Xiaomi Mi Smart Air Purifier 4 Lite Filter

Xiaomi 34965 Mi Air Purifier Replacement Filter. The filter uses melted PP fibers with electrostatic technology. The larger spacing between the fibers allows for a greater volume of air to flow through the filter. Thanks to the lower fiber density, the filter can let air pass through at high speed, resulting in less noise. With a lower fiber density, the Xiaomi filter can release the same amount of clean air as a conventional filter while consuming much less energy.
