The Xiaomi Mi Air Purifier uses an ultra dense Toray PP and PET HEPA filter to absorb the smallest particles, leaving only clean air. This eliminates 99% of all particles as small as PM2.5 such as bacteria, pollen, dust mites and more. The antibacterial coating also helps destroy bacterial cells. The cylinder is shaped in 360° format to ensure filtration of large particles and harmful substances.
The filter which is made of activated charcoal, is one of the most active of its kind and absorbs harmful gases that the HEPA filter cannot filter. It is combined with an anti-formaldehyde formula that effectively absorbs harmful chemicals such as formaldehyde, benzene and ammonia, as well as odours and smoke. This filter is compatible with the following devices: Xiaomi Purifier 2s, Purifier Pro and the Purifier 3H . It is recommended to replace the filter every 6 months. The status of the filter is shown in the companion app of the purifier
