The lever at the bottom can be swing to lock and unlock the filter cartridge.
This is the power cord, coming in a 3-pin plug, you may need a converter to fit into your local socket.
The outer layer of the filter cartridge is PET (unsaturated polyester) mesh-net, it is used to isolate the hair, fabrics, fines and other large suspended solids.
Filter mesh-net come in 161 folded layers, forming a blocking hollow drum. Filter is HEPA (high efficiency particulate air filter fine particles), which can be expanded to the length of 7m. For the adsorption of PM2.5, PM0.3, pollen and other particulate matter, officially declared effective filtration rate of 99.3% for PM0.3. The official specs for the coconut shell activated carbon is in the innermost layer, invisible to us...... purifier activated carbon is mainly used for adsorption of formaldehyde, benzene, ammonia and other inorganic toxic gases.
For ease of cleaning, the outlet of the fan can be opened. Turn the grill to open the top-level grille, unscrew the fan cover to remove the fan and fixed rotary vane.
Surrounding rotary vane grille are protection / isolation, at the bottom you can see the officially mentioned four air ducts.
The air purifier can controlled by the app, the app's main function is the remote control switch, and understand and getting info on the surrounding air quality. Applications will be combined with the local weather forecast (although only China cities' forecast is available) and even air quality, providing recommendations to open the windows or switch on the air purifiers.
It can also be operated without the App and can be used normally, the operation buttons on the air purifier can be toggled between "Auto, Sleep, High speed decontamination" modes, with the led light to be lit at the side to indicate the current mode.
The air purifier is in the same category of appliance / devices using the Mi Home App to manage and control, they includes the Mi Smart Socket, Yi Ants Web Cam, water purifiers etc.
Other intelligent features of the app includes filter replacement reminder, timer switch, remote switch, run-time exception alerts (blockage), automatic start (automatically turn on when detected the air quality is poor) and the like.
Although the main function is only purifying the air, but the additional app functions make it standout among other air purifiers in its price range.
The air purifier's area of 26 x 26 cm is slightly shorter than an A4 Paper (29.7cm), and 73.5cm in height, a little shorter than a normal desk (76cm). For good purification of air, you will need to keep a distance of 10cm between the back of the purifier and the wall and leaving a distance of 20cm from the side of the purifier and the wall.
Purification design is by a double fan that create internal negative pressure, suction from the bottom of the mesh, and forcing air through the filter from the upper part of the fan.
Official recommended usage area is 28 - 48 square meters, which will meet the needs of ordinary living room to purify the room, but for office space approaching 150 square meters, it will only filter air surround the purifier. Similar to other purifiers using activated carbon, you can smell the unique slight acidity charcoal at the outlet.
The noise produced from the lowest "Sleep" mode, with human ear listen closely nearby, is the "whirring" sound of the wind, a bit like a refrigerator, with a sound value of about 50 dB when measured by meter.
When set to the "Auto" mode, the wind volume and noise level have increased a little, maintained at between 50 - 55 dB respectively.
When set at "High-speed" mode, the volume level will go directly close to 80 dB, and indeed vibrate a bit.
May be taken into account the noise level, the high-speed mode will automatically switched to "Auto" mode after 15 minutes. When keeping at this level, it can easily reach the official target of 406 m³ / h purification efficiency (with official spec of purification 48 m² space required 12 minutes), but having to endure this high speed fan volume.

Six Differentiating factors for Mi Air Purifier
1) Smart phones to remote control the air purifier
Traditional air purifiers have to control its operations using the buttons located on the device. When we are away from the device, we are completely unable to control the device. After returning home after a hard days' work, we need to switch on the air purifier and wait for a while before we can get rid of the bad air. Or, after leaving the house, we suddenly remember the air purifier is not switch off, apart from the costs of electricity and affecting the mood of the day, there is no way we need to make a special trip home to switch off the air purifier!
2) Visual view of indoor air quality visualization
When you feel the air quality in the room is not good, do you know how bad it is? And whether you know whether the air quality outside the window is better than the indoor air quality? Mi air purifier has a built-in high-sensitivity detection module that not only accurately display the total amount of suspended particles in the air, but can present also the value on the mobile phone. Whether you are at home or away, you can now view the air quality anytime and anywhere.
3) Filter replacement reminder
Most people do not know when to replace a new filter. Either replace early, spending unnecessary, or replace it too late, where the filter is no longer effective in purifying the air. Mi air purifier filter replacement reminder is specially designed to automatically send a reminder message through the mobile app, when the filter needs to be replaced.
4) Purifying at fixed time
If you feel a click operation is not smart enough, then you can use the more intelligent feature by using the timing function of the mobile app, where you can schedule the purifying time.You do not need any special attention, just need to follow your habits set the timer in advance, when to switch on and when to switch off.
5) Automatic alert on abnormal behaviors and exceptions
If the air purifier encountered anomalies during operation, such as fans jammed with foreign matter, sudden increase of smoke, mi air purifiers report these abnormal situations by sending alert messages through the mobile app. To avoid deterioration of unforeseen circumstances.
6) Reminder to open the windows for ventilation for outside air
While the clean indoor purified air can always be better, but unpolluted outdoor air is closer to nature. The Mi Home app provides air quality data for major Chinese cities from China Meteorological Center. When the outdoor is a blue sky, with better quality than the indoor air, the app will send a reminder asking you to open the windows, walk into into the nature. Of course, do not worry even if the haze come back, the good quality indoor air purification is always waiting for you.
For me, air purifier is really important. I really want to make sure that at least at my house, the air is purified. These days outside air is very polluted. pure rocky mountain air
