Smart Air Purifier 4 Lite Filter
Three-layer high-efficiency filtration to protect your health
PM2.5 and pollen filtration | Pet hair filtration | Odour elimination
Only compatible with Xiaomi Smart Air Purifier 4 Lite
It is recommended to replace the filter every 6–12 months.
All-in-one filter element Layer-by-layer filtration for good health
A primary filter, Xiaomi's high-efficiency filter and a high-quality activated carbon filter work together to purify your air and keep you healthy.
High-quality activated carbon
Xiaomi's High-efficiency filter
Primary filter
Primary Filter
360° blocking of large particles
The primary filter provides an initial filtration by filtering dust, hair, fine crumbs among other large particles and is resistant to creases, oil, acids, alkalis and more to ensure a long service life.
Dust
Fine crumbs
Pet hair
Cotton fibers
Xiaomi's High Efficiency Filter
99.97% elimination of 0.3μm particles*
The high-efficiency filter with a large surface area removes PM2.5, pollen etc. for consistent clean-air output.

The difference between Xiaomi's High Efficiency Filter and conventional HEPA Filter
Combination 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
Less clean air
The HEPA filter is made of dense fiberglass 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-down PP fibers with electrostatic technology. With greater space between fibres, large 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.
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.
Just one filter for up to one year's usage Everyday freshness with a long-lasting filter
The all-in-one filter element is durable, though performance will gradually decrease over time. It is recommended to replace the filter element every 6–12 months.
Mi Home/Xiaomi Home app connectivity Filter replacement reminders on smart devices
You can check filter usage at any time via the Mi Home/Xiaomi Home app. The app even estimates filter replacement times based on your usage.
