Xiaomi Mi Air Purifier Formaldehyde Filter S1 SCG4026GL

The ultra-dense HEPA filter measures 7.7m when fully extended. Although ideal for air purification, this creates high air resistance. To get around this, considerable thought has been put into creating the folding process.

How well a filter performs depends on its purification ability and aerodynamic design. Supplied by the top 3 US air purifier manufacturers, the filter combines an aerodynamic 360° cylindrical design with a powerful triple-filter consisting of primary, HEPA and activated carbon layers. Easy to use and replace, its balance of power and quality is what makes Mi Air Purifier so effective.
