Key Features of Xiaomi Smart Air Purifier 4 Lite

360 m³/h Particle CADR

Output reaches up to 6,000 litres of clean air per minute, with a formaldehyde CADR of 120 m³/h and an effective coverage area of 25–43 m². A 360° all-round intake pulls air in from every direction.

Triple-Layer Filter

The three-in-one filter removes 99.97% of 0.3 μm particles. The high-efficiency layer has an expanded area of 20,000 cm², and the activated carbon content is 450,000 mg, 1.8 times that of the Mi Air Purifier 3C. It targets dust, pollen, pet hair and dander, smoke, cooking fumes, pet odours, VOCs, formaldehyde and toluene, and reduces airborne H1N1, E. coli and other bacteria. It is TUV Rheinland Allergy Care certified.

Efficient Filter Technology

Melt-blown PP fibres with larger fibre spacing combine electrostatic and mechanical filtration. Xiaomi states the same cleaning efficiency as conventional HEPA with less noise and lower energy use. Filter life is 6–12 months, and replacement is a three-step open-up job.

Real-Time LED Display

The display shows PM2.5, indoor temperature and humidity, Wi-Fi status and operating mode. A colour-coded light strip has four levels: fresh and clean, low, moderate and high pollution. A high-precision laser sensor detects particles as small as 0.3 μm.

Modes and Noise

Choose Auto, Night or Favourite mode. Night mode runs as low as 33.4 dB(A) and turns off the display light. Maximum noise is ≤61 dB(A).

App and Voice Control

The Mi Home / Xiaomi Home app provides remote control, timed on/off, air-quality monitoring, filter reminders and a child lock. Amazon Alexa and Google Assistant work with separately sold smart voice devices. Maximum power is 33 W, or about 0.8 kWh per 24 hours.

Compact Design

The 24 × 24 cm base is smaller than an A4 sheet. The square body has chamfered edges, a symmetrical grille and an anti-oxidant ABS finish.
