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 99.99% of airborne particles of 0.1 micrometers in size and traps dust, PM 2.5, pollen, pet dander, smoke and tiny particles

Conventional HEPA Filter

Less clean air

HEPA filter is made of dense fiberglass to trap particles, which means that less clean air get through the filter

Noisy

Large volume air is forced to get through a dense HEPA filter, requires higher fan speed, which will generate higher noise

Higher 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

Xiaomi’s High Efficiency Filter

More clean air

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

Low noise

Less dense fibers filter is easy to have the air passed even in a high speed, which results in much lower noise

Lower energy consumption

Thanks to a less dense fibers filter, Xiaomi’s filter consumes less energy to achieve the same volume clean air
