The difference between Xiaomi's High Efficiency Filter and a regular HEPA FilterXiaomi's High Efficiency Filter media combines two filtration techniques—electrostatic charge and mechanical filtration—to remove 99.97% of airborne particles sized 0.3 micrometers, trapping dust, PM 2.5, pollen, pet dander, smoke, and various other small pollutants. Unlike standard HEPA filters, Xiaomi's High Efficiency Filter allows the air purifier to function more quietly and consume less energy while improving airflow through the filter, ensuring similar cleaning effectiveness.

Standard HEPA filter

Less clean air

The HEPA filter is made of dense fiberglass that is intended to trap particles, leading to a reduction in the amount of clean air flowing through it.

Noisy

Forcing a significant amount of air through a dense HEPA filter requires higher fan speeds, leading to increased noise levels.

Elevated energy consumption

To obtain cleaner air, a HEPA filter requires the motor to run at a higher speed, leading to increased energy consumption.

Xiaomi's Effective Filter

More clean air

Xiaomi's High Efficiency Filter integrates melt-blown PP fibers with electrostatic technology, designed with increased fiber spacing that permits a substantial volume of clean air to flow through the filter.

Low noise

Less dense fiber filters enable air to pass through even at high speeds, resulting in a notable decrease in noise.

Reduced energy usage

Xiaomi's High Efficiency Filter consumes less energy to deliver the same amount of clean air thanks to its less dense fiber filter.

The China Testing & Inspection Institute for Household Electric Appliances assesses the filter media's performance based on the GB/T 6165-2021 standard. (Report Number: WCv-21-40115). Variations in the test environment and parameters may occur due to the technical specifications of the filter media.
