Xiaomi Smart Air Purifier 4 Pro | Advanced Full-Room Air Purification

Transform the air in your living space with the Xiaomi Smart Air Purifier 4 Pro. Engineered for larger rooms, it rapidly circulates up to 8,330 L of purified air per minute with a Particle CADR of 500 m³/h. Its intelligent sensor suite continuously tracks PM2.5 and PM10 levels, automatically adjusting fan speed to neutralize pollutants before they accumulate.

The three-stage filtration stack—comprising a mesh pre-filter, high-density HEPA element, and activated carbon layer—captures 99.97 % of particles down to 0.3 μm, while also trapping odors and VOCs. TÜV Rheinland allergy care certification ensures you’re breathing air free of common allergens and irritants. A user-friendly touch display shows real-time air quality readings and color-coded indicators, and Night Mode dims the screen and quiets operation to ≤ 33.7 dB(A), so your rest remains undisturbed.
