Xiaomi Mijia Smart Humidifier 2 – 4.5Liter (MJJSQ05DY)

The Xiaomi Mijia Smart Humidifier 2 (MJJSQ05DY) is an advanced ultrasonic solution designed to transform dry indoor air into a healthy, comfortable environment. At its core is a specialized UV-C ultraviolet sterilization system that eliminates up to 99.9% of bacteria in the water before it is atomized, ensuring the mist your family breathes is pure and safe. With a large 4.5-liter tank, it provides up to 32 hours of continuous operation, making it a “set-and-forget” essential for bedrooms and offices.

This 2nd-generation smart humidifier features a 360° rotatable dual mist outlet, allowing you to direct the 350 mL/h high-volume mist exactly where it’s needed. Integration with the Mi Home App offers seamless remote control, while the intelligent Automatic Mode uses built-in sensors to maintain a constant, healthy humidity level of approximately 60%. Operating at a whisper-quiet ≤38 dB, it ensures your sleep remains undisturbed while it works to prevent dry skin and respiratory discomfort.
