Product Description


Mi Air Purifier 3H

380 m³/h PM CADR More effective and more powerful

Integrated 360° cylindrical Air Purifier High Efficiency Filter







The first layer removes hair, dust, cotton fibers and other large particles.

The second layer consists of a premium Mi Air Purifier High Efficiency Filter that effectively eliminates cigarette smoke, PM2.5, pollen, dust, pet dander, and other allergens as small as 0.3 microns from the air.

The third layer is an active carbon filter that absorbs formaldehyde, volatile organic compounds (VOCs) and other harmful gases.


New powerful air duct system Delivers 6330 liters of purified air per minute*

To increase the air output without changing the size of the air purifier, we had to carefully redesign every part of its air duct system. We developed a rear-tilting centrifugal fan that can move air more powerfully and cus-tom-made a new direct-current brushless motor. The newly designed pressurized air duct and the air grille form an even more efficient airflow path, considerably boosting the purifier’s performance.
