Xiaomi Mi Air Purifier 4 Pro Filter

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. The 650000mg high-quality activated carbon*, with the sophisticated porous structure and evenly distributed carbon, effectively removes air pollutants and odour that are harmful in your home. Combining two filter technologies: Electrostatic charge and mechanical filtration, Xiaomi's High Efficiency Filter media can remove 99.97% of airborne particles of 0.3 micrometers in size and traps dust, PM 2.5, pollen, pet dander, smoke and tiny particles. Compared to a conventional HEPA filter, Xiaomi's High Efficiency Filter allows the air purifier to generate less noise and consume less energy by allowing more airflow to pass through the filter all the while keeping the same cleaning efficiency.
