Xiaomi High Efficiency Filter

More clean air

The integrated Xiaomi filter features electrostatically charged melt-blown PP fibers with a larger fiber spacing, allowing a large volume of clean air to penetrate through the filter.

Low noise

Air easily passes through a less dense fiber filter even at high speed, resulting in significantly reduced noise.

Low power consumption

Thanks to a less dense fiber filter, the Xiaomi filter consumes less energy to achieve the same clean air volume.
