Humidifier Experiment

This Humidifier Experiment uses the principle of ultrasonic high-frequency oscillation to make the water in the humidifier vibrate with ultrasonic high-frequency for 2 million times per second to atomize into 1 micron to 5 micron ultrafine particles and negative oxygen ions, and then diffuses the water mist into the air to achieve uniform humidification, which can clean the air.
