Model overview based on user reviews  
The SmartMi Evaporative Humidifier offers features like smartphone control and integration into smart home systems, but user experiences highlight several issues. While it operates quietly at minimum speed and is easy to disassemble, cleaning is frequently required due to dust and potential fungal growth, despite the antibacterial coating. Users report difficulty in cleaning the discs and a tendency for the device to emit unpleasant odors if not maintained properly. The humidification is described as slow and less effective, particularly in larger rooms, with some users noting that it is noisy at higher speeds. Additionally, the built-in humidity sensor is considered inaccurate, and there are connectivity issues with the Wi-Fi feature. Overall, while it has smart features, the humidifier may not meet expectations for performance and ease of maintenance.

a model with serious flaws
13 January 2021 
Connected to the Xiaomi gateway and integrated into Home Assistant, but this is not the manufacturer's merit. If you just keep topping up the water, it starts to smell after a week. You need to change the water every day and clean the plates with citric acid every 2 weeks. It participates in the overall smart home automation. I take humidity data from an external sensor. After a month of use, an annoying whistle appeared at low speed, which I turn on at night.
I connected to the xiaomi gateway and jumped into the Home Assistant.
Started whistling after a month of use.
The built-in humidity sensor is utterly inaccurate.
It’s better to take something more expensive and with filters,
7 April 2020 
If Xiaomi had a model with filters for coolers, even if it were twice as expensive, it would be much better. Everything gets clogged with dust and there's no way to clean it! I will look towards more premium products. The "smart home" is, of course, not smart at all; it doesn't clean up after itself, you have to wash everything inside every three days, so what's the point of this smart home? In the advertisement - POUR AND ENJOY, in real life - POUR, POUR OUT, DISASSEMBLE, CLEAN, SPEND 2 HOURS WASHING EACH DISK WITH A BRUSH. They are now sold for 9000 rubles, bought for 6000, at any price it's better to look at other models.
Silence,
humidification occurs slowly but well
In theory, automation can be done, which I did through a Chinese app, but after two months I realized it's a useless toy for this model
In reality - just a bucket with a cooler, you'll throw it away in half a year. Dust, dust collects inside, dust collects on the fans and it's very difficult to clean. Inside there is supposedly anti-fungal plastic, but in the first 3 weeks (cleaning once every three days) yellow fungus forms and the humidifier smells like OLD LADY, you need to soak it in citric acid, basically more hassle than with pets (I don't have any). The DISCS are a separate joke, two weeks after purchase they started to smell, become slimy and yellow, at first I didn't pay attention, later I had to wash them by hand, in the dishwasher (under cold water sprinkling, under hot I don't recommend, they can warp, but I haven't tried it), but the outcome is the same - it requires your attention, it will become your second friend))))). Nowhere is there information that in two months it turns into a pumpkin and you need to wash or clean something, in the reviews everyone is happy and that's exactly the impression you'll have when you buy it, but in reality - it's useful, but cheap and underdeveloped for the end consumer. It would be better if they made an expensive but durable model.
Dmitriyuse SmartMi Evaporative Humidifier few months
i don't recommend it, not worth the money
9 September 2021 
Died after 3 months of work. I just stopped turning it on and that's it. Before this, I can’t say that it worked super well. Humidifies small rooms, it is advisable to close the doors. Discs get dirty quickly and cleaning is a bit difficult. And also, at speed 2-3 it makes so much noise that it’s impossible to sleep. And at 1 it works very poorly, even in a small room. Before that I bought Vitec for 4000 rubles, it’s been working for 4 years now

Moisturizing and cleaning

Introduced in 2018, the device of the popular Xiaomi brand is an air washer that not only humidifies, but also cleans it: large contaminants are kept by a pre-filter, and dust is kept by water in the tank.

With a maximum humidification intensity of 240 mL/h, a full 4-liter tank will last for 16.5 hours of continuous operation. There are 3 speeds and an auto mode to choose from. The noise level does not exceed 35 dB, which is comparable to ultrasonic counterparts. It is recommended to use Xiaomi Smartmi Air Humidifier 2 in rooms up to 36 m².

Simple design

The body of the model is made of plastic and consists of two elements. In the upper part there are two fans responsible for taking in air and returning it to the room after humidification. The lower element is a tank with moistening disks, which are removed from the drum axle for cleaning, which is typical of many modern models.

It is stated that the Xiaomi Smartmi Air Humidifier 2 water tank has a special antibacterial coating on the walls, designed to prevent the development of harmful bacteria. Another feature is the practical top filling, which single water humidifiers can boast of.

smart assistant

The humidifier is equipped with a Wi-Fi module, which allows you to control it from your smartphone and integrate the device into the smart home ecosystem. In the Mi Home proprietary application (a special Smartmi Humidifier plugin), in addition to remote turning on or off, various settings are offered, including turning off sounds, changing the brightness of the backlight, completely blocking (parental control) the control panel and setting a sleep timer. Additionally, a dry air mode is available in the software: it starts an 8-hour operation after the tank is completely empty in order to dry the main components of the device.

In addition to Wi-Fi, there is also Bluetooth, due to which the humidifier can act as a gateway for other smart devices with this connection interface. The only drawback is the far from perfect localization of the Mi Home application plug-ins: Chinese characters are often found in the interface. Otherwise, Xiaomi Smartmi Air Humidifier 2 is a practical humidifier with smart features that are gaining popularity and a reasonable price tag.
