Xiaomi has officially expanded its smart home lineup with the launch of the Mijia Purifying Humidifier 3 Pro, a premium appliance that combines air purification and humidification in one device. Designed for modern homes, the new model aims to improve indoor air quality while maintaining comfortable humidity levels, making it suitable for bedrooms, living rooms, offices, and other indoor spaces.

The new humidifier is packed with intelligent features, including a high-capacity water tank, advanced air filtration, smart app connectivity, and ultra-quiet operation.
Mijia Purifying Humidifier 3 Pro Features
Powerful Humidification for Large Rooms
The Mijia Purifying Humidifier 3 Pro delivers an impressive 2,000mL of moisture per hour, allowing it to quickly improve indoor humidity. Xiaomi says the humidifier can increase humidity in a typical bedroom within approximately seven minutes, while a larger living room can reach a comfortable level in around 19 minutes.
The appliance is equipped with a generous 8-liter water tank, reducing the need for frequent refills. When operating in Sleep Mode, it can continue running for up to 16 hours on a single tank, making it suitable for overnight use.
Hygienic Water Circulation System

One common issue with humidifiers is water contamination over time. Xiaomi addresses this with a one-way spray circulation system, which prevents used water from returning to the main reservoir.
This design helps reduce bacterial buildup and keeps the water cleaner for longer periods. The system also includes:
- Electrolyzed water sterilization
- Washable antibacterial filter
- Improved hygiene during long-term operation
- Reduced water discoloration
These features help maintain cleaner mist output while lowering maintenance requirements.
Advanced 6-Layer Air Purification
Beyond humidification, the Mijia Purifying Humidifier 3 Pro functions as a capable air purifier.
It features a six-layer composite filtration system with:
- Particulate Matter CADR: 422m³/h
- Formaldehyde CADR: 247m³/h
The filtration system is designed to remove various indoor pollutants, including:
- Large airborne particles
- PM1 fine particles
- PM2.5 dust
- Formaldehyde
- Common allergens
This makes the device suitable for improving overall indoor air quality throughout the year.
Independent Humidifier and Purifier Modes
One of the standout features is its flexible operation.
Users can run:
- Air purification only
- Humidification only
- Both functions simultaneously
This allows the purifier to continue cleaning indoor air even when humidity levels are already ideal.
Smart LCD Display
The top of the device features a modern LCD dome display with automatic brightness adjustment.
The display provides real-time information, including:
- Indoor temperature
- Humidity level
- Dust concentration
- PM1 level
- PM2.5 level
This makes it easy to monitor indoor air conditions without opening the mobile app.
Smart Home Features

The purifier integrates with the Mijia smart home ecosystem, offering convenient remote management.
Users can:
- Control the device remotely through the Mijia app
- Monitor filter status
- View historical air quality data
- Adjust operating modes
- Set a preferred humidity level for automatic maintenance
The humidifier also supports XiaoAI voice commands, enabling hands-free control for compatible smart home setups.
User-Friendly Design
Xiaomi has focused on everyday convenience with several practical design improvements.
The humidifier supports:
- Top-fill water refilling
- Fully removable water tank
- Carrying handle for easier transport
- Built-in 360-degree caster wheels for smooth movement between rooms
These features make cleaning, refilling, and relocating the unit much easier compared to traditional humidifiers.
Quiet Operation
Despite its powerful airflow and humidification performance, Xiaomi claims the Mijia Purifying Humidifier 3 Pro remains exceptionally quiet.
A DC brushless inverter motor, combined with optimized airflow channels, helps reduce operating noise to just 28.1dB(A) in Sleep Mode, making it suitable for bedrooms and nighttime use.
