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.
Integrated 360° cylindrical HEPA filter
The three-layer filter effectively removes PM2.5, formaldehyde
The first layer removes hair,dust,cotton
fibers and other large particles.

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.

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.
