Little lotus is a large-volume long-acting humidifier for use in homes and offices. The humidifier can simulate the form of a musical fountain; as five holes spray vapor at the same time, it gives users a new sensory experience. Unlike most other heavy fog humidifiers, the ultrasonic oscillation scheme does not require a complicated circuit control; just a USB data cable. So, it saves on the cost and allows more consumers to enjoy the product at a cheaper price.
