The difference between Xiaomi's High Efficiency
Filter and conventional HEPA Filter
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.
*The filter media performance is tested by China Testing & Inspection Institute for Household Electric Appliances (Report Number:
WCv-21-40115). Due to the technical specifications of the filter media, the test environment and parameters may differ.
