Key Features of Xiaomi Smart Air Purifier 4 Compact

230 m³/h Particle CADR

The effective coverage area is 16–27 m² (GB/T 18801-2015), and the purifier can serve rooms up to 48 m² at two air changes per hour with a 2.4 m ceiling. 360° circulation draws air in from every side.

Three-in-One Filtration

An electrostatic and mechanical filter traps 99.97% of particles at 0.3 microns and reaches up to 99.99% efficiency for 0.1-micron particles. It removes allergens including pollen, dust, smoke, wildfire ash, pet hair and dander, and pet and other odours. It carries TUV Rheinland Allergy Care Certification.

Lower Fibre Density, Quieter Operation

The filter uses melt-blown PP fibres with an electrostatic charge. Compared with conventional HEPA, the lower fibre density allows higher airflow, lower noise and lower energy use. A brushless DC motor adds to the efficiency.

Whisper-Quiet Sleep Mode

Sleep mode runs at 20 dB, quieter than a library (40 dB) or an office (50 dB), and the display light can be turned off. Maximum noise is rated at ≤60 dB(A).

Sensing and Modes

A PM2.5 infrared sensor monitors air quality in real time and a four-colour indicator light shows the level. Choose Auto, Sleep or Manual mode, where you set coverage area and fan speed. Touch buttons, timed on/off, adjustable settings and a child lock are included.

Smart Control

Use the Mi Home / Xiaomi Home app for remote control and filter replacement reminders. Alexa and Google Assistant work with separately sold smart voice devices. It pairs well with the Xiaomi Smart Plug 2.

Easy Filter Replacement

Rotate and pull the filter out from the bottom. Filter life is 6–12 months. The matte, compact body works as a desktop or floor-standing unit, and power use is up to 27 W (about 0.7 kWh per 24 hours).
