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 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.

  • 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.

High-precision laser PM sensor
Sensitively detects even slight pollution

The Mi Air Purifier 3H comes with a high-precision laser PM sensor that detects microscopic particulates and
reports changes in room air quality in real time. In auto mode, the purifier adjusts proactively for better cleaning.

APP+AI smart voice control*
Smart control,linking multiple smart products

With the Mi Home app, you can use your phone to keep track of your home’s air quality at all times. You can also
control the air purifier remotely and set turn-on and turn-off times. You can use the Favorite mode for highly
efficient cleaning specifically geared for your space. Supports Google Assistant so you can use smart AI voice
control.

A4 paper sized footprint
Space saving and natural feeling

Classic, super-simple design. Compact, with a
footprint smaller than a sheet of A4 paper. Fits 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

CEven 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 ener-
gy-saving light bulb.
