The difference between Xiaomi's High Efficiency Filter and 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 micrometers 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 up to 0.3 microns, and can reach up to 99.99% for particles as small as 0.1 microns.

Conventional HEPA filter

Xiaomi's High Efficiency Filter

Less clean air

More clean air

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

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

Noisy

Low noise

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

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

Higher energy consumption

Lower 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.

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.

Disclamier: Filter media performance is tested by China Testing & Inspection Institute for Household Electric Appliances (Report Number: WCv-21-40119). Due to the technical specifications of the filter media, the test environment and parameters may differ.
