Xiaomi Smart Air Purifier 4 Lite Filter

The Xiaomi Smart Air Purifier 4 Lite filter uses a three-layer system to maintain indoor air quality. Designed specifically for the Xiaomi Smart Air Purifier 4 Lite, it captures 99.7% of airborne particles as small as 0.3 micrometres, including PM2.5, pollen, and other fine pollutants. Using this filter ensures the device operates as intended.

The filter is easy to replace without tools. Its internal structure combines electrostatic and mechanical filtration in a single unit. Under standard conditions, the filter should be replaced every 12 months to ensure consistent performance. You can track usage and receive maintenance reminders via the Mi Home app. Using authentic replacement parts ensures the purifier maintains its specified airflow and filtration efficiency.
