Xiaomi Mi Air Purifier 2 review: How to Clean The Megapolis’ Air

The Xiaomi Mi Air Purifier 2 is the company’s second air purifier. It’s the part of the Smart Home. Consequently, it supports Wi-Fi connectivity and it is controlled via the APP. However, the application mostly serves for transmitting the information about the environment and the main Mi Air function is controlled by only one button. However, this is not a small product (half a meter of height and a quarter of a meter of width). The package inclusion is quite simple: a purifier, a cable, a filter, and an instruction. The purifier looks very presentable: good materials, light colors, and a minimalistic design. There are holes at the bottom that absorb the air. The main button for the purifier control is located on the lid. When it’s pressed, the purifier launches. It is turned off via it as well. Also, it runs in 3 modes:

– Auto mode (analyzes the air and automatically increases and decreases the speed of the fan)

– Night mode (works in a silent mode, almost soundless)

– Favorite mode (allows you to adjust speed/noise via the APP).

Everything is good, but what does the purifier do?

The main key features of the Xiaomi Mi Air Purifier 2 are not the design and the convenience at all, but the air cleaning from harmful gases and small particles. The purifier is capable of circulating and cleaning the air up to 380 cubic meters per hour and it will be enough for air cleaning in a room up to 46.6 square meters. Also, it is able to independently follow the state of the environment and automatically adjust the speed of work. An indicator on the front panel lights up depending on the state of the air (red, yellow, or green). The practical properties by the manufacturer are:

– Odor removal after smoking,

– Dust removal from the air,

– Formaldehyde removal.

As a result, only the clean air remains, which is useful for the health of all inhabitants of house or office. It’s very easy to get the filter off. You just have to open the back lid of the purifier. You will be informed about its replacement time via the indicator. Usually, it serves up to 6 months. Also, it is possible to see how many days remain until the replacement of the filter in the APP.

Xiaomi Mi Air Purifier 2 Remote Control via the APP

In order to connect to Mi Home app (Android or iOS), it should be downloaded first. Thereafter, you should connect to WiFi and add the product to your Smart Home system. Eventually, a new application will appear on your device. It will be called Mi Air. By going into the app, you will see the basic interface and a conditional number of the air state. Besides controlling the main functions (on/off/switch modes), it is possible to see the temperature of air in the room, humidity, state estimation (from humid to excellent), your location (if you allow) and the quantity of remained days for filter work. There are a couple of useful additional functions as well:

  1. Protection from children (if you activate it, all the buttons in the filter will be disabled),
  2. There is a detailed instruction with pictures in the device section,
  3. A Single-button update of the purifier program (in 2-3 minutes is updating considering the device reboot),
  4. A timer for automatic on/off (it can only work when there is somebody at home),
  5. Turning off all the sound signals, in case of disturbance,
  6. Turning off all the light indicators.
  7. Xiaomi Mi Air Purifier 2


There are no complaints referring to the appearance. This is a well-looking device that can decorate any home. But it’s important to find a suitable place for it. The Xiaomi Mi Air Purifier 2 requires some space on the sides and front (10-20cm) to absorb the air.

The use of this product doesn’t improve your health significantly. However, the absence of dust in the air gives a hope we breathe a cleaner air. The only thing we are concerned about is the filter replacement time period. But if using carefully, you will do that twice a year.
