The Xiaomi Mijia Smart Air Purifier 6 is the five-sensor, five-layer purification system that addresses the full spectrum of indoor air quality concerns in a single appliance — particle matter from PM1 to PM10, allergens including pollen, pet dander and dust mites, bacteria and viruses including H1N1 influenza, formaldehyde and TVOCs from furniture and renovation off-gassing, and general household odours — delivering 443 m³/h particle CADR and 218 m³/h formaldehyde CADR across an effective coverage area of 29–50 m², with the ability to refresh the air in an 87.5 m² room twice per hour at a ceiling height of 2.4 metres. The five-sensor system — PM1, PM2.5, dust, temperature and humidity — operates as a continuous indoor air quality monitoring station, reading pollutant concentrations across the particle size range from ultra-fine sub-micron particles through coarse allergen-scale particles, displaying live readings on the LCD colour display and transmitting data to the Xiaomi Home app for remote monitoring, historical tracking and automated response. The PM1 sensor is the most medically significant addition to the standard two-sensor (PM2.5 + dust) configuration used in lower-tier air purifiers: PM1 particles — those below 1 micron in diameter — are the size fraction that bypasses the nose and upper respiratory tract entirely, penetrates deep into the alveolar lung tissue and enters the bloodstream, carrying attached heavy metals, carcinogenic compounds and pathogenic organisms to organs throughout the body. Detection at the PM1 threshold enables the purifier to respond to the air quality events that matter most for long-term health even when PM2.5 readings appear normal.

The five-layer composite filter is the purification architecture that enables the Mijia Smart Air Purifier 6 to handle all these pollutant categories simultaneously in a single pass: the primary filter at the outermost layer captures the largest particles — pet hair, pollen grains, coarse dust — protecting the inner layers from premature loading and extending the service life of the high-efficiency filter behind it; the Xiaomi high-efficiency filter removes 99.98% of 0.3μm fine particles, which is the standard particle size used to measure HEPA-equivalent performance (0.3 microns is the hardest particle size for mechanical filters to capture, so a 99.98% rate at this size indicates high-grade filtration effectiveness across the entire PM2.5 range); the high-quality activated carbon layer uses columnar carbon — the high-density, large-surface-area format used in industrial air treatment — to adsorb formaldehyde, toluene, TVOCs and household odours; the UV light array (UVC module) uses germicidal ultraviolet wavelengths to sterilise the air passing through the filter zone, achieving 99.99% H1N1 virus removal and 99.9% E. coli, S. aureus and Pseudomonas aeruginosa removal rates confirmed by third-party testing laboratories including Korea Conformity Laboratories and Guangzhou Institute of Microbiology; and the negative ion generator releases fresh negative ions into the treated air output, which carry the same fresh-air character as the negative ion concentration found in natural forest and mountain environments and which bind to positively charged airborne particles, causing them to fall from suspension.

The allergen removal performance is independently certified: SGS Allergen Removal Testing and ITS Allergen Free Certification confirm the 98.2% one-hour pollen allergen removal rate, 99.31% cat dander removal and 98.11% dust mite allergen removal, making the Mijia Smart Air Purifier 6 suitable for household use by allergy and asthma sufferers during pollen season and in homes with pets. The filter’s nano-level high-precision filtration media are specifically engineered for allergen capture at the fibrous and particulate scale that pollen, dander and mite fragments occupy. The formaldehyde removal performance — 98% in one hour and 218 m³/h formaldehyde CADR — addresses the most persistent indoor air quality concern in new construction, recently renovated and newly furnished spaces where off-gassing from MDF, engineered wood furniture, adhesives, paints and upholstery can elevate formaldehyde concentrations significantly above safe long-term exposure limits for months to years after installation. The 32 dB(A) noise level in sleep mode is below the threshold at which most sleepers detect ambient sound, enabling continuous overnight air purification without sleep disruption. The detachable top cover enables internal air duct and fan blade cleaning without tools. The magnetic door design allows filter replacement without removing the machine from its position. Wi-Fi connectivity via Xiaomi Home app enables remote control, air quality monitoring, power scheduling and filter life tracking. Compatible with Amazon Alexa and Google Assistant for voice control. 40W rated power. 2-year warranty.
