Ultrasonic atomization naturally creates comfortable moisture. High-frequency vibrations generated by the atomization sheet's electronics break down the structure of liquid water molecules, producing mist. As the mist dissolves, a large amount of negative ions sweeps away harmful substances such as formaldehyde, sterile carbon monoxide, and bacteria. This air purifier is a small humidifier that purifies the air and prevents illness. The "Large Capacity Humidifier" has a large 4L capacity, so you don't need to change the water frequently day and night. This humidifier solves everything in the air-conditioned and dry seasons. The spray amount can be adjusted in 3 stages. The touch screen clearly displays the mist volume, timing, humidity, water shortage alerts, and operation status at a glance. The open water tank design has an extra-large diameter, making it easy to clean. Always maintain the cleanliness of the humidifier. The integrated design means the tank doesn't separate, and the seal prevents water leakage. Ultra-quiet operation with low decibels has absolutely no impact on rest or work.
