory issues are fundamental troubles that can result from staying in rooms where the humidity level does not exceed 30%. An ultrasonic humidifier, operating on the principle of ultrasonic waves, transforms pure water into cool and refreshing mist while generating a significant amount of negative ions that precipitate pollen, dust, and other impurities in the air. A low-energy device can emit cool or warm mist.
