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 micrometres 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 while keeping the same cleaning efficiency.

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 filter allows air to easily pass even at high speeds, which results in much less noise.

Higher energy consumption
Xiaomi Smart Air Purifier 4 Pro Filter
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 less dense fibers, Xiaomi's filter consumes less energy to achieve the same volume of clean air.
