Maintaining optimal indoor humidity is crucial for comfort and health, helping to alleviate dry skin, irritated sinuses, and even reducing the spread of airborne viruses. Xiaomi has become a leader in this space with its line of minimalist, effective, and affordable humidifiers.

But is the upgrade worth the extra cost? This comprehensive comparison will dissect every critical aspect of these two devices, from their core technology to their day-to-day usability, to provide a clear verdict on which one offers the best value for your specific needs.

Deep Dive: Design and Usability
Winner: Xiaomi Smart Humidifier 2
While both models share Xiaomi’s signature minimalist white aesthetic, the Smart Humidifier 2 wins decisively on usability. Its single most important design upgrade is the **top-fill mechanism**. You can simply lift the lid and pour water in, even while it’s running. The Mijia Humidifier requires you to lift the entire 4L tank, carry it to a sink, flip it over to fill it, and then place it back on the base—a process that is far more cumbersome and prone to spills.
The Smart Humidifier 2 also features a transparent water level indicator, allowing you to see how much water is left at a glance, a feature missing on the opaque Mijia model.
Deep Dive: Humidification Technology & Health
Winner: Xiaomi Smart Humidifier 2
This is the most critical difference between the two. Both use ultrasonic technology to create a fine mist. However, the **Smart Humidifier 2 incorporates a built-in UV-C ultraviolet lamp**. Before the water is atomized into mist, it passes through this UV-C light, which effectively kills up to 99.9% of bacteria and viruses in the water. This ensures that the mist being released into your room is purified, a massive benefit for health-conscious individuals, families with children, or anyone with allergies or respiratory sensitivities.
The standard Mijia Humidifier lacks this feature, meaning any bacteria present in the water tank will be dispersed into the air with the mist. For health and hygiene, the Smart Humidifier 2 is in a completely different league.
Deep Dive: Smart Features & Automation
Winner: Xiaomi Smart Humidifier 2
As its name implies, the Smart Humidifier 2 offers a vastly superior smart experience. Through the Mi Home app, you gain granular control that is absent in the more basic Mijia model. The true “set it and forget it” functionality comes from its **Auto Mode**, which uses a built-in sensor to maintain a preset humidity level automatically. You can also set timers, create schedules, and control it remotely with your voice via Google Assistant and Amazon Alexa—all features the standard Mijia model lacks.
