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

Combine two filter technologies: Electrostatic charge and mechanical filtration, Xiaomi's High Efficiency Filter media can remove 99.97% of airborne particles down to a minimum size of 0.1 micrometers and traps dust, PM 2.5, pollen, pet dander, and smoke even the smallest microplastics. For fine particles up to 0.3 microns, Xiaomi’s high efficiency filter media filtration rate is 99.97%, and for particles as small as 0.1 microns, the filtration rate can reach to 99.99%.

Conventional HEPA Filter

Less clean air

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

Noisy

Large volume air is forced to get through a dense HEPA filter, requires higher fan speed, which will generate higher noise.

Higher 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.

Xiaomi’s High Efficiency Filter

More clean air

Xiaomi’s filter integrated melt-blown PP fibers with electrostatics technology equipped with bigger fibers space, which enables a large volume clean air to get through the filter.

Low noise

Less dense fibers filter is easy to have the air passed even in a high speed, which results in much lower noise.

Lower energy consumption

Thanks to a less dense fibers filter, Xiaomi filter Xiaomi’s consumes less energy to achieve the same volume clean air.

Disclaimer: The 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.

Just one filter can last for up to a year Everyday freshness with a long-lasting filter

Although the all-in-one filter is durable, its performance may gradually degrade over time. For best results, it is recommended to replace the filter every 6–12 months.

Xiaomi Home app connectivity Smart filter replacement reminders

You can monitor the filter status at any time on the Xiaomi Home app, allowing you to estimate when the filter should be replaced based on your daily usage.
