A Classic Upgrade to Launch a New Classic

Since the first Xiaomi air purifier was unveiled in 2014, we've never stopped chasing superior performance.
This latest challenge was to improve performance while preserving the purifier’s classic appearance.
Our engineers redesigned the entire air duct system to increase the air purifier’s PM CADR by 22%* to 380 m³/h.

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 custom-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.

Rear-tilting centrifugal fan + Customized brushless motor.
A powerful combination that outputs massive amounts of air

Pressurized air duct
Polished inner wall for lower air resistance

Large air outlet grille Fast, even airflow

OLED touch screen display
Air quality at a glance, easy to use even at night

Simply tap the keys on the OLED display to work the purifier, and the reported info is viewable at a glance.
Room air quality data, the purifier’s operational status, etc., are all displayed clearly.
The tri-colored light ring quickly tells you the quality of the air in the room.

A4 paper sized footprint

Space saving and natural feeling

Classic, super-simple design. Compact, with a footprint smaller than a sheet of A4 paper.Fit nicely next to your sofa or under a window sill to become a natural part of your home.

Quiet and energy saving

Keep the air purifier on 24 hours a day for good air quality

Even with its upgraded performance, the Mi Air Purifier 3H is still quiet. In sleep mode, the noise level is as low as 32dB(A)*. The high-efficiency direct-current brushless motor draws only 38 W of power. When running 24 hours a day, it uses up to 1 kWh of power each day, even less than an energy-saving light bulb.
