The hidden air hazards surrounding your home require a fully effective 360° solution
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.
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
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.
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
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.

Works as described
Noticed and immediate difference in air quality. Dust and pollen really get to me. Had this on overnight and my usual sniffles and red eyes were gone.
Exactly what I needed delivered overnight...
I am a health professional working in L2 conditions and I don't have great air circulation in my room which is important in managing Delta risk. After some research I worked out which air purifier would be the best option. Then I went online thinking that it would likely be a bit of a wait coming in from overseas. Nope, it was in stock and arrived for the start of my first day in L2. Now it is sitting making virtually no noise.
When I printed some forms about 15 minutes ago the smell vanished in no time flat.
No problem spotted so far!
The pollen has just arrived in force at my place, there are track marks in the yellow pollen from my car it's that thick as I live near a forest. The purifier is helping me big time so much so I actually bought a second one. Well worth the money if you suffer from hayfever try it
I've been having allergy symptoms lately and this is just the thing I needed. It looks beautiful, has a nice minimalistic but useful display, and has app control. Great purchase
Clean air at last!
I have a Mitsubishi dehumidifier which is supposed to filter the air but this thing is next level. The air smells fresh at night and my asthma is way better. I can see the humidity level and turn on the dehumidifier as well if I need to do so. Getting it to work with the app took time but I just leave it on automatic all the time even when I'm away for a few days. Dust under my bed also seems less.
Well made, works well
Bought this for the formaldehyde filtering capability, to help remove the smell from new carpets. It worked better than expected! The filter you get with the unit is the HEPA filter, so you have to buy that filter additional.
Well made product - does a great job. I use it on high in the bedroom for a while in the evening, and then change it to night mode, which is a lot quieter.
Moves quite a bit of air on full tilt.
You can use without the app, including dimming of turning off the front display.
If you use it with the app, you can schedule then to turn it on/off.
Quick to improve air quality.
Easy to use and very quiet. Love that you can turn off the light at night. It only took a couple of days to improve the quality of air to a 1 rating.
Great product vesus price.
great product as I expected it to be.
A life changer
This air purifier is super quiet and works like a dream. Been having allergy problems & bedroom was stuffy & now the room smells like fresh air & sleeping easy - no blocked up nose in the morning. Lots of setting options - couldn’t get app working but not worried about that.
Very happy with purchase & PB Tech made it easy to buy with prompt delivery.
Good value for money
Does the job. NOt very good at deodorizing.
Works great, I can leave this on overnight because it's very quiet. I normally suffer from bad hay fever but have not since running this in my room.
The only bad aspect is the app won't connect to this device and from looking online many others have this issue.
Quiet and Impressive air purifier
This is worth getting as it does work and makes the room a pleasant place to be in. The app is great too and lets you know how long before the filter needs to be replaced, as well as giving you room temp and humidity.
