Xiaomi Filter for Smart Air Purifier 4 Lite Black

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.

• The high-quality activated carbon, with the sophisticated pore structure and evenly distributed carbon, effectively removes air pollutants and odour that are harmful in your home.
• 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.
• 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.
• 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.
• 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.
