I'm considering getting the Xiaomi Mi Smart Antibacterial SKV4140GL right now.
14 January 2021 
Ambiguous device. Before purchasing, you need to have a complete understanding of what this super humidifier from Xiaomi is for 10k!
1) Definitely the design.
2) Simplicity of construction.
Water is poured into the lower compartment, volume of 4 liters. You can pour it in by removing the upper compartment (up to the max mark), or without removing it directly through the perforation (up to the sound signal or display indication). You can pour in any water, during evaporation - all salts and heavy metals remain in the tank and do not enter the air with the steam.
Evaporation works like this: disks with membranes are submerged in the water tank. The disks rotate, droplets remain in the membranes, a fan blows on these disks, and the droplets evaporate.
3) Simplicity of maintenance and absence of consumables.
You can simply change the water every day - then you won't need to service the device at all! Alternatively, you can just keep refilling with clean (filtered) water and change it once a week, wash the tank, and clean the disks once a month. If you use dirty water (from the tap), the disks and tank will turn yellow.
4) Automation via the Mi Home app.
I bought the Russian version of the device, so there were no complications, everything connected easily.
In the app, you can: set the device's operating schedule, adjust the evaporation power, the display brightness, turn the device on and off, and monitor humidity levels.
5) Accurate hygrometer (humidity meter). Shows with an accuracy of up to 1%. You do not need to buy an external hygrometer.
6) Very low energy consumption. In the 3rd mode (maximum), it consumes up to 6-8 watts. In standby mode, it almost doesn't consume at all.
But all its advantages come with significant downsides:
1) Price. I bought it almost at the lowest market price - 10,290 on Yandex Market (at the time of purchase) and didn't quite understand why it costs that much.
2) Device noise level. It indeed operates quite loudly. At level 3 (maximum power), the sound is such that even during the day, with two running desktop PCs in the room, it drowns out their noise.
At level 1 (minimum power), I couldn't fall asleep at night.
In fairness, it should be noted that once the required humidity level is reached in the room, you can switch to 1 power mode to maintain it, and there will be no noise during the day. At night, you can set it to automatically turn on from 12 - 1 am. This way, you’ll have humidified air both day and night with almost no noise.
3) Relatively low performance. At maximum power (and noise) mode, it evaporates a maximum of 350 ml of water per hour. BUT! For my 24 square meters, the device's performance was enough to maintain humidity levels at 53-55% during the winter with hot radiators and 1-2 ventilations per day. Ultrasonic ones have higher performance, but this was enough for me.
4) Malfunction. Literally on the 4th day of using the device, the fan started knocking. I went on 4pda and realized it's not a defect, but a feature of this model. Many others reported their fans started knocking. Check out 4pda, and you'll see for yourself. As a result, the already not-so-quiet humidifier turned into some sort of horrible rattler. Luckily, I was able to return this device to the store.

> Можно просто каждый день менять воду - и тогда обслуживать устройство не придётся вовсе
Менял каждый день, правда из под крана. Все равно через несколько недель начинает появляется не зелень, так красная плесень точками на дисках барабана. Бак да, чистый. Мыть барабан через 3-4 недели придется в любом случае, не от зелени, так от плесени. И так будет в любом увлажнителе/"мойке воздуха", кроме может быть парового.
> Цена
Плохо искали, спокойно можно найти за 10k, а по акциям и за 8-9k
> Громкость работы устройства
Просыпаюсь от посторонних звуков, но с эти увлажнителем на 1 скорости вполне можно спать. Днем и со второй скоростью можно находиться в одной комнате. Третья да, неадекватная.
> Точный гигрометр
Завышает на 10%, что понятно, измеряет прямо рядом с водой
Минусы в целом несущественны, особенно с учетом цены

Smart and now with a display

Introduced in the summer of 2020, the Xiaomi air washer is an updated version of the popular Smartmi Air Humidifier 2 model. The main change was the appearance of a screen that shows the current humidity level and information about operating modes. Plus, power consumption has significantly decreased: it does not exceed 8 W, therefore, even non-stop operation will not entail a significant increase in amounts in payments.

Like its predecessor, Xiaomi Smartmi Air Humidifier 2 v2 is a smart humidifier. Thanks to Wi-Fi, the model can be controlled from a smartphone, integrated into the Mi Home ecosystem, and even set up various automation scenarios. By the way, things are already better with the localization of the branded application: Chinese characters are not found in the plugin, and the English-language interface is intuitive even with minimal knowledge of the language.

But the manufacturer in the second version of the humidifier abandoned the Bluetooth module, so the model will not be able to act as a gateway in a smart home.

Moisture without the hassle

As it should be with a sink, Xiaomi Smartmi Air Humidifier 2 v2 can not only increase the humidity of the air, but also clean it. The pre-filter in front of the fan will hold coarse dirt, while the dust will remain in the 4-liter water tank and will not return back into the room. In addition, the presence of an antibacterial coating on the inner walls of the tank is claimed, which should prevent the appearance of pathogens.

The user has a separate automatic mode and three intensity levels for manual settings with a peak water flow of 260 mL / h. Accordingly, it will be necessary to replenish liquid supplies no earlier than after 15 hours, and in fact, usually, even less often. By the way, there will be no difficulties with this procedure, because the upper topping up of water is implemented.

Easy Care

Washing maintenance simplifies the dismountable drum: for a thorough cleaning, each evaporator disc can be removed, which is recommended every 2 months or during long breaks in operation. There is also a special dehumidification mode (in the Mi Home application): when it is activated, the humidifier will work for another 8 hours after the end of the water in order to dry the drum and tray.

The disadvantages of Xiaomi Smartmi Air Humidifier 2 v2 include noticeable noise at maximum performance (up to 50 dB). Otherwise, the model looks like a balanced choice in terms of price and quality, especially if you are interested in smart features.
