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.
