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 based on GB/T
6165-2021 standard. (Report Number: WCv-21-40115). Due to the technical specifications of the filter media, the test environment
and parameters may differ.
