3. Avoid loud noises. Although some humidifiers have a good atomization effect, they make a lot of noise when running, which will affect our work efficiency and quality of life. Therefore, we should try before buying, and humidification intensity to the maximum to test the size of the noise.
4. No white powder can be produced. In some inferior ultrasonic humidifiers, calcium and magnesium in the water may be broken into particles, which are dispersed directly into the air and deposited on furniture and the ground with a layer of white powder. Such humidifiers will bring secondary pollution to the air, pay attention to the manual when buying.
