1, cold fog humidifier has the advantage of automatic adjustment with the relative humidity of the air, that is, the relative humidity of the air is low when the humidification is large, the relative humidity of the air is high, the humidification is low.
2, the disadvantage is that the humidification is low (about 1/5 of the ultrasonic humidifier), the noise is relatively large compared to the ultrasonic humidifier, but this humidifier consumes less energy, low noise.
