A good product, I advise you to try it.

If they figured out the availability of devices when setting up different regions (despite the fact that devices are actively supplied in 2022, but you still need to set China, as for the same repeater), it would be much more convenient.

Specifically for this filter, they should have added a simple power control knob so they don't have to wait for an app on their phone to open.
A simpler solution: the second custom power mode, which, almost sure, can be done even purely programmatically by ating the firmware (the filter can ate itself, just press the button in the application).

Because of these two inconveniences, I put 4 and 5, but as a filter it works pretty well.

Pros

- able to purify the air very well - control via the application on the phone allows you to control it from anywhere where there is Internet -branded (or copies) hepa 11 filters are not too expensive and are easily available

Cons

The main drawback comes down to firmware and control: the dust detector is designed only to detect fine particles, so if the air in the room is already clean enough, the filter will operate at a very low speed in automatic mode, but, of course, I want it to take on some of the coarse dust, so you need to set it to manual mode, you can adjust the power for it only by phone, there is only one preset for manual mode settings. The second drawback: the Chinese have different regions, a different set of devices, as a result it can be somewhat inconvenient: the filter that I received refuses to be detected for China, but the wi-fi repeater (signal amplifier) does not connect for 2022, but it works for Chinese region. In general, I had to clone the application and create a 2nd account. On the technical side of the filter itself, it is noisy, in order for it to effectively filter dust, it is necessary to set high power, and in the absence of any sound insulation in this design, it starts to make a lot of noise, so the power must be reduced to 1/3-1/4, and this is inconvenient do for the above reason.
