The difference between Xiaomi's High Efficiency Filter and conventional HEPA
FilterCombining 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.
Conventional HEPA filter
Xiaomi's High Efficiency Filter


Less clean air
More clean air
HEPA filter is made of dense fiberglass to trap particles, which means that less
clean air get through the filter.
Xiaomi's filter integrated melt-blown PP fibers with electrostatics technology
equipped with bigger fibers space, which enables a large volume clean air to get
through the filter.
Noisy
Low noise
Large volume air is forced to get through a dense HEPA filter, requires higher
fan speed, which will generate higher noise.
Less dense fibers filter is easy to have the air passed even in a high speed,
which results in much lower noise.
Higher energy consumption
Lower energy consumption
In order to get more clean air, HEPA filter requires the motor to run at a
higher speed, which causes higher energy consumption.
Thanks to a less dense fibers filter, Xiaomi's filter consumes less energy to
achieve the same volume clean air.
*The filter media performance is tested by China Testing & Inspection Institute
for Household Electric Appliances (Report Number: WCv-21-40119). Due to the
technical specifications of the filter media, the test environment and
parameters may differ.
