Xiaomi Smart Air Purifier 4 Lite Filter | Three-Layer High Efficiency Replacement Filter | PM2.5 Pollen Pet Hair Odor Removal | Anti-Bacterial Anti-Mold Coating | Black | M17-FLP-GL
Description
This replacement filter is designed specifically for use with the Xiaomi Smart Air Purifier 4 Lite and forms the core of its air cleaning performance. It belongs to the category of home air purification accessories and is intended to restore and maintain effective filtration of indoor air in living rooms, bedrooms, kitchens, and similar spaces.
The filter uses a three-layer construction that combines a primary pre-filter, Xiaomi’s high-efficiency particulate filter, and a high-quality activated carbon layer. The primary filter provides 360-degree interception of larger particles such as dust, pet hair, lint, and fine debris, helping to protect the inner layers and extend overall service life. The high-efficiency filter media is engineered to capture up to 99.97% of particles as small as 0.3 micrometers and can reach even finer particles down to 0.1 micrometers, including PM2.5, pollen, pet dander, smoke, and microplastics. The activated carbon section features a dense pore structure to adsorb volatile organic compounds, cooking fumes, cigarette smoke, and other household odors.
The filter element is designed to work with Xiaomi’s electrostatic and mechanical filtration technology, allowing a high volume of air to pass through while maintaining fine particle capture. This construction supports lower noise levels and reduced energy consumption compared with conventional dense HEPA filters, while still delivering consistent clean air output. The cylindrical form factor with a 200 mm diameter and 310 mm height enables 360-degree air intake around the purifier for more uniform purification.
In everyday use, the filter is suitable for continuous operation in homes with dust, traffic pollution, pets, or cooking-related odors. Typical usage scenarios include allergy-sensitive environments where fine particles and pollen need to be reduced, as well as apartments where smoke and VOCs are a concern. Filter status and estimated remaining life can be monitored through the Mi Home or Xiaomi Home app when used with the compatible purifier, helping to plan timely replacement.
With a recommended replacement interval of approximately 6 to 12 months depending on air quality and usage intensity, this filter is intended to provide reliable, long-term performance as part of a regular maintenance routine. Its dedicated compatibility with the Xiaomi Smart Air Purifier 4 Lite and integrated multi-layer design make it a practical choice for maintaining stable air purification efficiency over time.
