Mi Air Purifier 3H
More effective and more powerful
Is the air you breathe actually clean?
The continuous release of formaldehyde from furniture,
harmful gases, foul odors, bacteria, viruses, pollen,
pet dander and other allergens suspended in the air,
are endangering your family’s respiratory health.
The hidden air hazards surrounding your home

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 and other harmful substances
The first layers removes hair,dust,cotton
fibers and other large particles
The second layer consists of a premium HEPA filter that effectively eliminates 99.97% of bacteria, viruses, cigarette smoke, PM2.5, pollen, dust, pet dander, and other allergens as small as 0.3 microns from the air.
It is also effective towards finer particles of 0.1 microns.
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 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.
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.
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.
Noise as low as
