Summary

I love the design of the Xiaomi Mi Air Purifier, it looks polished and minimalist, it does not feel cheap, and the build quality is perfect. The device does its job very well and works very-very quiet. It cleans indoor air not only from particulate matter but also from bad odors. The app is very simple and intuitive, but still gives you a lot of useful features.

It is not a secret that air pollution has a major impact on our health and life expectancy. According to the World Health Organisation, Air pollution is a biggest environmental health risk, particularly for heart disease and strokes. The most dangerous impact for our life is a particulate matter that has a diameter less than 2.5 micrometers (it's 50 times thinner than a human hair) - those particles called PM2.5. Nowadays, there are a lot of air purifiers on the market, those devices use a complex system of filters to clean air from PM2.5 particulate matter. Today I'll review one of them - a smart, powerful and nice designed Xiaomi Mi Air Purifier 2nd generation. This device will be a good choice for those who build a smart home.

The HEPA filter located at the bottom of the air purifier. It absorbs polluted air from the bottom from every direction and expels air from the top of the device. Mi Home app alerts when it is time to change the filter. Approximately the filter lasts about 4-6 months, depending on your usage.

On the front side of the device located two LED indicators. One of them shows a current level of PM2.5, green color - air in the room is clean, orange and red color indicate very polluted air. The second LED shows current mode: Auto, Sleep or Favorite.

There are only two control buttons on the Mi Air Purifier. One located on the back side, it changes a brightness of the LED indicators. The second button located on the top of the device, it turns on/off the purifier and changing the cleaning mode.

How does Mi Air Purifier work?

The Mi Air Purifier equipped with two powerful motors and 360° cylindrical high-density EPA filter that removes all the dust, pollen, mold, bad odor, pet fur and all the particles bigger than 0.3μm. Thanks to its 360 degrees form, it takes in the air more efficiently in every direction. The filter can be easily replaced when it needed. The motors absorb air from all directions and the aerodynamic pressure system expels air upwards with great force.

What is amazing in Mi Air Purifier compared to other devices — it works very-very quiet. The device has 3 modes: Sleep, Auto, and Favorite. Auto mode switches between the modes according to the environment, Sleep runs quieter, and Favorite mode boosts the power to a maximum which takes about 10 minutes to clean the air in a 21m2 room. Xiaomi claims it makes 31dB of noise when it silent mode is on, however, I never hear any noise when it works in auto mode despite the fact that the fan is spinning. If it works in turbo mode, it is a little bit noisy and the noise level is approximately 70dB, but it is still comfortable and doesn't bother me at all. In the max mode, it can clean air in an average room just in 10 minutes.

Smart control via Smartphone App

The Xiaomi Mi Air Purifier is a part of Xiaomi Smart Home environment, it can be connected to your smartphone via Wi-Fi and controlled by the Mi Home app. This app is very simple and intuitive, but still gives you a lot of useful features. You can schedule power on/off, switching between a few working modes, monitor your indoor PM2.5 estimate level, temperature, humidity, comfort level and how much clean air has been delivered. Also, the app informs you when the filter should be replaced. The manufacturer recommends replacing the filter every 6 months. You can change a brightness of led indicator, turn on a parent control, check and update the firmware of the device.

What is great in this device, it can learn your habits and preferred settings. For example, it turns on "Night mode" when you sleep, changes the mode to "Auto" when you wake up, automatically turned off the purifier when you leave home.
