Xiaomi Air Purifier 3H OLED Touch Display Smart APP with HEPA Filter

FEATURES
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.
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.

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

The best no show socks
The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.
