Xiaomi Mijia Smart Air Purifier 6

The Xiaomi Mijia Smart Air Purifier 6 (AC-M25-SC) sets a new standard for home air quality management, integrating advanced multi-stage sterilization, multi-pollutant sensing, and high-volume air delivery in a minimalist white tower chassis. Capable of delivering a tested Particle CADR of 443 m³/h, this purifier rapidly circulates clean air throughout spaces ranging from 29 to 50 m² (refreshing a 10 m² room in roughly 3.5 minutes, or up to 87.5 m² at 2 air changes per hour).

At the core of the machine is a comprehensive 5-sensor environmental monitoring station. Alongside standard ambient temperature and relative humidity sensors, it integrates dedicated coarse dust/pollen detectors, a fine PM2.5 laser sensor, and an advanced PM1 sensor. The PM1 sensor monitors ultra-fine respirable particles smaller than 1.0 micron that can penetrate directly into deep lung tissue and the bloodstream. All air quality metrics and environmental states are mapped out cleanly on the integrated front-facing color LCD screen.

Air is treated through a 5-layer composite purification system. Large hair and dander are intercepted by the primary pre-filter, while the high-efficiency filter core captures 99.98% of microscopic airborne particles down to 0.3 μm (including allergens, fine dust, and secondhand smoke). An internal layer of high-porosity columnar activated carbon delivers a Formaldehyde CADR of 218 m³/h, neutralizing 98% of formaldehyde, 92.4% of TVOCs, cooking fumes, and pet odors. An integrated UVC light module neutralizes trapped pathogens on the filter surface—achieving a 99.99% H1N1 virus and bacterial elimination rate—while a negative ion generator freshens outgoing airflow. Everyday maintenance is made effortless via a magnetic rear filter access door (filter lasts 6–12 months) and a removable top grille for cleaning internal ducting and fan blades.

Key Features

• 443 m³/h High Particle CADR: Circulates high-volume clean air across rooms from 29 to 50 m², capable of refreshing standard room air in as little as 3.5 minutes.

• Advanced 5-Sensor Monitoring Array: Tracks ultra-fine PM1, PM2.5, coarse dust/pollen allergens, temperature, and relative humidity in real time.

• Ultra-Fine PM1 Detection: Specifically isolates particles under 1 μm that pose severe risks to the respiratory and cardiovascular systems.

• 5-Layer Composite Purification: Traps large debris, filters 99.98% of 0.3 μm particles, adsorbs chemical vapors/odors, sterilizes via UVC, and refreshes room air with negative ions.

• Targeted Formaldehyde & TVOC Adsorption: Delivers 218 m³/h Formaldehyde CADR with columnar activated carbon, removing up to 98% of formaldehyde and 92.4% of TVOCs within 1 hour.

• UVC Light Sterilization Module: Irradiates filter surfaces to destroy bacteria, molds, and viruses, boasting a certified 99.99% elimination rate for H1N1.

• Certified Allergen Reduction: Certified by SGS and Intertek for over 98% removal of dust mites, pollen, and pet dander.

• Quiet 32 dB(A) Sleep Mode: Acoustic duct design ensures minimal noise disruption during nighttime operation while drawing only 40W of rated power.

• Intuitive Color LCD Display: Clear circular display visualizes particulate concentrations, temperature, humidity, and operating mode at a glance.

• Smart App & Voice Automation: Connects with the Xiaomi Home app for remote scheduling, filter life monitoring, and hands-free control via Google Assistant or Amazon Alexa.

• Detachable Top Grille & Magnetic Door: Unclips easily to allow direct access for cleaning internal fan blades, paired with tool-free magnetic filter replacement.
