The difference between Xiaomi‘s High Efficiency Filter and conventional HEPA Filter
Combine two filter technologies: Electrostatic charge and mechanical filtration, Xiaomi's high efficiency filter media can remove 99.97% of airborne particles down to a minimum size of 0.1 micrometers and traps dust, PM 2.5, pollen, pet dander, and smoke even the smallest microplastics. For fine particles up to 0.3 microns, Xiaomi's high efficiency filter media filtration rate is 99.97%, and for particles as small as 0.1 microns, the filtration rate can reach to 99.99%.
Conventional HEPA filter
Xiaomi's High Efficiency Filter
Less clean air
HEPA filter is made of dense fiberglass to trap particles, which means that less clean air get through the filter.
More clean air
Xiaomi's High Efficiency 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
Large volume air is forced to get through a dense HEPA filter, requires higher fan speed, which will generate higher noise
Low 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
In order to get more clean air, HEPA filter requires the motor to run at a higher speed, which causes higher energy consumption.
Lower energy consumption
Thanks to a less dense fibers filter,Xiaomi's High Efficiency Filter consumes less energy to achieve the same volume clean air.
