Xiaomi Mi Air Purifier H13 HEPA and Activated Carbon Filter

The Xiaomi Mi Air Purifier HEPA Filter (SCG4021GL) is a replacement filter for Xiaomi air purifiers. With an H13 HEPA rating, it captures 99.97% of particulates as small as 0.3 microns. It is compatible with the Mi Air Purifier 2, 2S, 2H, 3H, and Pro models. The filter traps allergens, dust, and other fine airborne matter to maintain the performance of the air purifier.

The filter uses a multi-stage system, including a pre-filter for larger debris such as hair and dust. It is designed to be easily replaced within the unit’s internal compartment. An integrated RFID chip allows the purifier to verify that a genuine filter is installed and track its remaining lifespan. The filter has a cylindrical shape, allowing air to be drawn in from all sides.
