Xiaomi Smart Air Purifier 4 Review – Design and Features

Xiaomi Smart Air Purifier 4 is not a small unit. But upon opening the magnetic-door design filter area, I can understand why. The unit has a huge 3-in-1 filter that can trap many pollutants within for up to one year (depending on usage). With a large surface area and high content of quality activated carbon, it’s a highly efficient filter consisting of Pre-Filter (traps larger particles like pet’s hair), Xiaomi’s High Efficiency Filter (traps small particles as small as 0.3 microns), and High-Quality Activated Carbon (traps harmful gases and odour).
