The Xiaomi Smart Air Purifier 4 Pro delivers strong, rapid air cleaning for medium-to-large rooms, combining advanced filtration, smart sensors, and intuitive control. Its three-in-one filter setup — including a high-efficiency filter and activated carbon — traps dust, pollen, pet dander, smoke, and even fine particles as small as 0.3 µm, and reduces odors thanks to 650,000 mg activated carbon. 

With a CADR (Particle) of 500 m³/h, it pushes up to 8330 L of purified air per minute, making it capable of cleaning a 40 m² living room in around 15 minutes.The all-around 360° air intake ensures even circulation throughout the room. 

For convenience, it features a real-time PM2.5/PM10 sensor and a color-coded display strip, giving you instant feedback on air quality. The purifier adjusts automatically in Auto Mode, or you can control it manually via touch controls, the official app, or voice commands if you integrate it with a smart home assistant. 

Night mode keeps noise and light low (down to ~33.7 dB), so you can sleep peacefully while the air stays clean. Overall, the Smart Air Purifier 4 Pro is built for households that want hassle-free, high-efficiency air cleaning for everyday health and comfort.
