Operating Principles

The Xiaomi Smart Air Purifier 4 Lite Filter Pro operates on a multi-stage filtration principle to ensure comprehensive air purification:

• Primary Filter: This initial layer captures larger particles such as dust, pet hair, and lint, preventing them from clogging subsequent layers and extending the overall filter life. It is resistant to bending, oil, and acids.
• Xiaomi High Efficiency Filter: This advanced filter layer is crucial for trapping fine airborne particles, including pollen, pet dander, smoke, and other allergens, down to 0.3 microns with 99.97% efficiency.
• Anti-bacterial Coating: Integrated within the filter, this coating actively neutralizes harmful bacteria, such as E. coli and Staphylococcus aureus, preventing their growth within the filter and ensuring the air released is hygienic.
• Activated Carbon Layer: The final layer consists of high-quality activated carbon, which excels at absorbing various unpleasant odors, volatile organic compounds (VOCs), and other harmful gases, leaving the air fresh and clean.

For optimal performance, monitor the filter status via the Mi Home app, which provides estimated remaining days and replacement reminders.
