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.
Conventional HEPA filter
Less clean air
HEPA filter is made of dense fiberglass to trap particles, which means that less clean air gets through the filter.
Noisy
Large volumes of air are forced through a dense HEPA filter, requiring higher fan speed, which will generate more noise.
Higher energy consumption
In order to get cleaner air, the HEPA filter requires the motor to run at a higher speed, which causes higher energy consumption.
Xiaomi's High Efficiency Filter
Cleaner air
Xiaomi's High Efficiency Filter integrates melt-blown PP fibers with electrostatic technology equipped with bigger fibers space, which enables a large volume of clean air to get through the filter.
Low noise
Less dense fiber filter is easy to have the air passed even in a high speeds, resulting in much lower noise.
Lower energy consumption
Thanks to a less dense fiber filter, Xiaomi's High Efficiency Filter consumes less energy to achieve the same volume of clean air.
