The difference between Xiaomi's High Efficiency Filter and a conventional HEPA FilterCombination of two filter technologies: Electrostatic and mechanical filtration. Xiaomi's High Efficiency Filter media can remove 99.97% of airborne particles as small as 0.1 micrometres and traps dust, PM 2.5, pollen, pet dander, smoke and even the smallest microplastics. The filtration rate of Xiaomi's High Efficiency Filter media is 99.97% for fine particles of up to 0.3 microns, and can reach up to 99.99% for particles as small as 0.1 microns.

Disclaimer: Filter media performance is tested by China Testing & Inspection Institute for Household Electric Appliances (Report Number: WCv-21-40115). Due to the technical specifications of the filter media, the test environment and parameters may differ.

Conventional HEPA filter

Less clean air

The HEPA filter is made of dense fibreglass to trap particles, which means that less clean air gets through the filter.

Noisy

Large volumes of air are forced through the dense HEPA filter, meaning a higher fan speed is required, which generates more noise.

Higher energy consumption

In order for the HEPA filter to release more clean air, the motor must run at a higher speed, which translates into a higher energy consumption.

Xiaomi's High Efficiency Filter

More clean air

Xiaomi's filter uses melt-blown PP fibres with electrostatic technology. With greater space between fibres, larger volumes of air are able to pass through the filter.

Low noise

With a lower fibre density, the filter allows air to pass through at high speeds, resulting in less noise.

Lower energy consumption

With a lower fibre density, Xiaomi's filter is able to release the same volume of clean air as a conventional filter, but with a much lower energy consumption.
