Combining two filter technologies: Electrostatic charge and mechanical filtration, Xiaomi’s High Efficiency Filter media can remove 99.97% of airborne particles of 0.3 micrometers in size and traps dust, PM 2.5, pollen, pet dander, smoke and tiny particles.
Compared to a conventional HEPA filter, Xiaomi’s High Efficiency Filter allows the air purifier to generate less noise and consume less energy by allowing more airflow to pass through the filter all the while keeping the same cleaning efficiency.
