Xiaomi Mijia Air Humidifier 4L (MJJSQ02LX)

Concentric Spray

The Xiaomi Mijia Air Humidifier 4L ultrasonic humidifier is a balanced solution for combating dry indoor air. The model is equipped with mechanical control, does not have a built-in hygrostat, and also does not have redundant functions that you have to overpay for. Thanks to this, the device is offered at an attractive price. All plastic elements of the device contain silver ions, which contribute to effective protection against harmful bacteria. A removable cylindrical water tank with a capacity of 4 liters is filled from above through a large neck with a diameter of 14 cm. The ultrasonic membrane oscillates at a high frequency of 1.7 MHz, breaking the water column into microparticles invisible to the eye. A circular gap remains between the tank and the closed lid, through which cold steam enters the room, and the built-in partition traps the largest water particles.

Low power consumption

At the bottom of the base of the device has ventilation holes for good air intake and cooling of internal components. And on the facade there is a rotary knob for the intensity of humidification and an LED indicator. At maximum performance, the device consumes 280 mL of water per hour, which is enough for 14 hours of continuous operation. At the same time, the device consumes only 18 watts of power, which is very little for such productivity. The humidifier will automatically turn off when the tank is removed and stop working if the water level is insufficient (the indicator lamp lights up). The advantages of the device are simplicity, reliability and economy in operation, as well as ease of maintenance. But, nevertheless, it was not without drawbacks: the maximum background noise of 38 dB is quite high for a device on “ultrasound”.
