Xiaomi launches two new humidifiers with quiet operation, no visible mist & HyperOS

Xiaomi has announced the Mijia Mist-Free Humidifier 3 in two variants, targeting different room sizes with upgraded smart features and a mist-free evaporative design.

The 400mL/h version is priced at 279 yuan ($38), while the higher-capacity 600mL/h model costs 369 yuan ($51). Both models will be available through crowdfunding starting next Wednesday on Xiaomi’s Youpin platform.

Xiaomi Mijia Mist-Free Humidifier 3 Specifications

The Mijia Mist-Free Humidifier 3 uses natural evaporation technology instead of ultrasonic or steam-based misting. This approach eliminates visible mist, making it safer for use around electronics and more comfortable for people sensitive to airborne particles.

The 600mL/h version features a 5-liter silver ion-infused tank and supports room sizes between 20 and 30 square meters. It operates at a low noise level of 30.7dB(A) in sleep mode and uses a dome-style LED display to show real-time humidity levels.

The smaller 400mL/h version includes a 4-liter water tank designed for up to 18 hours of continuous use. It also features a silver ion coating to prevent bacterial growth and is suitable for smaller spaces like bedrooms and children’s rooms. It operates even more quietly, with a noise level of 29.4dB(A), and supports the same LED display and physical button controls.

Both models come with a 3D antibacterial filter that Xiaomi claims blocks over 99% of bacteria. The filters are machine washable and have a recommended lifespan of 6 to 12 months. The devices use a DC frequency-conversion motor, an enclosed water pump, and low-resistance airflow channels to maintain efficiency while keeping noise levels down.

The humidifiers connect to the Mi Home app for remote control, humidity target settings (40%–70%), and smart automation. Both support XiaoAI voice control and are integrated with Xiaomi’s HyperOS smart home ecosystem.

The humidifiers also offer water shortage alerts, a descaling mode, detachable components for easier cleaning, and automatic shutoff for safety. Xiaomi states both models have a compact footprint, with the 600mL/h version designed for larger living rooms and the 400mL/h model suited for smaller spaces.

In related news, Xiaomi recently launched the Mijia Wireless Floor Scrubber 4 with 18,000Pa suction power and a 40-minute battery life. The company has also introduced a new gadget that massages the scalp, dispenses serum, and aims to help with hairline care.
