The Mi Air Purifier 3H is designed to improve air quality in indoor environments, offering various modes and features for effective purification and user convenience.
The primary function of the Mi Air Purifier 3H is to filter airborne particles and harmful gases, providing cleaner and healthier air. It achieves this through a multi-stage filtration system, including a filter that should be installed correctly in its compartment. The device is equipped with a laser particle sensor to detect the concentration of PM2.5 particles in the air, and a temperature and humidity sensor to monitor environmental conditions. The purifier automatically adjusts its operation based on air quality, offering different modes to suit various needs, from quiet operation for sleeping to high-speed purification for rapid cleaning.
The Mi Air Purifier 3H is designed for straightforward operation. To turn on the purifier, users simply tap the "On/Off & Mode Button." Subsequent taps on this button allow users to switch between different operating modes:
The device features an OLED display that shows real-time information such as PM2.5 levels, temperature, humidity, and the current operating mode. The display also includes an Air Quality Indicator, which changes color (Green for 0-75 µg/m³, Orange for 76-150 µg/m³, Red for 150 µg/m³ or higher) to visually represent the air quality. Users can adjust the display's brightness or turn it on/off using the "Display On/Off Button" located on the back of the purifier.
For optimal performance, it is recommended to place the purifier in a suitable location, maintaining a distance of at least 20 cm between the air inlets and walls or other objects. Keeping doors and windows closed during operation is also advised for a better purifying effect.
The Mi Air Purifier 3H can be integrated with the Mi Home / Xiaomi Home app, allowing users to control the device remotely. The app enables advanced features like setting manual purification parameters and monitoring air quality from a smartphone. If the phone cannot connect to the purifier, the Wi-Fi can be reset by simultaneously pressing and holding the On/Off & Mode button and the Display On/Off button for five seconds until a beep is heard.
The purifier provides important notifications regarding its filter status:
Regular maintenance is crucial for the Mi Air Purifier 3H to ensure optimal performance and longevity. Before any maintenance, the purifier must be turned off and unplugged.
The purifier is designed with safety in mind, and several warnings are provided to prevent damage or injury. These include not pulling, twisting, or bending the power cord excessively, using only the provided power cord, and unplugging the purifier before maintenance or moving it. Users are also cautioned against sticking fingers or foreign objects into protective or movable parts, air inlets, or air outlets, and to keep objects like hair or fabrics away from these areas to prevent blockages. The device should not be used near open flames, high-temperature appliances, or in unstable, extremely hot, humid, or damp locations. Children aged 8 years and above, and persons with reduced physical, sensory, or mental capabilities, can use the appliance with supervision and instruction, but children should not play with or perform cleaning and user maintenance without supervision.
