A three-stage filtration system combines a pre-filter, true HEPA cartridge, and activated carbon layer to trap 99.97 % of particles as small as 0.3 μm and neutralize odors and volatile organic compounds. TÜV Rheinland allergy certification guarantees rigorous removal of airborne irritants, while the built-in ionizer releases negative ions to boost freshness. Control the unit remotely via the Mi Home/Xiaomi Home app or rely on Auto Mode’s intelligent sensors to adjust fan speed based on real-time PM2.5 readings displayed on the OLED screen.
