The Xiaomi Smart Air Purifier 4 Compact is designed to support cleaner indoor air in bedrooms, living spaces, and small offices with a compact, space-saving form factor. It uses a high-efficiency 3-in-1 filtration system capable of capturing up to 99.97 percent of particles as small as 0.3 microns, including dust, pollen, and pet dander. With a particle CADR of 230 m³ per hour and 360-degree air intake, it is suitable for rooms with an effective coverage area of approximately 16 to 27 square metres.

The purifier features automatic adjustment of purification speed based on real-time air quality, which is displayed through an OLED touch control panel and a four-colour indicator light. Quiet operation, with noise levels as low as 20 dB in sleep mode, allows comfortable use during night-time or working hours. The brushless DC motor is designed for energy-efficient operation with a rated power consumption of 27 W.

Smart connectivity is supported via Wi-Fi, allowing control and monitoring through the Xiaomi Home app. The purifier is compatible with Google Assistant and Alexa for supported voice control functions. Its cylindrical design, lightweight build, and floor-standing installation make it easy to place in different indoor environments.
