Xiaomi Smart Air Purifier 4 – smart air purifier with HEPA filter and ionizer
Powerful and quiet purification up to 400 m³/h

3-in-1 filtration with activated carbon
The HEPA layer captures 99.97% of particles as small as 0.3 μm, while activated carbon absorbs odors and VOCs. All-day protection for allergy sufferers.
Smart control and OLED display
Monitor air quality in real time, change modes with a touch, and control it via the Xiaomi Home app or by voice (Google Assistant, Amazon Alexa).
The Xiaomi Smart Air Purifier 4 takes care of air quality in rooms up to about 48 m². Thanks to 360° intake and output up to 400 m³/h, it can clean a 20 m² room in roughly 10 minutes. The three-layer filter combines a pre-filter, a HEPA layer, and high-quality activated carbon that absorbs odors and volatile organic compounds (VOCs). Released negative ions contribute to a feeling of freshness and comfort.
The practical OLED display shows air quality in real time and lets you adjust purification modes with a single touch. With the Xiaomi Home app, you can set schedules, monitor temperature, humidity, and pollution levels, or start purification before you get home. Support for Google Assistant and Amazon Alexa adds convenient voice control.
