Beautiful design, let's say, high-tech modern. Intuitive control, both on the device and from a smartphone. It really cleans the air, my wife is allergic with periodic asthma symptoms, after installing the purifier, it became easier to breathe! Previously, flying dust in the sun was visible, now it is practically non-existent, practically, because it cannot be completely removed from the apartment, this is an apartment, not a laboratory :)
5) Humidity and particle air pollution sensors work perfectly, along with the purifier, we bought an air humidifier (from another company), according to Xiaomi, the humidity was 30% (critically low and harmful humidity level for apartments), now 48% and this cannot but rejoice - so it defines exactly! About the particle sensor in the air, there are numbers that mean the following. 0-75 clean air, 75-150 medium quality air in terms of harmful particles, 150-300 critically dirty, so, when I first turned it on, it showed 006, I thought it was nonsense, but when I opened the balcony for ventilation, the figure rose sharply to 156 , so the sensor works fine and that's a fact. The only thing is that with a humidifier, the indicator is 025, but this means that it reacts to micro-particles of increasing humidity. Someone says that it is noisy like an airplane, but at maximum speed, I personally fall asleep even better, it resembles the sound of a premium aircraft. Let's just say, there are no unpleasant high-frequency sounds. Display with excellent brightness, readability and light sensor. Can be controlled remotely via the app, even if you use mobile internet, if the purifier is connected to your home wi-fi. On the second day, you can see how the dust settles on the suction holes and on the filter itself, a good example of work. Once a month the filter is vacuumed and the efficiency does not drop.
