Xiaomi Smart Air Purifier 4 Lite is a compact floor-standing purifier for bedrooms, living rooms and other medium-size spaces. Its 360° intake draws air through a three-layer filter and delivers a particle clean-air delivery rate of up to 360 m³/h. Xiaomi rates the effective coverage area at about 25–43 m², making the Lite model suitable for regular room-scale use without the footprint of a larger purifier.

The filtration system is designed to capture fine airborne particles, including dust, pollen and pet-related debris, while activated carbon helps with common household odours and gases. An integrated laser particle sensor monitors air quality, and the front LED display shows PM2.5 information together with temperature, humidity and operating status. Night mode lowers noise and allows the display light to be reduced for bedroom use.

Wi-Fi connectivity links the purifier to Mi Home / Xiaomi Home. From the app, it can be switched remotely, scheduled and configured, and the filter-life reminder can be checked without opening the unit. Voice-control integrations may also be available depending on region.

The purifier uses a replaceable cylindrical filter, so ongoing filter availability is part of ownership. Xiaomi specifies model AC-M17-SC, dimensions of 240 × 240 × 533.5 mm and rated power up to 33 W. Formaldehyde and odour claims depend on filter condition and test environment; the stable buying points are airflow, room coverage, sensor feedback and app control.
