The Xiaomi Anti-formaldehyde air purifier filter is combined with an aerodynamic 360 degree cylindrical design with a triple filter. The filter consists of a filter for the bigger particles, a HEPA 11 one and a three-layer carbon layer for a very effective cleaning. The balance between strength and quality makes the Xiaomi Mi Air Purifier Anti-formaldehyde filter unique!
Because the filter is made with PET (polyethylene terephthalate), the outer layer is 3 to 5 times stronger than comparable models. The filter is resistant to folding, grease, acids and most solvents. Nasty particles are a thing of the past because the filter absorbs all kinds of nanoparticles. Hair, dust and small particles are effectively eliminated. In the app you can see when the filter is in need of replacement. 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.
