Xiaomi has introduced a new compact air purifier in China, with the Mi Air Purifier 6C now available for pre-order at an introductory price of 999 yuan. Designed for small and medium-sized homes, the new model combines a space-saving body with real-time air-quality monitoring and a multi-stage purification system.
Rather than focusing only on basic particulate filtration, the Mi Air Purifier 6C places particular emphasis on formaldehyde detection and removal, while also monitoring PM2.5, temperature, and humidity.
Compact Design for Smaller Living Spaces
The Mi Air Purifier 6C is designed to fit into rooms where floor space is limited. Xiaomi says the purifier occupies approximately 0.063 square meters, roughly comparable to the footprint of an A4 sheet of paper.
This compact air purifiers footprint makes it easier to position in apartments, bedrooms, rental properties, and other relatively space-constrained environments without taking up a large portion of the floor.
The design also allows the purifier to provide air-quality information directly on the device rather than requiring users to open an app every time they want to check indoor conditions.
Circular LCD Shows Formaldehyde Levels in Real Time
One of the main highlights is the purifier’s circular LCD display.
The screen can reportedly show formaldehyde concentration down to the thousandth decimal place, while also displaying changes in concentration over time through a curve. Alongside formaldehyde monitoring, the device incorporates sensors for PM2.5, temperature, and humidity.
This gives users a more detailed overview of indoor air conditions and makes it possible to see how air quality changes after the purifier starts operating.
The display also supports automatic brightness adjustment. At night, it can lower its brightness to reduce visual distractions while the purifier continues running.
Mi Air Purifier 6C Claims 99% Formaldehyde Removal in Two Hours
Purification performance is another major part of Xiaomi’s positioning for the Mi Air Purifier 6C.
The purifier has a reported particulate CADR of 603 m³/h, while its maximum air volume reaches approximately 9,500 liters per minute. Its reported formaldehyde CADR is 381 m³/h.
According to Xiaomi’s published figures, the Mi Air Purifier 6C can achieve a 99% formaldehyde removal rate within two hours, with a stated maximum applicable area of 68 square meters.
These figures highlight why understanding how formaldehyde air purifiers work can be useful when comparing purification performance between different models.
Six-Layer Purification System
Inside the Mi Air Purifier 6C is a six-element composite purification system designed to address different types of indoor pollutants.
The system consists of:
- An initial filtration layer
- An antibacterial filter layer
- A high-density formaldehyde removal filter
- A nano-scale fine filtration layer
- A dedicated formaldehyde-removal carbon layer
- A UV ultraviolet sterilization layer
Xiaomi says the formaldehyde-focused portion of the system uses an amino reaction to decompose formaldehyde, while the dedicated carbon layer is designed to adsorb TVOCs and odors.
The company positions this combination as a way to deal with both airborne particles and common indoor odors while reducing concerns about secondary pollution from captured formaldehyde.
Filter Replacement Costs 199 Yuan
The purifier is not designed as a maintenance-free appliance. Xiaomi lists the replacement filter at 199 yuan, with an expected service life of approximately six to 12 months.
Users can check the remaining filter life either through the purifier’s display or through the Xiaomi app. This makes it easier to track replacement timing instead of relying solely on a fixed calendar reminder.
Actual filter life can vary depending on how frequently the purifier operates and the conditions of the room where it is installed.
Xiaomi App Adds Remote Control
The Mi Air Purifier 6C also connects to Xiaomi’s smart-home ecosystem.
Through the Xiaomi app, users can reportedly control the purifier remotely, change operating modes, and set schedules. The Xiaomi smart home devices also support Xiaomi’s voice-control functions, allowing compatible users to operate it through voice commands.
For quieter operation, the purifier includes a sleep mode that reduces fan speed and operating noise. This makes the mode particularly suited to bedrooms and nighttime use.
The combination of remote control, scheduling, filter-life monitoring, and automatic screen brightness adjustment gives the Mi Air Purifier 6C a stronger smart-home focus than a basic standalone air purifier.

A Compact Air Purifier With a Strong Focus on Formaldehyde Monitoring
At 999 yuan, the Xiaomi Mi Air Purifier 6C combines a compact footprint with detailed air-quality monitoring, a six-stage purification architecture, and Xiaomi smart-home controls.
Its most distinctive feature is arguably the combination of real-time formaldehyde monitoring and active purification. The circular display gives users direct access to indoor air data, while the app adds remote control and maintenance information.
The claimed 99% formaldehyde removal figure should be understood as Xiaomi’s official test claim rather than a guarantee of real-world results. Final performance will depend on the installation environment and operating conditions.
The Mi Air Purifier 6C is currently available for pre-order in China, with the 999-yuan launch price making it Xiaomi’s latest compact option for users looking for a connected air purifier with a particular emphasis on formaldehyde monitoring.
