The difference between Xiaomi’s High Efficiency Filter and a conventional HEPA filter

Combines two filtration technologies: Electrostatic charging and mechanical filtration. Xiaomi’s High Efficiency Filter can remove 99.97% of airborne particles down to 0.3 microns, trapping dust, PM2.5, pollen, pet hair, smoke, and even the smallest microplastics.

Compared to a conventional HEPA filter, Xiaomi’s High Efficiency Filter allows the purifier to produce less noise and consume less power, enabling more airflow through the filter while maintaining the same cleaning efficiency.

Conventional HEPA filter

• Less clean air: Made of dense fiberglass to trap particles, meaning less clean air passes through.

• Noisy: Large air volume forced through dense HEPA filter requires higher fan speed, creating more noise.

• Higher energy consumption: The motor needs to run faster to deliver more clean air, increasing power use.

Xiaomi High Efficiency Filter

• More clean air: Uses PP fibers with electrostatic technology, with a larger fiber space, allowing more airflow through.

• Low noise: Less dense fibers allow air to pass at higher speeds with much less noise.

• Lower energy consumption: Thanks to the less dense fiber filter, it consumes less energy for the same amount of clean air.
